摘要
This paper reduces the detectable distortion in a joint photographic experts group (JPEG) file during data hiding process, by introducing new region selection rule. The new region selection rule considers three factors, i.e., the horizontal difference (HD), vertical difference (VD) and region size (RS). The JPEG image will be split into number of blocks and each pixel in it will be examined to calculate the variations. Depends upon the variation, the amount of secret information will be hide in an image. This proposed method of information hiding will help to solve the security issues in computer networks. The experimental result scrys that, the proposed system hides approximately 45% of secret information in addition, comparing existing methods without increasing detectable distortion.
