A Survey Paper on Various Encryption & Data Hiding Methods for Video Streams

Shrutika S. Giradkar, Antara Bhattacharya

Abstract: With the rapid development of various multimedia technologies, more and more multimedia data are generated and transmitted in the medical, commercial, and military fields, which may include some sensitive information which should not be accessed by or can only be partially exposed to the general users. Therefore, security and privacy has become an important issue. Many researchers have proposed various methodologies to maintain security and privacy before digital video transmission. Hence the digital videos are encrypted by using various encryption methods. For the purpose of content notation and/or tampering detection, it is necessary to perform data hiding in these encrypted videos. For data hiding there is a need of better data hiding algorithm that will work on encrypted media. This paper focuses on the interoperability of video encryption & data hiding method with existing processes for the video streams. In this survey we present an overview and classification of the various encryption and data hiding methods for video streams.

Keywords: Data hiding, Encrypted domain, H264/AVC video streams
