A steganography approach for sequential data encoding and decoding in video images

The recent growth in computational supremacy and communication technology has propelled today´s security technique called steganography to foremost. Essentially, a steganography system uses encoding and decoding algorithms to hide the secret data in cover-medium to produce stego-medium. A data hiding approach for embedding secret data in video images is presented. This paper is aimed to transmit maximum hidden data without losing the video quality and size. In order to achieve this goal, in this system we are using the encryption key for sequential data encoding and decoding. The system is implemented in MATLAB environment. The performance of the steganography approach has been evaluated using video images in bit mapped (bmp) format in Red, Green, and Blue (RGB) components. The experimental results prove that the sequential encoding based steganography system is simple and produces imperceptible distortions in resulting bmp images.
