Data Hiding in Image Mosaics by Visible Boundary Regions and Its Copyright Protection Application against Print-And-Scan Attacks

Abstract

A data hiding method in image mosaics for copyright protection against print-and-scan attacks is proposed. By adding visible boundary regions to the four sides of tile images to represent bit pairs, a binary data stream can be embedded into an input image mosaic. By detecting the visible boundary regions of the resulting stego-image mosaic, the embedded data can be extracted for copyright proof, even after the stego-image mosaic is attacked by print-and-scan operations. Experimental results showing the effectiveness of the proposed method are also included.
