[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a pad issuing apparatus and a method for providing a pad with an intelligent pad with a protection function so that useful information such as expiration date cannot be rewritten.

[0002]

2. Description of the Related Art One of programs on a Web server on the Internet is called an intelligent pad. Intelligent Pad is a program technology researched and developed by Professor Joe Tanaka, Faculty of Engineering, Hokkaido University. The intelligent pad technology will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the concept of an intelligent pad. As shown in FIG. 1, the system includes a base pad 10 representing the entire intelligent pad, various pads 12 which are units of a program, and a combining pad 14 which can combine the pads to create an execution program. In this example, the various pads 12 include a text pad 12-1 for creating a word processing sentence, a graph pad 12-2 for creating a graph, and an image pad 12-3 capable of capturing an image, and can perform calculations. And a calculation pad 12-4. A pad is a block of a program created by object-oriented programming technology. Pads can be thought of as puzzle pieces. In other words, the user can create a program suitable for the purpose of use by combining and removing pieces as if playing a puzzle.

A user downloads the base pad 10 from a web server. The base pad 10
It is displayed on the display of the terminal device as shown in FIG.
The user drags and drops the text pad 12-1 on the synthesis pad using a pointing device. Graph pad 12-2, image pad 12-
3, the calculation pad 12-4 is similarly operated. Synthetic pad 14
The synthesized pad created above can be used as word processing software. Further, for example, the image pad 12-
If 3 is unnecessary, the function can be performed by dragging and dropping from the synthesis pad 14. That is, the user can freely build a target program by adding or deleting pads having various functions by a simple operation.

In a web server on the Internet,
Various programs are provided to users for a fee / free of charge. If the expiration date of a program provided for a fixed period of time is used, the program can no longer be used. However, a limited number of users rewrite the expiration date of the program or rewrite the data of the program. As a means for preventing such rewriting, a function of protecting a property file attribute is used. Alternatively, measures such as providing a program for protection in the program itself are taken. The same applies to intelligent pads.

[0005]

When a pad used for an intelligent pad is distributed on the WWW, the WEB is used.
In a method in which a user downloads pad data or a pad library placed on a server, data that changes every time, such as user information and a serial number, cannot be set. Also, only the pad issuer can set the protection attribute, which cannot be changed by the user.However, depending on the difference in the pad operation environment, the slot information may be erased in an unintended place or may be set by a malicious user. The information may be rewritten. In such a case, there has been a demand for enhanced security of pad data.

SUMMARY OF THE INVENTION An object of the present invention is to provide a WEB in an intelligent pad capable of protecting information in a slot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. FIG. 2 is a block diagram showing a pad issuing device according to the present invention. The apparatus of the present invention comprises a web server 16 accessible using internet browsing software;
And a server extension program 18 stored in the web server. The device of the present invention is connected to the user terminal device 20 by a communication line. The server extension program 18 includes an input / output unit 22 for transferring information sent from the user and a created pad, and a management unit 24 for managing information from the user and issuing records of the pad.
A pad creation unit 26 for creating a pad and setting user information from the management unit 24; a server pad library 28 for an administrator to read and rewrite all information of the pad; and a user distribution pad library 30 It is composed of The communication between the user and the web server is
Uses the HTTP protocol. The input / output unit 22, the management unit 24, and the pad creation unit 26 are realized by a program.

The pad here includes pad data and a pad library. The pad data is information unique to the pad, such as coordinates, size, and other data. The pad library implements pad functions such as performing a specific calculation by incorporating pad data and changing data. The pad library can function without pad data and generate pad data. Further, the pad library has a function for calling data of information such as the expiration date of the slot, but the function of the pad library distributed to the user is only for calling. This function passes the data in the slot to the user when the user accesses the slot, but if the user attempts to write to the slot, there is no factor that passes the data that the user wants to input from the user to the slot. It is. In other words, with this function, the information flow is a one-way traffic in which the slot information flows to the user, and the user can refer to the information such as the expiration date stored in the slot, Writing is not possible. For example, even if a malicious user attempts to rewrite the expiration date, this function will not be able to do so.

A pad library for a server has no functional restrictions. In other words, the server pad library uses functions that allow information to flow back and forth. However, the server pad library can be written by an administrator, but cannot be accessed by a user in the server.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIG. FIG. 3 is a flowchart until the user acquires a pad. The user is the terminal device 2
From 0, the user accesses the WEB server using Internet browsing software (step A1). WEB server 1
6 forwards the required entry form to the user who has accessed to obtain the user information (step A
2). The form for filling in the required items is a password, address,
Enter your name, telephone number, etc.
This is an L format file. The user fills out the transferred required form on the terminal device 20 and transmits the completed required form to the WEB server (step A3). The WEB server checks whether the user information transferred from the user is appropriate or not.
4 is compared with the information stored in step S4 (step A4). The comparison in this case is to determine whether the member is a registered member and whether the format is correct. If it is determined that the compared information is not correct, an error message is returned to the user, an error is recorded in the management unit 24 (step A5), and the process ends. If it is determined that the compared information is correct, the process proceeds to step A6. W
The EB server receives the required item entry form filled in by the user information at the input / output unit 22 of the server extension program 18. The server extension program 18 extracts the user information from the required item entry form filled in by the transferred user information and stores it in the management unit 24. The stored user information is stored in the management unit 2 as information specific to the user together with the password, the expiration date, and the ID assigned by the management unit 24.
4 (step A6). At the same time, it instructs the pad creation unit 26 to create a pad. Pad creator 26
Acquires the information specialized for the user from the management unit 24, acquires the pad from the server pad library 28, and starts creating the pad (step A7). Pad creator 2
6 writes information specific to the user in a slot that is a property of the pad. Since the pad distributed to the user has a function having only a factor for passing data from the slot to the user side, it is possible to refer to information in the slot by having information specific to the user in the slot. , Information such as the expiration date cannot be rewritten. The pad creation unit 26 passes the pad in which the information specific to the user has been written to the slot to the input / output unit 22,
The input / output unit 22 receives the pad library of the user-distributed pad library 30, and transfers to the user a pad in which information specific to the user passed from the pad library and the pad creating unit 26 is written in the slot (step A8). . The server extension program 18 determines whether the pad has been normally transferred (step A9). If the transfer is not successful, an error message is returned to the user, and the message is recorded in the management unit 24 and the process is terminated (step A5). If the transfer is successful, the pad issuance history is registered in the management unit 24 (step A10), and the process ends.

When the user receives the pad library, the pad, and the password from the web server, the user can use the pad by inputting the password when using the pad. The pad library manages information such as a write-protection attribute and a trial period for the slot. The pad library checks the date each time the user uses the pad, and can use the pad if it is within the expiration date from the issued date of the issued pad, but cannot use the pad after the expiration date. The user can refer to the expiration date of the pad, but cannot rewrite it.

[0015]

According to the present invention, since the pad library distributed to the user manages information such as the write-protection attribute for the slot and the trial period, the information is not rewritten by the user, and the security for the pad is enhanced.

Also, the administrator can issue the pads all at once on the WEB server side, thereby managing the issue of which pad was issued to whom and the information management such as user information, trial period, and serial number. Can be easily and automatically performed.
