TECHNOLOGY SURVEY ON DIFFERENT STEGANOGRAPHY TECHNIQUES

The paper describes short survey on different steganography techniques for an image in spatial and transform domains and steganalysis techniques for hide the secret message. The strong and weak points of these techniques are mentioned briefly so that researchers who work in steganography and steganalysis gain prior knowledge in designing these techniques and their variants. One can develop a better steganography technique by analyzing the contemporary steganalysis techniques
