Abstract
Steganography is one the main method of data hiding technique. So, it has wide varieties of applications in hiding secret information such as in the field of medical, military, law forensics and co-operate field etc. Here image steganography with Adaptive Pixel Pair Matching (APPM) and image sharing is used. The basic concept behind APPM is, consider the pixel pair value as a reference coordinate, and then find the neighborhood set of this pixel pair according to a given message digit. The secret data digit is embed by replacing of pixel pair and the searched coordinate. Security is a major issue in these systems because data embedding causes modification to the cover image pixels. By analysing these distortions, an attacker can easily detect the presence data hiding. In order to avoid these situations, this paper describes an efficient data hiding method based on APPM and image sharing. Here image sharing is done by using shamir’s secret share algorithm. The experimental results show that the proposed method is much better than the existing methods.
