METHOD AND COMPUTER SYSTEM FOR PROTECTING ELECTRONIC DOCUMENTS

摘要

Computer system (900) and method for protecting electronic documents. The computer system (900) includes a repository (903) for storing an electronic document (300) that has a document attribute (300-A). An access layer (902) is used (410) by an accessor (200) to access (460) at least one portion (300-1) of the electronic document (300). The accessor (200) has an accessor attribute (200-A). An expert system (904) is operable to determine an access behaviour with regards to the at least one portion (300-1) by evaluating rules of a rule set (800) with reference at least to the document attribute (300-A) and the accessor attribute when the accessor (200) tries to access the at least one portion (300-1) using (410) the access layer (902).
