Hiding Data in Video Stenography by Using Different Algorithm: A Review
Simaranjit Kaur · 2015
Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner and is an art of hiding information in ways that avert the revealing of hiding messages. Video files are generally a collection of images. so most of the presented techniques on images and audio can be applied to video files too. The great advantages of video are the large amount of data that can be hidden inside and the fact that it is a moving stream of image. The network provides a method of communication to distribute information to the masses. With the growth of data communication over computer network, the security of information has become a major issue. Steganography and cryptography are two different data hiding techniques. Cryptography, on the other hand obscures the content of the message. We propose a high capacity data embedding approach by the combination of Steganography and cryptography.
