Abstract

PURPOSE:To simplify an operation method and execute checking of an access right for every file by determining an execution program on a basis of a code set to label information of every file and an input code. CONSTITUTION:An information processing part 13 starts an access part on a basis of 'the name of a file to be processed', which an operator 17 designates to an input part 12, and reads out label information having the same name as the designated file name from a label information area 20 of a data/program information file part 16 and sets this information to a label information buffer 24 of a data storage area 22 in a storage part 14. 'A code' indicating the internal data classification of the file 16 to be processed is set in label information of this file 16 and is discriminated by the designated file name to determine a program which processes the designated file. Thus, the operator 17 designates only the file to be processed to execute a desired processing, and the operation is simplified.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a processing program specification method, and in particular, it facilitates an operator's specification of a file for a processing device that processes various types of information, and at the same time protects the security of the file. This invention relates to a processing program designation method suitable for making the process more reliable.

[Background of the invention]

For example, in an information processing device that processes ``calculation'', ``graphical display'', ``data collection'', etc., the timing to execute the processing is when the program file corresponding to each of the above processing contents is specified by the operator etc. It is.

One of the file designations by the operator is the ``menu selection method.'' That is, this is a method in which a menu of programs and the like is displayed on a display, and one of the programs is selected and executed using a light pen, keyboard, or the like.

In this method, the operator generally makes an initial menu selection, then displays a new menu to implement the selected menu, and then requests the operator to select that menu, and so on. The operator also had to remember the name of the program for processing. However, since the operator is clearly aware of the name of the file or document that he or she handles, it is a heavy burden to be aware of even the name of the processing program. Note that related methods of this type include, for example, Japanese Unexamined Patent Application Publication No. 1987-
Publication No. 30073 can be cited.

In addition, with the recent spread of terminal devices, files on information processing devices can be easily updated, so it is necessary to protect the IavFi of files with high importance. There is a ``file security system'' described in Japanese Patent No. 17650/1983.

The above-mentioned method increases confidentiality by determining a type code using a personal identification code from an operator and an identification code from a card, and accessing files based on the type code.

However, in this method, a card reader for reading cards is required in the system, and it is necessary to classify files by type code into combinations of multiple files.

[Purpose of the invention]

An object of the present invention is to solve such conventional problems, and to provide an information processing apparatus that has various files and executes program processing based on the files, by a simple and inexpensive method. It is an object of the present invention to provide a processing program designation method that can simplify the method and check the access right to each file.

[Summary of the invention]

In order to achieve the above object, 1 the processing program designation method of the present invention is provided for each of the above files (A, B,...) in an information processing apparatus that has various files and executes program processing based on the files. Label information (26,
46) is provided with a code that can be set in advance (type code 36, access right check code 56), and the program to be executed is determined based on the code and another input code, or the presence or absence of file access right is determined. There is a characteristic in doing.

9 reads the file (file A) with the above processing program name stored therein, sets it in the text storage area 21 of the storage section 14, and executes processing based on the program (step 104).

In this way, the ``type code'' 36 indicating the internal data type of the file is set in the label information 26 of the program file to be processed, and it is identified by the specified file name, and the specified file is processed. Since the program for
Specified processing can be executed. As a result, the operator 17 can simply specify the file he or she wants to process, and can omit directly inputting the name of the processing program required to carry out the process. Can be provided.

It is.

In FIG. 4, 11 is an information processing device.

Input section 12 similar to the first embodiment. Information processing unit 13° storage unit 14. It consists of a data file section 41 in addition to the file access section 15. Note that the input section 12. Information processing section 13. Storage unit 14. The file access unit 15 has a table storage area 23 and a data storage area 22, each of which accepts an operation 18 from an operator 17 and processes information as a whole of the device using a method described later, as in the first embodiment.
A data storage area 23 between the storage section 14 and the data file section 41. In the data storage area 22, there are user/access right check code correspondence tables 44, details of which will be described later. A label information buffer 24 is provided.

The data file unit 41 stores various files for processing in a data storage area 42 and a label information area 43.

The data file section 41 is configured as shown in FIG. In the label information area 43, the label information 46 of each file in the data storage area 42 is displayed for each file, as shown in the figure.
．． 'Block length' 48, Lou code length '49. 'Start address' so, 'End address' 51. 'Last record address' 52, 'Creation date and time' 53. 'Storage period' 54
．． The following items are stored: ``Owned pitch name'' 55 and ``Access right check code'' 56. Note that 'start address position 0', 'end address' 51. 'Final record address' 52 is set to →, ←m, ← respectively in the data storage area 42 as shown in (file A), as in the first embodiment.
This is the address position of Q.

Next, file security processing according to the present invention will be described with reference to FIGS. 4 to 6.

The information processing section 13 inputs the input section 1 when the operator 17 starts the operation.
By receiving the operator's own ``user code'' input in step 2 and the ``access right check code'' for the file to be used from now on, these are registered in the user/access right check code correspondence table 44 (step 111).

Note that the ``access right check code'' to be input is a code that has been set in advance.

Therefore, now the 'user code' of operator 17 is rU
SRJ, the name of the file used by operator 17 is "A"
, if the 'access right check code' 56 for the file rAJ is set as rl122, the operator 17 enters the user code rU in the input section 12 at the time of start.
SRJ and access right check code rl122J
Perform operation 18.

Next, the information processing unit 13 executes the processing program for the file rAJ ((file A) in the data storage area 42) specified by the operator 17, and at the same time opens the file (file A) (grants access rights to the file A). (behavior to establish).

In other words, the information processing unit 103
, reads the label information 46 of file A from the label information area 43 of the data file section 41, sets it in the label information buffer 24 of the data storage area 22 of the storage section 14, and executes the 'access right check'. Obtain the content rl122J of the code '56 (step 112)
.

Subsequently, the information processing unit 13 that recognized the contents of the 'access right check code' 56 inputs the user code rUSRJ from the operator 17 into the user/access right check code correspondence table 44 registered above. After searching the key and obtaining the contents of the access right check code rl122J that the operator 17 inputted at the start of the operation, the contents of that code and the contents set in the ``access right check code'' 56 of the label information 46 are obtained. If they match, it is determined that the operator 17 has access rights to file A. If there is a mismatch, access to important files will be disabled.

In the above, the embodiment was explained focusing on file A, but
In reality, access rights are checked each time each file is opened. Furthermore, the 'access privilege check code' that the operator 17 inputs at the start of the operation can specify multiple files.In other words, instead of inputting these codes in association with each file, Can be used with common checking code.

In this way, the 'user code' and 'access right check code' from the operator are stored, and the 'access right check code' and the 'access right set in the label information field 46 of the designated file are stored. Check tears code′
56 to check whether the operator 17 has the right to access the specified file. Access rights can be checked for each unit.

Furthermore, since the ``access right check code'' 56 is set for each file, detailed access right operations can be realized. ■Just by updating the 'Access rights check code' 56 of the label information 46 of each file as appropriate.
File protection features can be updated. ■The owner of each file can transfer file access rights simply by teaching the ``access right check code'' of that file to another person.

[Effects of the Invention] As explained above, according to the present invention, in an information processing apparatus that has various files and executes program processing based on the files, a 'type code' provided in the label information of each of the files is used. Since the specified file name is extracted and the corresponding processing program is determined, the operator only has to specify the file he or she wants to process, making the operation method simple. On the other hand, in the same way as above, the 'access rights check code' provided in the label information is searched for with the specified file name, and the access rights to the specified file are checked by comparing it with the access code specified at the same time. , it becomes possible to check file by file.
