An Image Steganography Algorithm Using Huffman and Interpixel Difference Encoding

ABSTRACT Steganography is associate degree art of activity secret info on a canopy medium through subliminal methodology. The 3 pillars on that a steganography algorithmic program ought to be erected are: Embedding capability, physical property and hardiness. its lucky that each one these goals square measure mutualist on each other. The state of art is finding associate degree optimum resolution that sustain all the steganography goals. its believed that theres no productivity if the scale of canopy medium gets extended to fulfill in housing the key knowledge thereon. This happens attributable to lack in refinement of embedding algorithmic program and failing in analyzing {the knowledge|the info|the information} structure of secret data. during this paper, an endeavor has created to enhance embedding capability and produce terribly less distortion to the quilt medium by analyzing the information structure of the payload. A residual secret writing is carried on the pay load before its submitted to Huffman cryptography that may be a lossless compression technique. As a result, the illustration of payload had shrink. Further, the variable bit cryptography (Huffman) do a lossless compression and at last the payload get housed on the quilt medium. This finished with high embedding capability and fewer physical property. Peak signal to noise quantitative relation confirms that the residual secret writing had given jury-rigged results than few existing embedding algorithmic program.
