Improving security and efficiency of enterprise digital rights management

Recently, private enterprises, governmental and military institutions have been relied mainly on digitizing their work. Digital files containing sensitive information should be protected against external and internal malicious attacks. Enterprise digital rights management (E-DRM) schemes provides several approaches to protect and securely distribute digital contents while empowering the enterprise´s administration to monitor and control access to these contents. In this paper we propose a new secure and efficient E-DRM system based on the Information Dispersal Algorithm (IDA). We achieved an improvement in the overall storage requirements, and the computations complexity at each server in the system, as well as preserving the security of information and system robustness.
