Abstract: With the development of computer network technology, the extent of resource share has been enlarged, which brings the security problems in the information system. That ensuring electronic document security in the system is the key to prevent the secret of the information system. The UCONABC model is comprehensive enough to encompass traditional access control and modern access control. An electronic document security system based on UCONABC model is designed and implemented, and the electronic document security mechanism, system framework and its key techniques are discussed.

Key words: UCONABC model, electronic document security system, reference monitor
