A Novel Embedding Scheme Based on Walsh Hadamard Transform
The purpose of steganography is to send secret message by embedding data into some innocuous cover objects such as digital images. The data hiding method used until now is the syndrome coding method. In this paper, the authors present an improved data hiding scheme defined by Boolean functions. Using some properties of Boolean functions they construct a new steganographic scheme in which they can hide more information compared to the scheme based on syndrome coding.
