<P>PROBLEM TO BE SOLVED: To easily execute the setting, operation and correction of an access limit to a document of HMTL format. <P>SOLUTION: When terminal devices 31-33 access to document data 61-63, an authority confirmation part 52 acquires the access authority of an access source in reference to a database 20, and an invalidating processing part 53 converts the address of a link destination designated by a tag in the document data 51-53 to invalidate it. A cancellation processing part 54 compares the access authority confirmed by the authority confirmation part 52 with a security level set in the document data, and permits the display of a link destination document by cancelling the invalidating processing of the link destination with a security level less than the access authority. <P>COPYRIGHT: (C)2004,JPO |
