A Private Photos Keeper System Based on Spatial Domain Techniques

As a result, many people have met a serious problem about how to make their private digital photos in safe keeping. The leaked private photos always cause great trouble for the owner. In this paper, we will propose a Private Photos Keeper (PPK) System for keeping digital private photos safely. The methodology of PPK system keeps photos in a kind of invisible state via steganography techniques. Many steganography techniques have been proposed. Almost all of the proposed techniques emphasize to satisfy three requirements: Imperceptibility, Capacity and Robustness. Considering the photos´ characteristic, in our PPK system, we will focus on the Capacity parameter and attempt to maximize its value through analysis the constraint of the interactional three properties. The PPK system is based on spatial domain techniques.
