Description

DETAILED DESCRIPTION OF THE INVENTION (aJ Technical Field of the Invention The present invention relates to a program maintenance method for preventing abuse of a registered program.

(b) Between the conventional technology and the system point processing system, log files (for example, for system development or application programs, etc.) exclusively for one person are recorded in the system in advance, and the log files can be used and recorded by the individual. Methods that have been adopted include inputting an already-used shobetsu code, or inputting an ID card with an omitted code.

In this conventional method, is there a sorting cord? Disadvantage 1: It is difficult to maintain the privacy of the program because it is easily used by others as it is a registered program only for one person.
cure

(C) Purpose of the invention The non-invention was made to solve the above drawbacks,
The purpose is to provide a nologram maintenance method that makes it easier to maintain the confidentiality of disappearance programs.

(d) @ Ming's 4 losses The present invention includes an ID card on which an identification code is distributed, a reader, a storage device for a registered program, and a processing device. Yo! In a system that also allows the use of a registration program corresponding to the identification code that has been taken, the registration program is encoded with 1LHf, and the 1LHf-encoded registration program is processed by a 4-reading processing program. When a card having a stored ID card is used and the card is inserted into the washing unit, the encrypted registration program kN ''JfJ record corresponding to the identification code of the ID card is This is a 4bR program protection system that allows the device to decode the processing program using the sound of the processing program in the ID card.

(e) Example of former first son The non-invention will be explained below with reference to drawings. The drawing is a block diagram illustrating an embodiment of the present invention, in which l is an ID card, 2 is a reading section, 3 is a floppy disk, 4 is a processing section, 5 is a memory, 6 is an output section, Ai, t) Save code for fυ, OU user code for A'I'i verification, C is conversion program, D is data, ■ is interpreter, L is loader,
M is a memory unique part, Po is a load program, Pl is a decryption processing program, NP2 is an encrypted registration program,
PS is the decoded registration program, S is the system identification code, S/ is the system identification code for verification, T is the table, and a, b, e, and f are the areas. The ID card 1 in the drawing has a storage section M (IC memory), in which a user code A1 data D1 and a load program P are stored.

, a decoding processing program P, and a system identification code S are stored. On the other hand, the encrypted registration program P2 and the user code A' for verification are stored in the Frosov disk 3, and the system identification code S/ for verification is stored in the area of the main memory 5. .

In the drawing, when an ID card 1 is inserted into a reading section 2, a load program PG in a storage section M is executed by a processing section 1. This load program P. II 1. A complete comparison of the system identification code S in the lower part M and the verification system identification code S' stored in the area S of the main memory 5;
Verify. When both match, load program P.

causes the decoding processing program PIk to be loaded into the area e of the main memory 5. Therefore, the m-reading processing Progera AP is executed by the processing unit 4, but the processing unit J@ is as follows. The user code A in the storage section M of the ID card 1 is compared with the verification user code A' in the floppy disk 3, and when the two match, the encrypted registration in the floppy disk 3 is Program P
2, and stores it in the area f of the main memory 5 while decoding it. This means that the decrypted registration program P4 has been loaded into the ff1jl area f. The decoding processing program P, as shown in area e of the main memory 5, is composed of a loader "s 亥j4J1 program C1 conversion table T".

In other words, the conversion program C uses Table 1 to decrypt the code.
This is done using ゛. Note that the decoding processing program P.

may have a built-in interpreter l.

The registration program P6 decoded through the above processing is executed by the processing section 4, and performs necessary processing on the data D in the memory section M of the ID card 1, for example. In the above embodiment, each program was executed by the processing section 4, but the ID card 1 may have a built-in processing section (1, converted to SI) described in 2, and use this to perform the processing on behalf of the ID card 1. You can also do that.

(f) More than the effect of the invention, the unexploited 8Atyu, 1;U Ministry of Finance dedicated registration program gold encryption, while this? ]l? By incorporating the decoding program into the ID card, there is an advantage that the registration program can be easily maintained.

4. The straight-cut drawing in Figure m1 is a block diagram floppy disk fully explaining an embodiment of the invention, 4ilS1. Processing section, 5 is main memory, 6 is output section, A is user code, A' is user code for verification, Ctri conversion program, D is data, ■ is interpreter, L is loader, M is storage section, P .

Claims (1)

[Claims] A registration program corresponding to the identification code, which comprises a card on which an identification code is recorded, a reading section, a storage device for a registration program, and a processing device, and is read by a custodian into the reading section of the card. 2, the registration program is encrypted, and a card is used that has a storage section in which a processing program for decoding the encrypted registration program is stored. Then, when the card is inserted into the Mf register* section, the biJ processing device uses the A11 processing program τ in the card to register the hσ Ilf encoded registration program corresponding to the card's identification code. A programmable maintenance method characterized by solving problems.
