A secure media sharing using encoded integrated dynamic steganography approach

Information sharing over the public domain is one of critical challenge. In this paper, a two stage model is discussed to perform adaptive information encoding and dynamic steganography approach. At first level of proposed model, the adaptive encoding approach is dictionary based approach that performs the cyclic shift to encode the textual or image information. At second level of proposed model, a dynamic frequency analysis approach is based on to identify the adaptive key areas over the image to hide the information. Once the adaptive pixels are identified, two-bit LSB is applied to perform the steganography. The paper is applied on sample imageset and the results show the effective information hiding with lesser MSE and higher PSNR values.
