It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
As shown in fig. 1, the present disclosure provides a security element 1 comprising an image layer 11, on which image layer 11 conductive patterns 111 and non-conductive patterns 112 are provided. In a state that the conductive pattern 111 is in contact with the touch screen, the conductive pattern 111 can change capacitance distribution of the touch screen; in a state where the non-conductive pattern 112 is in contact with the touch screen, the non-conductive pattern 112 cannot change the capacitance distribution of the touch screen surface layer.
In one embodiment, the security element is identified using capacitive technology and through a touch screen. The number of patterned layers 11 of security element 1 may be one or more, and the number of conductive patterns 111 and non-conductive patterns 112 may be one or more. When the conductive patterns 111 contact the touch screen, the distribution of capacitance on the surface of the touch screen can be changed through the conductive patterns 111, so that the touch screen responds; the non-conductive pattern 112 does not allow the touch screen to respond when it is contacted. The touch screen is set to an active state in which contact data can be recorded.
The touch screen may be any of a variety of existing capacitive touch screens. For example, the capacitive touch screen is a four-layer composite glass screen, the inner surface of the glass screen and the interlayer are respectively coated with a layer ITO (Indium Tin Oxides) to form a capacitor, and four electrodes are led out from four corners of the capacitive touch screen.
When a finger of a person directly or a material with better conductivity contacts the surface of the capacitive touch screen, the finger or the conductive material and the working surface form a coupling capacitor due to the electric field of the human body, and the high-frequency signal is connected to the working surface, the finger or the conductive material absorbs a small current which flows out of electrodes on four corners of the capacitive touch screen respectively, and the current flowing through the four electrodes is in proportion to the distance from the finger to four corners of the capacitive touch screen theoretically, and the controller obtains the contact position of the conductive pattern and the surface of the screen through precise calculation of the four current proportions to generate response.
The conductive patterns 111 are formed by a material with better conductivity, and when the conductive patterns 111 contact the capacitive touch screen, the conductive patterns 111 can change the capacitance distribution of the touch screen surface, so that the touch screen responds.
When the non-conductive pattern 112 contacts the capacitive touch screen, since the conductivity of the material of the non-conductive pattern 112 contacting the surface of the capacitive touch screen is not high enough, an effective coupling capacitance cannot be formed between the non-conductive pattern 112 and the screen surface of the capacitive touch screen, and a high frequency current on the screen surface of the capacitive touch screen cannot be changed, so that the touch screen cannot respond.
One or more conductive patterns 111 and non-conductive patterns 112 may be simultaneously provided on one pattern layer 11. The conductive patterns 111 and the non-conductive patterns 112 may be respectively disposed on different pattern layers 11. The conductive patterns 111 and the non-conductive patterns 112 have the same or similar colors.
Various methods may be used to determine that the colors of conductive patterns 111 and non-conductive patterns 112 are similar. For example, a first gray value of the color of the conductive pattern 111 is obtained, a second gray value of the color of the non-conductive pattern 112 is obtained, and if the difference between the first gray value and the second gray value is smaller than a preset difference threshold, it is determined that the colors of the conductive pattern 111 and the non-conductive pattern 112 are similar.
In one embodiment, conductive patterns 111 and non-conductive patterns 112 may be formed on the same pattern layer and in the same process, with the same or similar color. The conductive patterns 111 and the non-conductive patterns 112 may be sequentially formed on different pattern layers in the same or different processes, and have the same or different appearance colors. For example, the conductive pattern 111 is formed before the non-conductive pattern 112.
Conductive pattern 111 and non-conductive pattern 112 at least partially overlap, and non-conductive pattern 112 may also overlie conductive pattern 111. The transparency of the conductive pattern 111 in the visible light range is greater than a transparency threshold, which may be 10% transparency, or the like. For example, the conductive pattern 111 has a transparency of not less than 10% in the visible light range.
Conductive pattern 111 contains at least one conductive material comprising: at least one of metal powder, sheet metal, conductive carbon black, silver paste, nano silver, conductive polymer and two-dimensional conductive material. The conductive patterns and/or non-conductive patterns may be formed by printing, coating, spin coating, vapor deposition, etching, or the like. The non-conductive pattern 112 includes an insulating or semiconducting material, such as a non-metallic material, a printing ink, or the like.
In one embodiment, the conductive pattern 111 and the non-conductive pattern 112 are formed on the same pattern layer but have different colors by different processes, wherein the non-conductive pattern area is transparent photo-curing glue, a transparent pattern with grooves is formed on a transparent substrate after coating and nanoimprinting, the conductive pattern area is silver paste, the non-conductive pattern area is filled into the grooves in a coating or doctor-blading way after being formed, an opaque conductive pattern is formed in the grooves, and the transparency of the anti-counterfeiting element is still not less than the transparency threshold.
In one embodiment, the present disclosure provides a security article comprising a security element as in any one of the embodiments above. The security article is a foldable or crimpable security article including securities, documents, banknotes, etc.
Fig. 2 is a flow diagram of one embodiment of a method of detecting a security item according to the present disclosure, as shown in fig. 2:
step 201, collecting capacitance distribution change data of conductive patterns of the anti-counterfeiting element for the touch screen in a state that the anti-counterfeiting element of the security article is contacted with the touch screen; wherein the conductive pattern is capable of changing the capacitance distribution of the touch screen.
In one embodiment, the inspection standard information of the anti-counterfeiting element to be detected is stored in advance, and the contact information of the conductive pattern on the touch screen can be determined through the touch screen and by using the capacitance information. Partially folding and/or crimping the detected security article prior to detection; during detection, one or more pattern layers (areas) on the security article are pressed against the touch screen simultaneously or sequentially according to a detection method of the device prompt.
In the state where the security element is in contact with the touch screen, various methods can be used to obtain data regarding the change in capacitance distribution of the touch screen. For example, when the anti-counterfeiting element is in contact with the screen, only the area with the conductive image-text can generate current change at the corresponding contact position in the whole contact area, so that touch response is caused; the non-conductive areas do not respond as described above and therefore data of the change in capacitance of the contact locations can be recorded by the device for judgment.
The anti-counterfeiting element is flexible and curled, and the distribution and connection of the conductive patterns are determined according to the design. The detection method for the anti-counterfeiting element comprises the following steps: the finger does not directly press the screen; during detection, the two sides of the anti-counterfeiting element are held by hands, the anti-counterfeiting element is curled, and at least one position of a finger contacts with a part of the conductive image-text in the element, so that micro-current of a human body is conducted to a communication area of the whole conductive image-text; the curled anti-counterfeiting element is then contacted with the screen according to prompts given on the screen.
If the conductive patterns and texts of a plurality of conductive lines are required to be detected respectively, the device prompts in sequence, and the contact position of the finger and the anti-counterfeiting element or the contact pattern and text position of the anti-counterfeiting element with the screen are changed.
The touch screen can be set to be in an activated state capable of recording contact data, and response data of the conductive patterns acquired by the capacitive sensor on the touch screen, namely capacitance distribution change data of the conductive patterns on the touch screen, are acquired.
Step 202, determining contact information corresponding to the conductive pattern according to the capacitance distribution change data.
In one embodiment, in a state that the anti-counterfeiting element is in contact with the touch screen, the conductive patterns can change the capacitance distribution of the touch screen, the capacitance change can be caused, and the capacitance sensor acquires corresponding electric signals and converts the electric signals into contact information corresponding to the conductive patterns.
And 203, comparing the contact information with preset inspection standard information, and identifying the authenticity of the anti-counterfeiting element based on the comparison result.
In one embodiment, the conductive pattern characteristic data which the security article should have is stored in advance in the detection device with the touch screen as the inspection standard information. And comparing the collected contact information with the inspection standard information to identify the authenticity of the safety article.
The inspection standard information comprises standard pattern information, and the contact point information comprises detection pattern information corresponding to the conductive pattern; the standard pattern information and the detected pattern information include relative positions and distances between contacts, contact areas, change information of charge signal distribution, corresponding pressure value information, and the like. For example, the standard pattern information and the detected pattern information include information of relative positions and distances between different contacts, changes in current signal distribution, changes in charge signal distribution, pressure values, contact areas, and the like. If the detected pattern information is the same as the detected pattern information, determining that the anti-counterfeiting element is a true anti-counterfeiting element; and if the detected pattern information is different from the detected pattern information, determining that the anti-counterfeiting element is a pseudo anti-counterfeiting element.
Various methods can be used to obtain standard pattern information and to detect pattern information. For example, when a touch point signal is sensed, a screen of the capacitive touch screen can record coordinate values (x, y) of the touch point in the screen, so that the relative position and distance of each point can be calculated when a plurality of touch points are touched; information such as contact area can be calculated by acquiring basic data in the capacitive sensor, such as pixel coordinates and number of charge distribution changes, pressure value of the pressure sensor in the coordinates, and the like, through software.
When the verification is performed, detection prompt information for the anti-counterfeiting element is generated, and the detection prompt information can be displayed in a dialog box or other forms. The detection prompt information comprises: pressing multiple pattern layers of the anti-counterfeiting element on the touch screen simultaneously or sequentially. The user can contact the anti-counterfeiting element of the security article with the touch screen by adopting a corresponding method according to the detection prompt information displayed by the dialog box and the like.
As shown in fig. 3, the anti-counterfeiting element of the security article to be detected is pressed on the touch screen in an activated state by a finger, capacitance distribution change data of the touch screen can be read, distribution conditions of conductive patterns in the anti-counterfeiting element are calculated based on the capacitance distribution change data, and contact information of a finger area with a larger pressure value is removed, so that authenticity identification is performed. The calculation of the distribution of the conductive patterns in the security element may take a number of ways. For example, according to the number of contacts in the capacitive screen, the positions and the areas of the contacts, the trend of the conductive graphics in the area where the element contacts the screen can be drawn, similar to the trend of the current.
As shown in fig. 4, the anti-counterfeiting element of the security article to be detected is pressed on the touch screen in the activated state and slid, so that the capacitance distribution of the touch screen and the real-time change data of the contact area can be read, and the contact information of the finger area with a larger pressure value is removed, thereby calculating the distribution of the conductive patterns in the anti-counterfeiting element, and further performing the authentication.
As shown in fig. 5, after the security article to be detected is curled by a single hand, the anti-counterfeiting element is pressed on the touch screen in an activated state, capacitance distribution change data of the touch screen can be read, and the distribution situation of the conductive patterns in the anti-counterfeiting element is calculated based on the capacitance distribution change data, so that authenticity identification is performed.
As shown in fig. 6, two hands contact two ends of a security article to be detected, and the anti-counterfeiting element is pressed on the touch screen in an activated state, so that capacitance distribution change data of the touch screen can be read, and distribution of conductive patterns in the anti-counterfeiting element is calculated based on the capacitance distribution change data, so that authenticity identification is performed.
In one embodiment, as shown in fig. 7, the present disclosure provides an apparatus 50 for detecting a security article in any of the embodiments above, comprising: the system comprises a signal acquisition module 51, a data extraction module 52, a data processing module 53 and a detection prompt module 54.

After the conductive pattern changes the capacitance distribution of the touch screen, the signal acquisition module 51 continuously acquires the capacitance distribution change data of the area where the anti-counterfeiting element is in contact with the touch screen through the capacitance sensor, wherein the acquisition frequency is not less than a preset frequency, for example, 10 times, and the like.
The data extraction module 52 determines contact information corresponding to the conductive pattern based on the capacitance distribution change data. The data processing module 53 compares the contact information with preset inspection standard information, and identifies the authenticity of the anti-counterfeiting element based on the comparison result. The anti-counterfeiting element can be detected through a touch screen, a capacitive sensor and the like which are arranged in the detection equipment, and the authenticity identification can be carried out.
