Abstract
Abstract 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
(1) A computer network connected with a plurality of computer systems through a communication medium for accessing files that said plurality of computer systems have from all of said plurality of computer systems, each of said plurality of computer systems comprising: access authority information storage means for storing information with respect to access authority in accordance with an owner ID; means for determining whether or not a format of said user ID and said access authority being received accord with a format of own user ID and own access authority when a remote access is accepted; means for converting the format of said user ID and said access authority being received into the format of own user ID and own access authority in accordance with a predetermined conversion rule when the format of own user ID and access authority is not matched with the format of said user ID and said access authority being received. means for comparing said user ID and said access authority whose format has been converted with information of said access authority stored in said access authority storage means and for determining whether or not to execute said remote access.
Claim 2
Dependent Claim
253 words
(2) A computer network connected with a plurality of computer systems through a communication medium for accessing files that said plurality of computer systems have from all of said plurality of computer systems, each of said plurality of computer systems comprising: access authority information storage means for storing information with respect to access authority in accordance with an owner ID; means for adding a machine ID to a user ID and for sending the resultant ID to another computer system of said plurality of computer systems when a remote accest request is issued; means for determining whether or not a format of said user ID and said access authority being received accord with a format of own user ID and own access authority when a remote access is accepted; conversion rule storage means for storing a rule for converting a format of said user ID and said access authority; means for converting the format of said user ID and said access authority being received into the format of own user ID and access authority in accordance with a conversion rule stored in said conversion rule storage means when the format of own user ID and access authority is not matched with the format of said user ID and said access authority being received; and means for comparing said user ID and said access authority whose format hat been converted with information of said access authority stored in said access authority storage means and for determining whether or not to execute said remote access.
Claim 3
Dependent Claim
52 words
(3) The computer network as set forth in claim 1, wherein each of said plurality of computer systems further comprises means for determining whether or not a file with respect to an access request is present in own computer system and for requesting a remote access when the file is not present.
Claim 4
Dependent Claim
52 words
(4) The computer network as set forth in claim 2, wherein each of said plurality of computer systems further comprises means for determining whether or not a file with respect to an access request is present in own computer system and for requesting a remote access when the file is not present.
