An Enhanced Approach for Image Steganography in video

Steganography is a method used to transmit covering information by changing an audio signal in an invisible manner and is an art of hiding information in ways that avoid declaring hidden messages. The secure data transmission over internet is achieved using Steganography. Video files are generally a list of images. The presented techniques on images and audio can be enforced to video files too. The great advantages of video are the large amount of data that can be hidden inside and video is a moving stream of images. The network provides a method of communication to distribute information to the masses. The Security of information has become a major issue with the growth of data communication over computer network. Steganography and cryptography are two different data hiding techniques. Cryptography, on the other hand obscures the content of the message. In this research work we proposed a high capacity data embedding approach by the combining two approaches LSB and DWT.
