Digital Watermarking in RGB Domain on Weighted ECC

Abstract

Digital watermarking is a technique for embedding imperceptible mark into digital content, with further extraction of this mark. This paper proposes a watermarking method to embed watermark in the spatial domain using error-correcting codes. Image is divided into blocks. Two perfect error-correcting codes are used to embed watermark. Codeword of corresponding perfect code is written into one block to embed one watermark bit.
