摘要: | This paper presents a reversible fragile watermarking scheme for the authentication of demosaicked images. Each authentication code is embedded into the two rebuilt components of each color pixel by using a designed authentication table (ACT). The utilization of ACT secures the watermarking procedure and the watermarked image can be recovered back to the original demosaicked image by the proposed scheme. The proposed scheme is compared with some existing image authentication schemes, and the experimental results demonstrate that our scheme can preserve better image quality and provides superior tamper detection performance. |
