Electronic Document Secure Management System Based on Content Analysis for Enterprise

Abstract

Electronic document management system is a critical component of enterprise. To enhance the security of the management system was not only by Public Key Infrastructure (PKI), such as public key, private key, and symmetric key based encryption and decryption, digital signature, and the key and certificate automatic management, but also by intelligent text analysis, which extracted word weight info automatically to generate security level of the doc using centroid-based classification and integration with experts’ experience, and combined file’s attributes to classify the electronic docs into the managed directory and database, and to locate the electronic docs, while checking the security level of the doc to control the access. Meantime, we used the plugin for the doc transparent encryption and decryption, and the digest signature with system-side private key for all docs. Furthermore, we utilized the user interface (UI) for users’ convenience, which employed a partial submission strategy, improving the efficiency of the doc management.
