Internet source and digital media tools have become daily requirements of the society.A major problem in digital communication is secured data transmission.Steganography is a technique of hiding confidential data in the media files such as audio, images and videos, in a cover model to provide secured communication.Video steganography process is an authenticated communication to hide secret information from unauthorized user(s) through a video file as cover medium.In this article, an architecture is developed to hide input secrete image into a cover video.The secret image is encrypted by RSA algorithm, further continued with data shuffling by using Fisher Yates algorithm.Then Discrete Cosine Transform is applied to generate 8*8 blocks.On the other side, video is discretized into frames which are applied with DCT to form 8*8 blocks which are embedded with earlier generated blocks that results in a stego-video.Performance analysis is also carried out to enhance embedding capacity, imperceptibility, robustness and security.
