摘      要：正With the development of computer technology,digital images’ integrity and authenticity are queried more and more *** a protection and authentication technology,digital watermarking technology has been used in image *** this paper,a multiple digital watermarking algorithm is proposed based on integer wavelet transform to protect digital images and estimate its integrity and *** 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 *** 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.
