摘要：With the rapid advance in digital network, digital libraries, and particularly WWW (World Wide Web)services, we can retrieve many kinds of images on personal and mobile computer anytime and anywhere. At the sametime, secure image archiving is becoming a major research area because the serious concern is raised about copyrightprotection and authority identification in digital media. A more sophisticated technique is required for futuremultimedia copyright protection. Steganography is the idea of hiding private or sensitive data or information withinsomething that appears to be nothing out of the normal. Steganography and cryptology are similar in the way that theyboth are used to protect important information. Nowadays the term “Information Hiding” relates to both watermarkingand steganography. This paper intends to give an overview of image steganography and various techniques likeDiscrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), Least Significant Bit (LSB), Hash LSB andSpread Spectrum.
