摘要: Data hiding is a technique that allows secret data to be delivered securely by embedding the into cover digital media. In this paper, we propose new algorithm for H.264/advanced video coding (AVC) of sequences with high capacity. proposed scheme, embed quantized discrete cosine transform (QDCT) coefficients frames without any intraframe distortion drift, some embeddable coefficient pairs are selected in each block, and they divided two different groups, i.e., group averting group. The used carry data, prevent drift adjacent blocks. experimental results show scheme can avoid guarantee low sequences. addition, provides enhanced capacity compared previous schemes. Moreover, embedded extracted completely requirement original data.
