A chain-frame pixels are transposed, substituted, and embedded at the LSBs of the correspondent host frame. The proposed method can detect and prevent from illegal falsification attacks of multimedia content, such as modification content, insertion or deletion content. The protection and verification algorithm can be announced by using private keys architecture to protect the security of embedded data. The experimental results demonstrated the efficiency of the method.
