Abstract

An improved file security system that manages secured files (documents) is disclosed. The file security system provides centralized management and storage of security information that can be referenced by secured files. In other words, a secured file need not itself contain security information that is needed to determine whether access to the secured file is to be permitted. That is, at least a portion of the security information can be remotely stored and accessed by way of an identifier that is provided within the secured file. By centralizing storage of security information, the file security system is able to subsequently modify access criteria for secured files (documents) without having to physically make modifications to the secured files.
