Application of data hiding in Audio-Video images Using Anti Forensic Technique for authentication and Data Security

Abstract

Steganography is the method of hiding any secret information like password, text and image, audio behind
original cover file. Original message is converted into cipher text by using secret key and then hidden into the LSB of
original image. The proposed system provides audio-video cryptostegnography which is the combination of image
steganography and audio steganography using Forensics Technique as a tool to authentication. The main aim is to hide
secret information behind image and audio of video file. As video is the application of many still frames of images and
audio, we can select any frame of video and audio for hiding our secret data. Suitable algorithm such as AES is used for
image steganography suitable parameter of security and authentication, hence data security can be increased. And for
data embedding we use 4LSB algorithm.
