Abstract

In today’s scenario of internet world, hiding data with security is the highly challenging and desirable task. There are large numbers of techniques available which are capable of hiding data in cover media. The purpose of this research work is to develop a novel, secure and high capacity data hiding technique in 24 bit true color image. This novel approach uses pixels of 24 bit true color image to hide secret message. The proposed approach is adaptive and according to size of data it decides best possible technique to hide data in true color image. The developed technique applies multiple security mechanisms using randomization and data hiding methods. The major focus in this proposed work is to hide more data with higher security in cover media. In this approach the pixels that are going to contain the data are selected randomly based on the random key. At the receiving end it is difficult to retrieve secret data without secret key. The main advantages of proposed approach are: First it is adaptive, i.e. depending upon the data size, it automatically decides the best technique for hiding. Second it is secure due to randomization in the pixel and channel selection. Third it provides high capacity for hiding data in cover image. Keywords- LSB, MSE, PSNR, Steganography.
