Hamming Coded Watermarking for Image Authentication and Evaluation by Image Transmission using Digital Modulation Schemes
Abstract: Proposed watermarking scheme for image authentication and tampered detection. Here, image encoded with a message is generated, after embedding watermark symbol within a colour cover image. The message information is converted to hexadecimal values from its ASCII representation. To encode this and embed the watermark, (7, 4) Hamming code is used. These bits will be divided into 7-bit blocks which will spread across the width of the image. The proposed …
