An optimal modified matrix encoding technique for secret writing in MPEG video using ECC

• We secure the hidden data against the effect of steganalysis by reducing the rate of distortion in the stego-image.
• The security and robustness is improved using multiple elliptic curves in cryptographic algorithm ECC.
• Using multiple elliptic curves for generating the cipher improves the robustness of encrypted secret data of user.
• Encrypted cipher is then embedded into user's video using the Optimized Modified Matrix Encoding (OMME) technique.

In recent years, Information Security in the field of digital communication is a relevant part because the advancement hiked the fear of receiving the data snooped at the time of sending it from the sender to the receiver. So, a secure technique is designed by amalgamate both Cryptography and Steganography. Initially, user's confidential details are encrypted using the more secure Multi curve Elliptic Curve Cryptography (ECC) technique. Next, the encrypted cipher is embedded into the H.264 Video using a novel proposed Optimized Modified Matrix Encoding (OMME) steganography technique to embed the secret data. While embedding the encrypted confidential details into the video, pixels from the frames can be selected using an optimization algorithm called Artificial Bee Colony (ABC) in order to reduce distortion of stego video. Finally, the user's secret data embedded in the H.264 Video is extracted and it is de-ciphered. This proposed technique increases the level of security and robustness against attacks in terms of carrier capacity and embedding efficiency when compared to existing methodologies. The proposed work is implemented in the working platform of Matlab and provide data hiding in MPEG video files.
