High Imperceptible Data Hiding using Remainder Method

In this paper we will propose a high quality image steganography technique which can hide secret data within an image in such a way so that it is imperceptible to human eye. This method solves the overlapping problem of remainder and use modulo operator efficiently for hiding purpose. First, we calculate the base eight equivalent of target string. That increases the hiding capacity as well as robustness of the stego image. Then the secret data can be hidden by remainder method. In our proposed work we alter the remainder of pixels in such a way so as to greatly reduce the image distortion caused by the hiding of the secret data. Experimental result checks the quality of stego image as well as compared with standard LSB technique and 3 LSB multi-bit image steganography technique. Experimental results have also demonstrated that the proposed scheme is secure against StirMark Benchmark 4. 0.
