“…Data embedded using these methods may results into distortions of sharp edges which are more sensitive to human visual system. Some image complexity measures like correlation coefficient [15], complexity gene [16] also used to find the appropriate location in the cover image to hide the secret message. Secret information is always embedded into the regions with high complexity so that the embedded image has better quality.…”

Data hiding is the process of concealing the existence of one type of information into another. In reversible data hiding techniques, original host image can be successfully restored from the marked image after the exact extraction of the secret information. In recent years, various modifications of this technique have been proposed. In this paper, the reversible data hiding technique based on prediction error expansion is modified by hiding the secret information using selective embedment as per complexity gene. Information hiding starts from the most complex block to lowest one which is evaluated on the basis of complexity gene. It also uses the Arnold cat map to encrypt the secret information, thus provide one more level of security to the scheme. Simulation results shows that the modified method has better PSNR, more information hiding capacity & enhanced levels of security then the existing technique.

“…After dividing the image into non-overlapping blocks, the complexities of these blocks are calculated with the help of C gene (Complexity gene) [16]. The value of Cgene is changed by changing the values of the α 1 , α 2 and β and these parameters are utilized as a key.…”
