Hiding Data in Image using Extended Pixel Mapping Method

Abstract

— Internet technologies are currently charring an important role in our day to day life. It has the benefit as well as disadvantages also.This in term generates the needs of data activity technology for maintaining the secrecy of the key information. The steganograpic concept of data hiding is used in this method. The method used spatial domain technique. This algorithm used image as a carrier medium for hiding the data. In this pixel component are used for hiding the data. For achieving this pixel index value and their position are calculated. According to this key will be generated and by using key data is hided.Experimental result shows that the perceptual quality of hided image is high in this technique. The key idea of this project is to hide the data in carrier image and retrieve data from carrier image without affecting without affecting the perceptual transparency of the data hided image. This system provides compression of data so that payload capacity of the system will be increases.
