Encryption of Text File in a Video Using Adaptive Compression of Video

Steganography, is the art of providing security to text file by embedding into a carrier which can be a text or an multimedia file. This paper proposes a method for the real-time embedding of information in a compressed video. Unlike images Video files are generally a collection of images which can be more eligible than other multimedia files, because of its size and memory requirements. The great advantages of video files are the large amount of data that can be hidden inside and the fact that it is a moving stream of image. This paper provides a new technique that is motion vector is used to embed the data in the moving objects. We focus on the Least Significant Bit (LSB) technique is an important insertion technique for embedding data into video file and comparing the qualitative and quantitative performance of algorithms (compression).
