JPS6024640A - Secret protecting device - Google Patents

Abstract

PURPOSE:To protect a secret of contents of a program by keying a program in a medium having a CPU, and limiting its use, copy, change, etc. CONSTITUTION:A card 1 is set to a card reader 5, and a password is keyed in from a keyboard 6. An operating part 3 is started by a control device 8, checks the password in a memory 4, and when it coincides a program 2 is opened. The program 2 is started as one body with a program 10 in the control device 8, and can be brought to access to the memory 4 and a memory 9. Information which is not contained in the memory 4 is stored in the memory 9. The program 2 is a program for outputting a question about a key word in the memories 4, 9 onto a CRT7. When the question is keyed in from the keyboard 6 and all coincide, the information is sent to a computer 11 and processed. In this way, the key word is dispersed to the card 1 side and the control device 8 side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to security of programs.

[Technical background of the invention and its problems]

Most of the ideas regarding confidentiality are originally related to data information, and restrictions on the use of software technology, especially the programs themselves, are not taken into consideration, giving rise to software copyright issues. This originally meant that the program itself could have a permit capability of 3% or 4%, or that a key could be attached to the program implementation medium.

Use, copying, modification, etc. of the program should be restricted. In the current OA boom, computer processing equipment has been introduced into every sector of human society, and the operators are becoming increasingly complex. Opportunities are increasing for such navigational procedures to be programmed and for various types of aesthetic works to be performed based on the input. In this case, if sufficient consideration is given to the confidentiality of the program, it can be applied to many more fields and can be streamlined.

[Purpose of the invention]

This invention was devised to meet the above-mentioned needs, and it is possible to key a program and copy it for use by an official.

This restricts changes, etc.

[Summary of the invention]

A program is installed in a medium such as a card or chip that has a CPU, and the program is only released after checking permissions.

A program is implemented on a medium with a control mechanism to ensure confidentiality.

〔Effect of the invention〕

Since permissions can be set for each program, software copyrights are protected and copying is prevented. Furthermore, it will not be used by others without permission.

Furthermore, this program itself can be used as some kind of key, and in that case, the program contents can be kept secret.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In Figure 1, 1 is the card base, and inside the card,
Psigram mounting section 2. A chip consisting of 4 memory parts and 3 CPUs is embedded. Memory part 4 stores other keywords including the Omo ID number.

For example, enter the person's name, date of birth, family name, etc.

The card 1 is set in the card reader 5 shown in FIG. 2, and a password is entered from the keyboard 6. Card calculation section 3
is activated by the control device 8 and checks the password, etc. in the memory 4 and the key-in number. This can be done on either the card 1 side or the control device 8 side. Various checks are performed, such as providing a function to identify the other party on both the card 1 side and the control device 8 side, and if they all match, the card 1 side The calculation unit 3 on the side opens the program 2 in the card. There are two ways to open the card: to allow the control device 8 to access the program 2 and memory 4 in the card, or to load the program 8 together with the memory contents into the control device 8. The program 2 is started integrally with the program 10 in the control device 8. The integrated program can access the memory 4 of the card 1 and the memory 9 on the control device 8 side. The memory 9 stores information not included in the memory 4, such as address and occupation name. Program 2 is a program that outputs questions about keywords in memory 4 and memory 9 onto CRT 7. The answers to these questions are keyed in from the keyboard 6.

If all match, the information is sent to the computer processing device 1.
1 to perform the sending process. If the program 2 has been loaded into the control device 81, the program 2 either erases itself or the calculation unit 3 does it.

By creating this system, the keywords are distributed on the card 1 side and the control device 8 side (:), and the program that checks them is also distributed, so information leakage due to card loss, Fraud on the part of the control device can also be prevented.The feature of this system is that by keeping the program contents secret, it guarantees safety even if the data is known.

[Other embodiments of the invention]

This invention is not limited only to the above embodiments, but can be widely used. For example, if you are selling a certain piece of software, you can make it so that only a specific key can be used to access the program on the card, so that it will not be copied. Also, processes that require secrecy, such as I
It is also possible to program the CJL manufacturing process and load the program with a key to perform precise control and data collection.
