Multiple Digital Watermarking Algorithm to Protect Digital Images Based on Integer Wavelet Matriz Norm Quantization
With the development of computer technology, digital images integrity and authenticity are queried more and more widely. As a protection and authentication technology, digital watermarking technology has been used in image field. In this paper, a multiple digital watermarking algorithm is proposed based on integer wavelet transform to protect digital images and estimate its integrity and authenticity. Using matrix norm quantization, it embeds watermarks into low-frequency, medium-frequency and high-frequency detail sub-bands of images integer wavelet domain and it is a blind-testing watermarking algorithm. Attacking experiments show that the algorithm not only has both robustness and sensitivity, but also exactly locates distorted area, so it is an effective multiple digital watermarking algorithm.
