Abstract: Joint video compression and encryption techniques gain good attention in recent years due to its reduced computational complexity, memory utilization and execution time. In this study, a modified encoding algorithm called Enhanced Randomized Arithmetic Coding (ERAC) is proposed for joint compression and encryption. The Randomized Arithmetic Coding algorithm (RAC) is modified to integrate encryption with compression. In ERAC, the video data is encrypted using a secret key during compression. It is simple to implement and has less computational overhead. The proposed ERAC technique has two modules, namely, Randomized Arithmetic Coding (RAC) module and the XOR module. The experimental results achieved and analysis of the proposed solution shows that the enhancement done over RAC provides high security without compromising the compression ratio and speed.
