Data Concealment in Video Using Allowable Zone Hiding and Choosy Embedding via Des Encryption

Data hiding in video is an important research issue as the traditional methods are error prone and leads to distortion. However, most of the video data hiding methods utilize uncompressed video data. Recent video data hiding techniques are focused on the characteristics generated by video compressing standards. A new blind data hiding method is proposed based on a novel concept of forbidden zone, where no alteration is allowed in a host signal during message embedding step. It makes use of erasure correction capability of repeat accumulate codes and superiority of forbidden zone data hiding. Choosy embedding is utilized in the proposed method to determine host signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order to withstand frame drop and insert attacks. The framework can be successfully utilized in video data hiding applications.
