Abstract

This paper introduces a new watermarking solution for single-sensor digital cameras. The proposed method embeds visible watermarks in the color filter array (CFA) domain of captured images and uses the demosaicking process to transfer the watermark from the gray-scale CFA image to the restored, demosaicked, color image. Thus, the approach allows for cost-effective image protection and the enforcement of digital rights and intellectual property rights in single-sensor images
