This paper presents a digital watermarking algorithm based on the DWT coefficients. This algorithm does not change any information of the original image
but combines the information of low frequency DWT coefficients and the watermark image. The combination is the key
which is used to extract the watermark. When we need to extract the watermark
we can obtain it by divide the key. Because the algorithm does not change any information of the original image
it will not affect the quality of the original image. Experimental results show that the proposed algorithm is robust and secure against a wide range of image processing operations. 2011 IEEE.
