In the recent years, with the development of network and multimedia technology, multimedia data, especially image, audio and video data are used more and more widely in human society. In this regard, to protect multimedia contents, cryptology, which appears to be an effective way for information security, has been employed in many practical applications. This Paper, make a survey on various techniques for securities of Multimedia content using soft computing approach
