A method and system for managing the electronic signing of digital documents is disclosed. An electronic document created and prepared for signing by associating certain signing constraints with the document. Indicia of the signing constraints are encoded into a document information block or blocks that are embedded into the document. The information block may include indicia of a database record at a central server that stores indicia of the signing constraints in addition to or in lieu of including the signing constraint indicia in the document information block or blocks. Upon receiving the prepared document at a signing terminal, the information blocks are extracted and the signing constraints tested. If the user desires to sign the document, and if the user is permitted to sign, the document is electronically signed and transmitted to the central file server for storage.

A server in a digital rights management system implements version control for the digital documents being managed. Each document belongs to a document series and has a version number. The server maintains a version control database table that stores, for each document, the document series name and version number, and parameters indicating whether the document is obsoleted or deleted. When registering a new document, based on auto-obsolete and auto-delete parameters inputted by the user, the server automatically obsoletes or deletes certain older version documents that belong to the same series as the new document. The server controls access to the documents so that obsoleted documents will not be accessible to users even if they still have local copies of such documents. When a user requests access to an older version document that is not obsoleted, the server may allow access to the latest version document instead.
