Abstract:

This paper proposes a new steganography method using texture construction. The data-hider first constructs a database of elements containing many different patterns and features used to represent secret bits. The data-hider selects patterns and features from the database according to the secret message. The selected elements are painted onto specified positions on a white paper, and some background elements added to the painted paper. With pre-defined transforming functions, the data-hider transforms the painted image to construct a stego-image. On the receiver side, secret messages can be extracted from the stego-image using the inverse operations. Experimental results show that the constructed stego-image has good visual effects, and the secret messages can be properly hidden into the image. Meanwhile, any amount of message can be hidden by choosing different parameters.

Key words: information hiding, texture synthesis, steganography
