An efficient key management solution for privacy masking, restoring and user authentication for video surveillance servers
This paper proposes a key distribution scheme for distributed video surveillance servers. The scheme introduces security protocols to authenticate multiple privileged users. The scheme also includes privacy masking and restoration strategies used in case of crimes. Hierarchical restoration of the privacy masks with different privileges is possible using the proposed scheme. Security evaluation on the proposed protocols is included in a new section.
