Description

  The present invention relates to a printed matter, a voyeurism prevention system, and the like for preventing information from being voyeurized by a terminal device including an imaging device. More specifically, the present invention relates to a printed material, a voyeurism prevention system, and the like that prevent information printed on printed materials (books, magazines) in a bookstore or the like from being voyeurized by a portable terminal with a digital camera.

  In recent years, with the increase in the number of portable terminals equipped with digital cameras and the miniaturization of these portable terminals, it has become possible to take an image of a subject without the knowledge of others. For this reason, so-called digital shoplifting, in which a user of a mobile terminal voyeurs information printed on a book without purchasing the book, is increasing in a bookstore or the like.

  The information printed on the book includes, for example, a map of a restaurant, a clothing store, an address, a telephone number, a URL (Uniform Resource Locator), a store information identification code, or a two-dimensional code indicating them (for example, a QR code ( Store-related information such as registered trademark) and Quick Response code).

  Conventionally, as a technique for preventing such voyeurism, there are an imaging disturbance method using a light beam outside visible light, an imaging prevention method using an imaging prohibition signal, and the like (for example, see Non-Patent Document 1).

  In addition, as a method for obstructing imaging using light rays other than visible light, a technique for projecting an infrared message or the like on a screen is disclosed separately from an image or the like. The wavelength range of light that can be seen with the naked eye is about 400 nm to 800 nm, whereas the sensitivity of a digital camera is about 400 nm to 1100 nm (see, for example, Non-Patent Document 2). For this reason, an infrared message cannot be seen with the naked eye, but when it is imaged with a digital camera or the like, it is recorded on the image, thereby obstructing the imaging or making it possible to determine that it has been voyeurized. .

  Furthermore, there is a technology that enables embedding of a digital watermark by light outside visible light more optimally by adjusting the intensity of light outside visible light irradiated on the screen in accordance with the brightness and frequency of images and the like. .

In addition, (1) Technology that interferes with imaging by installing an infrared lamp near the subject to prevent voyeurism, and irradiating infrared from this infrared lamp. (2) Irradiating the subject with infrared light and the amount of infrared light. (3) Irradiating a subject with infrared rays to interfere with imaging, but when a specific ID is recognized, irradiate for a predetermined period of time. There is also a technology to stop and enable imaging.

Furthermore, as an imaging prevention method by an imaging prohibition signal of a portable terminal with a digital camera (mobile terminal),
(1) Technology for turning off the imaging function of a mobile terminal or the like when an imaging prohibition signal is received from a device installed near an object to be prohibited from imaging (2) The terminal device of the person to be imaged (subject) A technique for transmitting an imaging prohibition signal that disables the imaging function from the subject terminal device to the photographer's mobile terminal upon receiving a signal during imaging transmitted from the mobile terminal of the subject (3) Imaging prohibition information embedded in the subject There is also a technology that makes it impossible to use the captured image by painting it when the mobile terminal detects it.
Digital shoplifting prevention measures, [online], [March 30, 2005 search], Internet, <URL: http: //tantei.web.infoseek.co.jp/shoplist> CQ Publisher, “Basics and Applied Production of CMOS / CCD Sensor”, Transistor Technology, February 2005, Vol. 42, No. 2, p. 106-111

  However, with conventional methods of obstructing imaging by light outside visible light, it is necessary to irradiate books and magazines with infrared rays in order to prevent digital shoplifting at bookstores, etc., preventing image capture of copyright-free information, etc. There is a problem that even information that does not need to be captured cannot be imaged.

  In addition, in the conventional imaging disturbing method using light rays other than visible light, the imaging in the bookstore is uniformly disturbed. For example, in the bookstore, the user who purchased the content of specific store related information There are also problems such as being unable to provide conditional services, such as making it possible to obtain only that information, or allowing bookstore members to obtain specific information within the bookstore.

  Furthermore, the printed matter absorbs light rays having wavelengths other than those visible to the naked eye. That is, for example, a blue printed material reflects light having a wavelength of blue, but absorbs light having a wavelength other than blue, so that it looks blue to the naked eye. Also, black prints appear black to the naked eye because they absorb light of all wavelengths. For this reason, even if it irradiates infrared rays, it will be absorbed by printed matter, and there also existed a problem that it was difficult to make it fully unreadable.

  In the imaging prevention method using the imaging prohibition signal, the imaging apparatus needs a function of turning off the imaging function when the imaging apparatus receives or detects the imaging prohibition signal. For this reason, there has been a problem that it is not effective in preventing digital shoplifting by a portable terminal with a digital camera already on the market.

The present invention solves the aforementioned problems,
(1) Preventing voyeurism of information recorded on printed matter by a portable terminal with a digital camera in a predetermined area such as a bookstore or a convenience store. (2) Conditions such as payment of information charges in the predetermined area. (3) When the printed material is purchased and taken out of the specified area, the information recorded on the printed material is subject to conditions outside the area, such as free of charge. It is an object to provide a means that makes it possible to acquire

The digital camera includes a charge-coupled device (CCD). The mobile terminal with a digital camera is realized by a mobile phone, a PDA (Personal Digital Assistant), or the like, and may be a digital camera having a two-dimensional code reading function or a predetermined communication function. The portable terminal with a digital camera is hereinafter abbreviated as “mobile terminal with camera”.

<< First Embodiment >>
FIG. 1 is a diagram for explaining a printed matter according to the first embodiment of the present invention. A printed matter 100 according to the first embodiment will be described with reference to FIG. For example, the printed material 100 is obtained by writing information indicated by reference numerals 1 to 3 on a paper 111. Here, a case where the medium of the printed material 100 is paper 111 will be described as an example, but the present invention is not limited to this.

  Reference numeral 1 is store-related information written in characters, and shows a store phone number (0422-xx) and a URL (not shown for violation of public order and morals). Reference numerals 2 and 3 are two-dimensional codes of store related information.

Information indicated by reference numerals 1 and 2 is printed on the paper 111 with normal printing ink or the like. On the printed information (reference numerals 1 and 2), an infrared fluorescent paint that transmits visible light out of the irradiated light, but reflects fluorescently the infrared rays irradiated by the infrared irradiation device installed in the bookstore. (First infrared fluorescent paint) is applied (see region 110). That is, the information indicated by reference numerals 1 and 2 is masked by the first infrared fluorescent paint. The two-dimensional code indicated by reference numeral 3 is printed by a second infrared fluorescent paint that reacts (fluoresces) with light having a wavelength different from that of the first infrared fluorescent paint. Here, the second infrared fluorescent paint is described as being a paint that does not react with infrared rays irradiated by an infrared irradiation device in a bookstore, but reacts with infrared rays of other wavelengths.
In each embodiment, the case where an infrared fluorescent paint is used for the paint will be described as an example. Instead, an infrared reflection that transmits visible light among reflected light but reflects infrared light of a predetermined wavelength is used. A paint may be used.

  2A shows the printed matter of FIG. 1 viewed with the naked eye, FIG. 2B shows an image of the printed matter of FIG. 1 taken with a camera-equipped mobile terminal under infrared, and FIG. 2C shows the sunlight and incandescent light. It is the figure which illustrated the image which imaged the printed matter of FIG. 1 with the portable terminal with a camera. With reference to FIG. 1, an image of the printed matter 100 captured by the camera-equipped mobile terminal will be described with reference to FIGS.

First, in FIG. 2A, the region 110 of the printed material 100 is masked with the first infrared fluorescent paint. The first infrared fluorescent paint transmits visible light, and even when infrared rays are irradiated by an infrared irradiation device (infrared lamp) 5, the infrared rays that are fluorescent cannot be seen with the naked eye. Therefore, in the bookstore irradiated with infrared rays by the infrared irradiation device 5, customers in the bookstore can read the store-related information indicated by reference numeral 1 and the two-dimensional code indicated by reference numeral 2 with the naked eye. Further, since the two-dimensional code indicated by reference numeral 3 is printed with the second infrared fluorescent paint, it cannot be read with the naked eye.
However, if a bookstore user purchases the printed material 100 and brings the printed material 100 to a place where there is little infrared light, such as a room where the light of a fluorescent lamp is irradiated, the user can use a camera-equipped mobile terminal with normal paint. The information indicated by the printed codes 1 and 2 can be directly imaged.

  In FIG. 2B, the area 110 of the printed material 100 is masked by the first infrared fluorescent paint, and the two-dimensional code indicated by reference numeral 3 is also an infrared ray irradiated by the infrared irradiation device 5 in the bookstore. Since it is printed with the 2nd infrared fluorescent paint which does not react, it cannot image with the portable terminal with a camera in the bookstore which irradiated infrared rays. That is, by irradiating the printed material 100 with infrared rays in the bookstore, it is possible to prevent the information indicated by reference numerals 1 to 3 from being voyeurized by the mobile terminal with a camera.

  In FIG. 2C, since the sunlight and the incandescent lamp include a wide wavelength component of light, the first infrared fluorescent paint in the region 110 of the printed matter 100 fluoresces under the sunlight and the incandescent lamp. . Therefore, even if it tries to image with the portable terminal with a camera outside a bookstore, the information shown with the codes | symbols 1 and 2 of the printed matter 100 cannot be imaged.

  However, since the two-dimensional code indicated by reference numeral 3 is printed with the second infrared fluorescent paint that reacts under sunlight or an incandescent lamp, the two-dimensional code indicated by reference numeral 3 is imaged with a portable terminal with a camera. be able to. That is, if a user of a bookstore purchases the printed material 100 and brings the printed material 100 under sunlight or an incandescent lamp, the user can take an image of the two-dimensional code indicated by reference numeral 3 with the camera-equipped mobile terminal. That is, the bookstore user can acquire the store-related information indicated by the two-dimensional code.

  FIG. 3 is a diagram showing the photosensitivity distribution of the photoreceptor and the spectral distribution of the light source with respect to the light wavelength. In FIG. 3, reference numeral 10 is the sensitivity of the naked eye, reference numeral 11 is the sensitivity of the digital camera, reference numeral 12 is the spectral distribution of sunlight, reference numeral 13 is the spectral distribution of the incandescent lamp, reference numeral 14 is the spectral distribution of the fluorescent lamp, and reference numeral 15 is the bookstore. The spectrum distribution of the infrared irradiation apparatus 5 (refer FIG.2 (b)) which irradiates the inside is shown. Reference numeral 16 indicates the fluorescence sensitivity of the first infrared fluorescent paint of the present embodiment, and has an infrared wavelength near 900 nm. Reference numeral 17 indicates the fluorescence sensitivity of the second infrared fluorescent paint of the present embodiment, and has an infrared wavelength of around 1000 nm. As shown in FIG. 3, the first infrared fluorescent paint and the second infrared fluorescent paint do not fluoresce under a fluorescent lamp and in a place with low infrared rays (for example, at home), and the digital camera (camera-equipped mobile terminal with camera) does not fluoresce. ) Is not determined. Further, under the infrared irradiation device 5 in the bookstore, the first infrared fluorescent paint fluoresces and is imaged by the digital camera, but is not discriminated by the naked eye. Furthermore, under sunlight and incandescent lamps, the first infrared fluorescent paint and the second infrared fluorescent paint fluoresce, and both can be imaged by the digital camera but not discriminated by the naked eye. .

Thus, in the printed material 100,
(1) Mask the information you do not want to voyeur in the bookstore with the first infrared fluorescent paint,
(2) After purchase, print the information you want to image with the second infrared fluorescent paint,
(3) Irradiate infrared rays with an infrared irradiation device 5 that irradiates infrared rays that the first infrared fluorescent paint reacts with the printed matter 100 but the second infrared fluorescent paint does not react with an area that is not desired to be voyeurized, such as in a bookstore. As a result, it is possible to prevent sneak shots of information on the printed material 100. In addition, for purchasers of printed matter 100, information can be directly imaged in places with low infrared rays such as indoors, and from the information printed with the second infrared fluorescent paint in the outdoors or under incandescent lamps, Store related information can be acquired.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described. The second embodiment is characterized in that when the camera-equipped mobile terminal 21 (see FIG. 6) reads information recorded on the printed material 100 in the bookstore, the information can be acquired on condition that the user pays for the fee. And Constituent elements similar to those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 4 is a diagram illustrating a printed material according to the second embodiment. A printed material 100 according to the second embodiment will be described with reference to FIG.

  The printed matter 100 includes a two-dimensional code indicated by reference numeral 33 in addition to the information indicated by reference numerals 1 and 2 described above. The two-dimensional code denoted by reference numeral 33 indicates the encrypted store-related information and the URL of the access server that stores the decryption key for this information. The two-dimensional code indicated by reference numeral 33 is printed on the paper 111 with the first infrared fluorescent paint. The URL of the access server is described by a combination of address information of the access server and identification information of store related information, for example.

  For example, in the two-dimensional code indicated by reference numeral 33, the encrypted store-related information and the URL “http://server.ne.jp/param?book=jyouhoushi” of the access server are described. Here, the address information part of the access server is “http://server.ne.jp/”, and the identification information part of the store related information is “book = jyouhoushi”. In other words, when the camera-equipped mobile terminal that has read this information accesses the access server via the network and requests a decryption key, the mobile server with the address "http://server.ne.jp/" The identification information “book = jyouhoushi” is transmitted to request a decryption key for the store related information. That is, a store-related information acquisition request is made.

  FIG. 5A is a view of the printed matter of FIG. 4 viewed with the naked eye, and FIG. 5B is a diagram illustrating an image obtained by capturing the printed matter of FIG. 4 with a camera-equipped mobile terminal under infrared rays. With reference to FIGS. 1 to 4, an image of the printed matter 100 captured by the camera-equipped mobile terminal will be described with reference to FIGS.

  First, FIG. 5A is similar to FIG. 2A of the first embodiment, because the area 110 is masked with the first infrared fluorescent paint that transmits visible light. The code 1) and the two-dimensional code (code 2) can be read with the naked eye.

  Further, since the two-dimensional code indicated by reference numeral 33 is printed with the first infrared fluorescent paint, it cannot be read with the naked eye. In a place where there is little infrared light, such as a room under a fluorescent lamp, the mobile terminal 21 with a camera can directly image information indicated by reference numerals 1 and 2.

  Under the infrared rays in FIG. 5B, the area 110 of the printed material 100 is masked by the first infrared fluorescent paint, so that the camera-equipped mobile terminal 21 cannot capture the information indicated by reference numerals 1 and 2. On the other hand, since the two-dimensional code indicated by reference numeral 33 is printed with the first infrared fluorescent paint, it can be imaged by the mobile terminal 21 with camera. That is, in the bookstore, the camera-equipped mobile terminal 21 can obtain the encrypted store-related information and the URL of the access server. Incidentally, the camera-equipped mobile terminal 21 can obtain the encrypted store-related information and the URL of the access server even in sunlight or incandescent light, as in FIG. 5B.

  FIG. 6 is a block diagram illustrating a configuration of an information transmission system using the printed material according to the present embodiment.

The system includes a mobile terminal 21 with a camera, a bookstore server 22 that transmits position information (bookstore identification information) to the camera-equipped mobile terminal 21 by wireless communication, an access server 25, a data server 26 of a publisher, a content server 27, and these. A network 24 to be connected is included.
The bookstore server 22 may be a wireless LAN base station (hot spot or the like) connected to the network 24. For example, the base station may perform wireless communication with a terminal device within a predetermined short distance, and may transmit area identification information indicating a predetermined area as position information to the terminal device. The network 24 is, for example, an IP (Internet Protocol) network, the Internet, or a LAN (Local Area Network).

  The camera-equipped mobile terminal 21 acquires an image (two-dimensional code or the like) output from a built-in digital camera (imaging device). A function of reading information written on the printed material 100 from the image (two-dimensional code), that is, a function of interpreting the two-dimensional code and converting it into address information or the like is provided. The camera-equipped mobile terminal 21 has a function of communicating with the content server 27 or the access server 25 via the network 24 based on the address information. Furthermore, the camera-equipped mobile terminal 21 has a wireless communication function for receiving area identification information transmitted from the bookstore server 22.

  The access server 25 is a server that stores a magazine name, a page, and store identification information (identification information of store-related information) in which store-related information is posted. The access server 25 is, for example, a portal site (Web server) that publishes store-related information collected from various publishers via the network 24. When the camera-equipped mobile terminal 21 reads the two-dimensional code, it accesses the access server 25 via the network 24. The access server 25 stores magazine names, pages, store identification information, decryption keys, and the like of magazines in which store-related information is posted in the storage unit (see Table 1). Table 1 is a table illustrating information stored in the storage unit of the access server 25. In Table 1, on the page “BB” of the magazine name “AA”, store-related information of the store identification information “CC” is encrypted, and the decryption key of this store-related information is “DD”. It is shown that.

例えば、アクセスサーバ２５は、カメラ付き携帯端末２１から店舗識別情報「ＣＣ」を含む復号キーの取得要求を受け取ったとき、このカメラ付き携帯端末２１の利用者の料金の支払い等所定の条件を満たせば、店舗識別情報「ＣＣ」の復号キーをカメラ付き携帯端末２１へ送信する。

For example, when the access server 25 receives a decryption key acquisition request including the store identification information “CC” from the camera-equipped mobile terminal 21, the access server 25 can satisfy predetermined conditions such as payment of a fee for the user of the camera-equipped mobile terminal 21. For example, the decryption key of the store identification information “CC” is transmitted to the camera-equipped mobile terminal 21.

The publisher's data server 26 also stores information on the magazine name, page, store identification information, and decryption key of the magazine in which the store related information is posted. The stored information is the same information as the contents exemplified in the above-described Table 1, and therefore description thereof is omitted.
The content server 27 is a server that stores store-related information and the like in the storage unit. Each of the bookstore server 22, the access server 25, the publisher data server 26, and the content server 27 includes a storage unit, an arithmetic processing unit, an input / output interface, a network interface, and the like, and is a computer that transmits and receives data via the network 24. It is realized by. Moreover, the number of each server and the portable terminal 21 with a camera is not limited to the number shown in FIG.

  FIG. 7 is a flowchart showing the operation of this system when a user images store-related information with a camera-equipped mobile terminal in a bookstore. With reference to FIGS. 1 to 6 as appropriate, the operation of the present system when the user images store-related information with the camera-equipped mobile terminal 21 in the store will be described with reference to FIG. Here, a case where the printed material 100 is a magazine will be described as an example.

  The content server 27 transmits store-related information requested to be published in a magazine (printed material 100) to the publisher data server 26 (S71).

  The publisher prints the store-related information and the two-dimensional code of the store-related information with a normal paint, and masks them with the first infrared fluorescent paint. At the same time, the publisher converts the magazine name, page, and store identification information on the store-related information, information on the encrypted store-related information, and the URL of the access server 25 into a two-dimensional code. Print with 1 infrared fluorescent paint and publish in a magazine.

  Further, the publisher's data server 26 transmits the magazine name, page, store identification information, and the like in which the store related information is posted, together with the decryption key of the store related information to the access server (S73). The publisher then ships the magazine to the bookstore.

  On the other hand, when the user enters the bookstore with the camera-equipped mobile terminal 21, the camera-equipped mobile terminal 21 receives the bookstore identification information from the bookstore server 22 by wireless communication or the like (S74).

  Next, when the user takes an image of a magazine with the camera-equipped mobile terminal 21, the inside of the bookstore is irradiated with the infrared irradiation device 5, so that the two-dimensional code printed with the first infrared fluorescent paint (FIG. 4). Image 33) is imaged (S75). In S75, store-related information masked with the first infrared fluorescent paint (see reference numeral 1 in FIG. 4) and a two-dimensional code (see reference numeral 2 in FIG. 4) are not captured. The camera-equipped mobile terminal 21 transmits an acquisition request for store-related information (decryption key for store-related information) including the contents of the two-dimensional code and the bookstore identification information received in S74 to the access server 25 (S76). That is, when the camera-equipped mobile terminal 21 acquires the image (two-dimensional code) captured by the digital camera, the portable terminal 21 interprets the two-dimensional code and, based on the address information indicated in the interpreted information, the access server 25 via the network 24. Send an information acquisition request to

  Upon receiving the store-related information acquisition request transmitted in S76, the access server 25 determines whether or not bookstore identification information is included in the acquisition request (S77). Here, when the store-related information acquisition request includes the bookstore identification information, the access server 25 charges the store-related information to the camera-equipped mobile terminal 21 and purchases it as an acquisition condition for the information according to the bookstore identification information. A confirmation message is returned (S78). If the store-related information acquisition request does not include the bookstore identification information, it is determined that it is outside the bookstore (purchased and taken out of the bookstore), the process proceeds to S81, and the access server 25 uses the decryption key. Send.

  The camera-equipped mobile terminal 21 displays the store-related information fee and the purchase confirmation message on a display unit (not shown) such as a liquid crystal monitor (S79). Here, if there is an input from the input unit (not shown) of the camera-equipped mobile terminal 21 to reply to purchase request for store-related information, the camera-equipped mobile terminal 21 sends this purchase request message to the access server 25. Transmit (S80).

  When the access server 25 receives this purchase request message, the access server 25 reads the decryption key of the store related information from the storage unit and transmits it to the camera-equipped mobile terminal 21 (S81). In response, the camera-equipped mobile terminal 21 decrypts the encrypted store-related information and displays it on the display unit (S82). That is, the camera-equipped mobile terminal 21 acquires store-related information, and the user of the camera-equipped mobile terminal 21 can use the store-related information.

  The charge for the store-related information here may be added to a part of the communication charge of the camera-equipped mobile terminal 21 and charged to the user, or the user charges the access server 25 in advance (payment). ) It may be subtracted from the prepaid portion. In addition, the access server 25 may pay the publisher for providing the store-related information to the publisher from the collected fee, and may pay the installation fee for the bookstore server 22 to the bookstore.

  By doing in this way, when the user of the camera-equipped mobile terminal 21 images information published in a magazine with the camera-equipped mobile terminal 21 in the bookstore, the information is obtained by satisfying a predetermined condition such as fee payment. Can be obtained.

<< Third Embodiment >>
Next, a third embodiment of the present invention will be described. In the third embodiment, when the camera-equipped mobile terminal 21 (see FIG. 6) reads information on the printed material 100 at a place outside the bookstore, the identification information indicates that this information is read outside the bookstore. It is characterized in that (bookstore identification information) is also read. Specifically, the printed matter 100 of the present embodiment is characterized in that the predetermined area includes outside-bookstore identification information printed with the second infrared fluorescent paint. This outside bookstore identification information corresponds to outside area identification information in the claims.

  In the present embodiment, the camera-equipped mobile terminal 21 reads out-bookstore identification information in an area outside the bookstore (under sunlight or incandescent light), but reads out-bookstore identification information in an area inside the bookstore (under infrared). Absent. In other words, in the bookstore area (under infrared), the camera-equipped mobile terminal 21 does not transmit the non-bookstore identification information to the content server 27. Therefore, for example, even if the bookstore server 22 (see FIG. 6) is not installed in the bookstore, the content server 27 determines whether the information acquisition request from the camera-equipped mobile terminal 21 is from the bookstore or outside the bookstore. Can be determined.

That is, the camera-equipped mobile terminal 21 can acquire the outside bookstore identification information under sunlight or incandescent light.

  FIG. 10 and FIG. 11 are flowcharts showing the operation of the information transmission system when a user images store-related information with a camera-equipped mobile terminal outside a bookstore. The operation of the system when the user images the store-related information with the camera-equipped mobile terminal 21 outside the bookstore will be described with reference to FIGS.

  First, store related information for requesting publication in a magazine (printed material 100), information obtained by encrypting the store related information, store identification information, and the URL of the content server 27 are sent from the content server 27 to the publisher's data server. 26 (S1001).

  The publisher prints the store-related information and the two-dimensionally encoded store-related information with a normal paint, and masks them with the first infrared fluorescent paint. At the same time, the publisher converts the magazine name, page, and store identification information on the store-related information, information on the encrypted store-related information, and the URL of the access server 25 into a two-dimensional code. Print with 1 infrared fluorescent paint and publish in a magazine. In addition, the publisher prints the information obtained by converting the outside-bookstore identification information into a two-dimensional code with the second infrared fluorescent paint and publishes it in a magazine. The publisher data server 26 stores the magazine name, page, store identification information, and URL of the content server 27 in which the store-related information is posted in the storage unit.

  Table 2 is a table illustrating information stored in the storage unit of the data server 26. In Table 2, the store-related information of the store identification information “CC” is posted on the page “BB” of the magazine name “AA”, and the URL of the content server 27 that transmits the decryption key of the store-related information is “EE”. ".

  Then, the data server 26 of the publisher transmits the magazine name, page, and store identification information in which the store related information is posted to the access server 25 (S1003).

  Publishers ship magazines to bookstores. Then, the user purchases a magazine at a bookstore, and the two-dimensional code (reference numeral 43 in FIG. 8) and the second printed with the camera-equipped mobile terminal 21 with the camera in the sunlight, such as outdoors. The two-dimensional code (symbol 44) printed with the infrared fluorescent paint is imaged (S1004).

  Next, the camera-equipped mobile terminal 21 interprets the captured two-dimensional code 43 and acquires a magazine name, a page, and store identification information in which store related information is posted. Further, the two-dimensional code of the sign 44 is interpreted to obtain the identification information outside the bookstore. Then, the camera-equipped mobile terminal 21 transmits to the access server 25 an acquisition request (decryption key acquisition request) for store-related information including a magazine name, a page, store identification information, and bookstore identification information for posting the store-related information. (S1005).

  In the access server 25, it is determined whether or not the outside store identification information is included in the received store-related information acquisition request (S1006).

  Here, when the store-related information acquisition request includes non-bookstore identification information, the access server 25 sends the received store-related information acquisition request (magazine name, page, store identification information, etc.) to the publisher's data. Transfer to the server 26 (S1007). In S1006, when the access server 25 determines that the store-related information acquisition request does not include identification information outside the bookstore, that is, the store-related information acquisition request is made from the camera-equipped mobile terminal 21 in the bookstore. When the access server 25 determines that the store related information is purchased, the access server 25 confirms the purchase of the store-related information with respect to the camera-equipped mobile terminal 21 in the same manner as the steps S78 to S80 of FIG. 7 in the second embodiment. That is, when the access server 25 transmits an information purchase confirmation message to the camera-equipped mobile terminal 21 and receives a purchase request message from the camera-equipped mobile terminal 21, the process proceeds to S <b> 1007.

  Note that when there are a plurality of publisher data servers 26 in this system, the publisher data server 26 to which the access server 25 should transfer the store-related information acquisition request is the magazine name included in the store-related information acquisition request. Or based on store identification information. For example, the access server 25 stores information indicating the URL (address) of the data server 26 of the publisher of the magazine for each magazine name and store identification information in the storage unit, and requests acquisition of store related information. When received, the publisher's data server 26 is specified using the magazine name and store identification information included in the acquisition request as keys.

  The data server 26 of the publisher in FIG. 11 searches the storage unit of the data server 26 using the store identification information included in the store-related information acquisition request received in S1007 in FIG. Specify (S1101).

  Then, the data server 26 of the publisher transfers the information (magazine name, page, store identification information) received in S1007 to the content server 27 (S1102).

  The content server 27 searches the storage unit using information (magazine name, page, store identification information, etc.) transferred from the data server 26 as a key, and specifies store related information (decryption key for store related information) (S1103). ). And the decoding key of this shop relevant information is read from this memory | storage part, and it transmits to the portable terminal 21 with a camera (S1104). The camera-equipped mobile terminal 21 decrypts the store-related information (encrypted store-related information) read from the magazine using the received decryption key, and displays it on the display unit (S1105).

  In addition, under a fluorescent lamp such as at home or in a place with little infrared light, the two-dimensional code printed with the first infrared fluorescent paint (reference numeral 43) and the two-dimensional code printed with the second infrared fluorescent paint (reference numeral 44). Is not imaged, but a two-dimensional code (symbol 2) printed with normal paint is imaged. Accordingly, the camera-equipped mobile terminal 21 can directly access the content server 27.
