Towards Novel Video Steganography Approach for Information Security

Abstract

Communication security has taken vital role with the advancement in digital communication. The universal use of internet for communication has increased the attacks to users. The security of information is the present issue related to privacy and safety during storage and communication. This paper deals with the proposition of a multilayered secure channel to transfer sensitive data/video over an unreliable network. The secret video is first encrypted using the NOLSB algorithm. The cipher video produced is hidden in a video file with more size. This video file is in turn encrypted following the (m,k) firm technique to maximize resource utilization and to optimize the bandwidth. Then video shares are sent over many channels in the network in order to assure security. This method guarantee that, even if some shares got lost over network, video files could be recovered at the end receiver without need to resend the video file by the sender.
