An Image Authentication Algorithm Using Combined Approach of Watermarking and Vector Quantization

This paper presents a two-stage watermarking technique for image authentication adapting the advantages of vector quantization (VQ). In the proposed algorithm, robust watermark and semifragile watermark are embedded independently in two successive stages. Robust watermark and VQ enhance the security...
