Watermarking scheme using local binary pattern for image authentication and tamper detection through dual image

Abstract

Watermarking scheme is an efficient solution to protect the multimedia document from unauthorized modification. Several watermarking scheme have been developed but authentication and tamper detection is still an important research issue. In this paper, a dual image‐based watermarking scheme has been developed using local binary pattern (LBP) to protect the multimedia document from illegal modification. The suggested method includes the following procedure: During watermark encoding the host image is partitioned into (3 × 3) nonoverlapping blocks. Then generate system vector (s) using LBP and perform XOR with secret watermark bits. Two bits authentication code is generated from S vector and embed within dual image depending in a shared secret key (δ). At the receiver end, the embedded watermark, authentication code, and original cover image can be successfully recovered from dual watermarked image. After that authentication process has been carried out by comparing extracted authentication code and the regenerated authentication code. The experimental results are compared with the state‐of‐the‐art methods to show the effectiveness of our proposed scheme. It is observed that the proposed scheme is secure and robust against different standard attacks meanwhile it can detect message integrity within the watermarked object.
