简介
Intentional tampering in digital image content is one of the common malpractices in the current digital arena. So in this paper, the authors have proposed a novel fragile watermarking scheme for the localization of tampered image content effectively. Proposed fragile watermarking scheme detects forged image content robustly in block level of two consecutive pixels. In this work, the watermark embedding procedure is comprised of two phases- i.e., authentication code generation from some selected salient bits of each pixel of the original image content, and encryption of the authentication code before realizing it for embedding into the insignificant bits of each pixel in the original cover image. The authentication code is computed from each block using Hamming Code. Subsequently, the encrypted code is concealed into the pixels of that particular block using the suggested payload embedding strategy i.e., pixel …
