In this paper we focus on improving the optimized content-aware authentication scheme over lossy network [1] and incorporating this scheme into secure scalable streaming (SSS) and secure transcoding with JPEG-2000 Images [2]. SSS encodes, encrypts and packetizes image into secure scalable packets in a manner that allows downstream transcoders to perform transcoding operations by simply truncating or discarding packets without decrypting the data. However SSS does not consider the issues of packet loss and stream authentication while the stream is transmitted over today's public and lossy networks. This paper proposes an improved optimized content-aware authentication scheme and implements a system to integrate it with SSS seamlessly. Experimental results demonstrate that the proposed scheme achieved our design goal in that the R-D curve of the authenticated image is very close to its original one where no authentication is applied.
