Abstract


Steganography is the principles and techniques of embedding data within other data. Cryptography is the principles and techniques of changing the data one form to another form. Image Steganography is the process of hiding data within an image. Steganography along with encryption techniques provides an additional security to the data. Several techniques exist for image steganography, in this work, a new lossless image steganography technique along with cryptographic method is presented. Lossless compression is a class of algorithms that allows the original data to be perfectly reconstructed from the compressed data. Present work concentrates the lower nibble of pixels in the cover image for embedding the information; further encryption techniques will be applied. It is not possible for the hacker to retrieve the secured data from the cover image.
