Secured document access control using recipient lists |
摘要 |
A method for providing secured access to a document includes the steps of embedding a permissions attribute into a recipient list. The permissions attribute identifies permissions allowing various levels of access to a predetermined document. Each recipient listed in the recipient list has a corresponding permission associated therewith. Further, the method renders the recipient list and its contents tamper-proof.
