An efficient key management solution for privacy masking, restoring and user authentication for video surveillance servers

초록

In this paper, we surveyed technical elements of video surveillance systems and proposed several countermeasures to effectively manage a number of keys for image encryption, privacy protection and user authentication. In addition, we proposed several solutions for potential problems that could arise when the system adopts a privacy masking policy for each user. The proposed solutions selectively implement a Kerberos approach, a round keys approach and a double hash chain approach. For secure video surveillance systems, protecting privacy and providing accessibility through strong user authentication and prioritized authorization is expected. (C) 2015 Elsevier B.V.
