| Abstract: | ABSTRACT In the proposed technique we have merged two layers of security, namely, the watermarking layer and the secure channel management layer used in the framework of a real time multimedia security system. The joint layer embeds watermark to the host signal and deploys encryption simultaneously to protect multimedia data, thereby reducing the processing delay. The scheme supports G.729 codec bit-stream. Encryption is done using Data Encryption Standard (DES) protocol. The computation time and watermark-embedding rate is evaluated for the proposed algorithm. |
