Image/message Steganography using LSB insertion Algorithms for DRM system

Digital Rights Management (DRM) system is the effective scheme for digital transactions. The main disadvantage of DRM is that once the content is decrypted, it can be easily copied using widely available utilities. It can be removed by using protection system like steganography. Steganography is the art of communicating in a way which hides a secret message into the main information or cover. The most common approaches to information hiding in images are in time domain, Least Significant Bit (LSB) insertion, in frequency domain using Fast Fourier Transform, in spatial domain using Wavelets. In this paper, the hiding of information of images and messages are implemented in time domain using LSB insertion method. The encoding and decoding algorithms are developed and successfully implemented in MATLAB graphical user interface. LSB insertion method in image Steganography works effectively for 24-bit–map (BMP) and PNG image formats. The proposed algorithms are simple to implement and gives better results.
