Abstract

We proposed a hybrid digital watermarking scheme in wavelet domain with double encryption of silicon photonic microcavity chaotic encryption and Arnold transform. In particular, the SPM-Chaos is four-dimensional dynamic chaos generated by silicon-based photonic crystal optomechanical microcavity, which brings higher randomness and larger keyspace. In this article, the hybrid encryption of SPM-Chaos and Arnold transform can greatly enhance security. Meanwhile, using DWT due to wavelet’s time-frequency localization and multi-resolution characteristics which are applicable for image processing. The experiment results show that proposed scheme has good visual invisibility, and robustness against various attacks such as noise, filter, rotation and compression.
