초록 ▼

Each computer system of the computer network according to the present invention has a management information storage portion for storing information with respect to an access authority in accordance with an owner ID and a conversion rule storage portion for storing a rule for converting the formats of a user ID and an access authority. Each computer system adds a machine ID to a user ID and sends the resultant ID to another computer system when a remote access request is issued. In addition, the computer system determines whether or not the formats of the user ID and the access authority being received accord with those of a local computer system when a remote access is accepted. The computer system converts the formats of the user ID and the access authority being received into those of the local computer system in accordance with a predetermined conversion rule when the formats of the local computer system are not matched with those on the remote computer system. Thereafter, the computer system compares the user ID and the access authority whose formats have been converted with information of the access authority stored in the access authority storage portion and determines whether or not to execute the remote access.

대표청구항 ▼

A computer network, where a plurality of computer systems are connected through a communication medium, each computer system being capable of accessing files of another computer system, each computer system being given a specific machine ID, each computer system having set kinds of file operations per file, each file being given a specific file ID, and a format of the file ID being set per computer system, comprising: a computer system accessing the file, including means for adding the machine ID to the file ID of the requested file when access to the file of another computer system is requested; and means for sending the file ID and the added machine ID to the other computer system; and a computer system whose the file is accessed, including a first table storing correspondence relationships between the kinds of file operations in the computer accessing the file, and the kinds of file operations in the computer whose the file is accessed; a second table storing correspondence relationships between the format of the file ID in the computer accessing the file, and the format of the file ID in the computer whose the file is accessed; a third table storing the file ID and the kinds of capable operations per file; means for receiving the file ID and the added machine ID from the computer system accessing the file; means for discriminating the computer system whose file is accessed based on the machine ID received by the receiving means; first determination means for determining whether the kinds of file operations of the discriminated computer system coincide with the kinds of file operations of the computer system whose file is accessed; first conversion means for, when the kinds of the two computer systems do not coincide with each other, converting the kinds of file operations system to the kinds of file operations of the computer system whose file is accessed in accordance with the first table; second determination means for determining whether the format of the file ID of the discriminated computer system coincides with the format of the file ID of the computer system whose file is accessed; second conversion means for, when the formats of the two computer systems do not coincide with each other, converting the format of the file ID system to the format of the file ID of the computer system whose file is accessed in accordance with the second table; and means for judging whether the requested access is allowed based on comparison of the converted file ID and the converted kinds of file operations with the file ID and the kinds of file operation stored int eh third table.
