Efficient data hiding scheme using lossless data compression and image steganography
Rahul Jain, Naresh Kumar · 2012
Steganography is an art of hidden communication in which secret message is embedded into a cover image. It has many applications like Online transactions, military communication etc. In this paper, we have proposed a data hiding scheme using image steganography and compression. This scheme can be applied to gray scale as well as color images. This scheme improves the data hiding capacity of the image as compared to other existing image steganography methods while retaining the quality of the image after embedding the secret message into it. The improved embedding capacity of the image is possible due to preprocessing the secret message in which a lossless data compression technique is applied.
