The multimedia technology has a rapid development in various fields like medical, commercial, and defence. Therefore, security and privacy has become an important. In this paper the zigzag method based on block scrambling for the process of encryption and the compound mapping function is used for data hiding in encrypted video. The concept of applying the algorithm is explained in detail and its performance is also analysed. Its various parameters like performance in terms of speed and strength of encryption are compared with the original zigzag algorithm. The result enhances that the block based scrambling approach performs better and data recovery is lossless and highly privacy.
