Abstract
This paper proposes a method for information hiding based on doubled-random phase encoding technology. In this method, data is split into real and imaginary compartments. The real part of the encoded data is embedded into a large enough host image, together with the imaginary part through grey level superposition. The composed image is not subject to severe degradation compared to the original host image. During the decryption process, the composed image is decrypted directly without the use of the original host image. Factors affecting the quality of the composed image as well as the reconstructed image are discussed. It is shown how optimum results are achieved by adjusting the superposition weight of the definitive host and hiding images.Keywords
