This paper presents a new blind logo watermarking algorithm based on wavelet packets. For increasing robustness and security together, the logo watermark is scrambled n times and each time with a different private key to generate n scrambled copies of the logo watermark. To embed the logo watermarks, the host image is decomposed by wavelet packets transform and then the scrambled logos are embedded in selected sub-bands of wavelet transform by quantization technique. Knowing the quantization… CONTINUE READING
