摘要：Multimedia security is a challenging task in worldwide distributed environments and due to the violation of copyright digital media industry is suffering huge financial loss. Widely used compression standard for video file is MPEG, and on the basis of motion prediction MPEG data consists of three different types of frame i.e. I-frame, P-frame and B-frame. Digital watermarking is a technique used to protect the multimedia contents from illegal use. In-visible digital watermarking is an effective way to protect copyrights of multimedia by embedding a special and invisible pattern in data which contains the information about the identity of the owner. Most of the watermarking techniques a re marking only I-frame to protect the copyright of multimedia files. These technique are providing reasonable security of data but still not fully able to protect the contents from illegal distribution. This paper involves to study the different frame of MPEG compression standard and to explore the different security concerns in multimedia data. Also we have identified the common security requirements, mechanism, security measures, important parameter and attacks for video data. Moreover to investigate and evaluate the existing watermarking techniques and to address its applications.
