A Survey of Information Hiding Schemes for Digital Images

Abstract

[[abstract]]In this survey, we first describe the purposes for image hiding. They are Steganography, Image Watermarking and Image Authentication. Classified by hiding methods, image hiding can be divided into pixel-based image hiding, frequency-based image hiding and VQ-based image hiding. In the aspect of pixel-based image hiding, we describe three representative methods, the substitution table technique, the modulus function technique, and the LSB matching revisited technique. As for frequency-based and VQ-based image hiding, we introduce methods to do Steganography, Image Watermarking and Image Authentication by applying image compression methods, JPEG and Vector Quantization
