Concealed Message Transfer Using Lifting Scheme Based On Video Steganography

P. Sherubha, P. Abinaya

Nowadays security threats become increased, confidential information, such as medical records, chemical formulas and banking data are at risk. This paper provides a technique for communicating the data secretly using cryptography and steganography. Cryptography is the encrypting process in which the plain text converted into another form (i.e. cipher). Steganography is a technique of hiding the data in any media such as, image, audio and video. In this paper steganography performed on video files and hide the message in an encrypted format. The common method used for concealing the data is LSB. Instead of that we will use an encoding technique which will first transform the video using Lazy Lifting Wavelet transform and then apply LSB in the sub bands of the video. Bit Exchanging method is used for encryption. The encrypted data hidden on video using LSB. Steganography method provides robustness, capacity, undetectability and invisibility.
