Abstract

PURPOSE:To evade a defect in matching between programs due to the diversion of a program from a different system by registering information required for program can protection and program contents. CONSTITUTION:A user inputs the information on a manufacture date, a manufacture number, a program name, etc., required for the call protection of the program and the program contents and they are registered in an auxiliary storage device 6 by a registering means 2. Then the user operates a program loading means 3 through the input means 1 and then the loading means 3 inputs the registered information on the manufacture data, manufacture number, program name, etc., and program contents from the auxiliary storage device 6 and sends the manufacture number and manufacture date to a deciding means 4. the deciding means 4 decides whether or not a system can execute the program from the information on the manufacture number and manufacture date and displays abnormality on a display means 7 when not, thereby finishing the processing. When it is possible, a program starting means 5 is put in operation to start the execution of the program.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program call protection system, and more particularly to a program call protection system that is a component of a software system.

[Conventional technology]

Conventionally, this type of program call protection system has been a system in which a hardware mechanism having a key for protecting a program or a group of programs and the program or group of programs to be protected are integrated to protect the program.

[Problem that the invention seeks to solve]

The conventional program call protection method described above was a method that protected the program as an integral part of the hardware mechanism, so instead of protecting individual programs,
This system protects a group of programs constituting one function, and as a result, there is a drawback that consistency between programs may be lost if some programs are diverted from other systems.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a program call protection system that makes it possible to avoid inconsistency between programs due to partial program diversion from another system.

[Means for solving problems]

The program call protection system of the present invention includes a registration means for registering information necessary for program call protection and program contents in an auxiliary storage device, and information and programs necessary for program call protection registered by the registration means. It has a program loading means for inputting contents from the auxiliary storage device, and a determining means for determining whether or not the program can be executed based on information input by the program loading means necessary for protecting the program from being called.

[Effect]

In the program call protection method of the present invention, the registration means registers information necessary for program call protection and program contents in an auxiliary storage device, and the program load means registers information necessary for program call protection registered by the registration means. and the program contents are input from the auxiliary storage device, and the determining means determines whether or not the program can be executed based on information necessary for protecting the program call manually input by the program loading means.

〔Example〕

Referring to FIG. 1, one embodiment of the present invention includes an input means 1
, a registration means 2, a program loading means 3, a determining means 4, a program starting means 5, an auxiliary storage device 6,
It is composed of a display means 7.

Referring to FIG. 2, the processing in the registration means 2 consists of a program information input step 21 and a program information storage step 22.

Referring to FIG. 3, the processing in the program loading means 3 consists of a registration information manual step 31 and a determining means activation step 32.

Referring to FIG. 4, the processing in the determining means 4 consists of a normality determining step 41, a program starting means starting step 42, and an abnormality notification step 43.

Next, the operation of the program call protection system of this embodiment configured as described above will be explained.

The user inputs information such as manufacturing date, serial number, program name, etc. and program contents necessary for program call protection through the input means 1, and operates the registration means 2.

The registration means 2 manually enters this information in a program information input step 21 and registers it in the auxiliary storage device 6 in a program information storage step 22.

Next, the user operates the program loading means 3 while using the input means 1.

The program loading means 3 is the registration information manual step 31
The registered manufacturing date, serial number, and
Enter information such as program name and program content,
Among the information input in the determination means activation step 32, the serial number and manufacturing date are sent to the determination means 4, and the determination means 4 is activated.

The determining means 4 determines whether it is normal in the normal determining step 41? ! It is determined whether the model number and manufacturing date are normal or not, that is, whether the program can be executed on the system or not. If the system is abnormal, the abnormality is displayed on the display means 7 in an abnormality notification step 43. Finish the process. If normal, the program starting means 5 is started in a program starting means starting step 42 to start execution of the program.

〔Effect of the invention〕

As explained above, by providing a registration means, a program loading means, and a determination means, the present invention makes it possible to confirm whether or not a program can be used in a particular system before executing the program, and to reuse part of a program from another system. This has the effect of avoiding inconsistencies between programs due to this.
