ABSTRACT:
A method is disclosed for retaining access to deleted documents in a data processing system. In a data processing system multiple documents may be stored and accessed by a plurality of users. Each user may be authorized a particular access authority to a document which limits the activities that user may undertake with regard to that document. In accordance with the method of the present invention any user having access authority to a document may designate that document as a retained document. Thereafter, any attempted deletion of that document by the owner thereof will result in the retention of the document for those users who have designated it as a retained document. Further, any attempted alteration of the user's access authority for that document which results in a denial of future access will result in the automatic creation of a copy of that document with the user's original access authority. In this manner a user, having once been granted access authority to a document, may elect to designate that document as a retained document and thereby assure continued access to that document despite an attempted deletion of the document or an alteration of the user's access authority.
