The Multiple Huffman Table (MHT) based encryption technique for multimedia encryption gained much popularity, due to its simplicity, less complexity and good compression performance. At the same time, it is proved that the MHT based encryption system is vulnerable to several types of attacks. In this paper, the security issues of the MHT based encryption system are analyzed. On the basis of analysis, the paper proposes a modified version of MHT based encryption system, with minimal impact on its simplicity and compression performance.
