Abstract

In this paper, we present a new approach for digital audio watermarking scheme in three-dimensional (3-D) space. The architecture of 3-D digital audio watermark insertion is on the basis of virtual optics imaging system (VOIS), which relies on the propagation of virtual light wave through discrete Fresnel diffraction (DFD). The embedding strategy of a watermark with a methodology of the VOIS is analyzed in detail under the framework of Fourier optics. In order to test the robustness against signal processing, we carried out several detection experiments. Common audio signal manipulations like adding noise, filtering and data compression are used. Simulation results have shown a good agreement to theoretical predictions.
