Description

Description: TECHNICAL FIELD The present invention relates to a plate-shaped storage medium suitable for collectively storing various types of information about an individual.

(Prior Art) Since a plate-shaped storage medium such as an IC card used for personal authentication such as a credit card or a cash card can have a large storage capacity without inviting an increase in size, it is simply an individual. Not only for authentication but also for health management information, financial information, family register information, etc. are stored comprehensively, and a plan to make daily life possible with one plate storage medium is emerging.

However, conventionally, such a plate-shaped storage medium is provided with only one personal identification code known only to the owner, so that even unintended information can be read, which may lead to invasion of privacy. There is

(Purpose) The present invention has been made in view of such circumstances, and an object of the present invention is to provide an independent personal identification code for each piece of information in order to prevent access to information other than the intended one. Therefore, it is an object of the present invention to provide a plate-shaped storage medium for recording personal information that can protect privacy.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

FIG. 3 shows an embodiment of the present invention, in which reference numeral 1 is a plate-shaped storage medium according to the present invention, which is used for inputting a personal identification code on the surface of a substrate having a signal processing unit described later. The key board 2, the display device 3 for displaying the collation result, the power switch 4, and the contact pins 5a to 5h for external connection are arranged and mounted in the card insertion port C of the read / write device R to perform data communication. Is configured to be possible. In addition, reference numerals A and B in the drawing denote a keyboard and a display of the read / write device R, respectively.

FIG. 1 shows an embodiment of a signal processing circuit unit in a plate-shaped storage medium. In FIG.

(Hereinafter, referred to as an interface), which is initialized by a reset signal input from the contact pin 5b, and then, by a timing signal from the contact pin 5c, a data storage unit 20 and a read / write device described later via the contact pin 5d. It enables communication with R. Reference numeral 20 denotes the above-mentioned data storage unit, which is an electrically rewritable semiconductor memory circuit (hereinafter referred to as EEPROM) 22.
And EEPROM control circuit 21. This EEPROM 20 is
As shown in FIG. 4, the independent addresses I, II, III ...
Are allocated to a plurality of information storage areas 22a, 22b,
.., and is configured to be able to read and write only the data in the storage area that matches the address input via the data management unit 10.
Reference numeral 30 is a personal identification code storage means, which is an individual identification code storage area 30 for identifying an individual as shown in FIG.
a, storage areas 22a and 22b of the data storage unit 20,
22c ... A plurality of content-specific code storage areas 30b, 30c for storing content codes for specifying each of
It is divided into 30d ... And outputs the stored contents in response to a read command from the data management unit 10. Reference numeral 40 is a code collating unit, which is composed of a code judging means 41, a content-specific movable signal output means 42, and a clocking means 43. The code determination means 41 compares the data from the keyboard 2 with each code in the code storage means 30 and outputs a match signal when they match. The content-specific movable signal output means 42 receives the coincidence signal from the code determination means 41,
For example, the storage areas 22a, 22b, and 22c of the codes for which a match is confirmed by activating the interface 14
While outputting a signal for enabling access to ..., It outputs a signal for inactivating due to a time-up signal from a timing means 43 or a communication end signal from the read / write device R described later. The time counting means 43 has a time T sufficient for inputting the individual identification code into the plate-shaped storage medium and then inputting the content-specific code.
₁ and the time T ₂ required for mounting the plate-shaped storage medium on the read / write device R are set in advance, and start the time counting operation upon receipt of the personal code coincidence signal or each content-specific movable signal, The time-up signal is output when the times T ₁ and T ₂ have passed, while the time counting operation is interrupted when the communication signal from the read / write device is received. Each of these means 10, 20,
The operating voltage supply terminals of the batteries 30 and 40 are supplied with the operating voltage from the built-in battery 50 via the switch 4.
Reference numeral 51 in the figure indicates a driver that outputs the collation result of the code to the display device 3.

Next, the operation of the apparatus thus configured will be described based on the flow chart shown in FIG.

For example, when the power switch 4 of the plate-shaped storage medium 1 (FIG. 1) is turned on in order to deposit or withdraw a deposit, the plate-shaped storage medium 1 becomes operable.

When the personal identification code is input from the keyboard 2 at this stage, the data management unit 10 reads the personal identification code stored in the recitation code storage unit 30 to the code collating unit 40. The code determining means 41 compares the personal identification code from the keyboard 2 with the personal identification code from the personal identification code storage means 30 and outputs a coincidence signal when the two coincide. As a result, since it is confirmed that the storage medium is owned by the person in question, the content-specific movable signal output means 42 receives the coincidence signal and operates the clock means 43 to start clocking. In such a state, time T
Before ₁ passes, the owner issues a code for each content on the keyboard 2
When input from, the code judging means 41 compares this content-specific code with a plurality of content-specific codes stored in the secret code storage means 30, and sends the content-specific code to the address of the data storage section 20 corresponding to the matched content-specific code. The access is made possible, and at the same time, the time counting means 43 is reset and the time counting operation is started again. In this state, if the plate-shaped storage medium 1 is mounted on the read / write device R (FIG. 3) before the time T ₂ has elapsed, the plate-shaped storage medium 1 does not have a code input from the read / write device R and the data is read. Communication is possible. As a result, the read / write device R starts communication with only the data designated by the content-specific code among the plurality of data in the data storage unit 20 of the plate-shaped storage medium 1, and at the same time transmits the communication signal to the plate-shaped storage medium. Output to 1. The clock means 43 receives this communication signal and stops the clock operation.

When the reading and writing of the necessary data are completed, the communication end signal is output from the read / write device R, and the content-specific movable signal output means 42 receives the communication end signal and disables the interface 14 in the operating state. It is activated to prevent subsequent data reading.

It should be noted that after the personal identification code is input, it takes time to input the content-specific code, and time T ₁ elapses, or it takes time to input the content-specific code and attach it to the read / write device R, the time T ₂ elapses. Then, when the time measuring means 43 has timed up, the content-specific movable signal output means 42 becomes the time measuring means 4.
Received the time-up signal from 3 and became inoperable,
Prevent unauthorized use.

On the other hand, when the read / write device R is at hand,
The data specified by the content-specific code can be obtained by directly mounting the read / write device R without inputting the personal identification code from the keyboard 2, inputting the personal code from the keyboard A, and then inputting the content-specific code. If possible to access.

In this embodiment, the code input means 2 is provided in the plate-shaped storage medium. However, even if the code input means 2 is not provided, by inputting the personal identification code and the content-specific code from the read / write device, Obviously, only certain memory contents can be accessed.

(Effect) As described above, in the present invention, a personal identification code for identifying an individual and a secret code storage means for storing a plurality of content-specific codes for identifying each of a plurality of information storage areas, and , Secret code input means, collating means for judging whether the inputted secret code and the code of the secret code storing means coincide with each other, and outputting a coincidence signal when they coincide, and storing information corresponding to the content-specific code The information storage means having a plurality of information storage areas and the matching means based on the collation of the individual identification code are output from the collating means, and the time counting operation is started. Since it is equipped with a means to deny access to the information storage means when it is not output,
Personal information can be managed by the double barriers of confirming the authentic owner of the plate-shaped storage medium and presence / absence of an access right to specific information among a plurality of types of information.
