A novel data hiding technique using residue number system

Data hiding technique is a very attractive field. The field of data hiding in imagery is relatively very young and is growing at an exponential rate. This field is highly multidisciplinary field that combines image and signal processing with cryptography, communication and visual perception theory. In this paper a new data hiding technique based on residue number system is introduced in digital imagery system. This technique is used to encode two digital image signals or one text with one image signal, which are quantized with 8 bits using residue number system (RNS) technique and multiplexed together. Also the de-multiplexing technique to separate the original image signals is simply performed successfully. Simulation results are given.
