A robust and secure InIm(Integral imaging)-based 3D watermarking scheme using cellular automata transform (CAT) is proposed. In the InIm-based 3D watermarking scheme, the elemental image array (EIA) watermark for the target watermark, which has to be detected, is synthesized from the computational pickup process of InIm and embedded in a cover image. The EIA watermark can provide a robust reconstruction of the target watermark. However, the 3D property of the EIA watermark causes a weakening of the security. To overcome this problem, the proposed method uses the CAT domain to embed and extract the EIA watermark in the cover image. The use of CAT significantly improves the security for our watermarking algorithm using a single secure key only. Experiments are presented to show that the proposed scheme shows robust and secure performances against various attacks.
