Image Steganography Using Bit Differencing Technique

The swift progression of evidence correspondence in contemporary time demands protected communication of data. Steganography obscures personal material in numerous record organisations, for example, photograph, content, sound, and audio–visual, impalpability, payload and vigour are the key complications on the way to steganography. This proposed work would give a nascent procedure that could be used for storing imperative data inside some cover metaphors by means of most significant bits (MSB) of the cover metaphors that have been presented. Firstly, the bits are numbered in increasing order, and bit number 6 is concerned over storing the confidential data which is based on the difference of bits 6 and 7. The result is generated on the basis of the difference whether the resultant bit is same as that of secret bit or not. If the resultant bit is distinct as compared to confidential pixel, the bit number 6 is modified and updated in the original bit. The outcome communicates the suggested model that must give good percentile of improvements in signal-to-noise ratio. Here, picture is fragmented into red, green and blue components where red components used for signalling on the way to store information in green or blue components of the portrait. The proposed method built on most significant bits (MSB) is used for safeguarding the organisation from unauthorised admittance, and the interlopers would not be intelligent to admittance the intimate data.
