%X This paper presented a blind detection watermarking algorithm for document image to hide information against print scan process. Considering the characteristic of the document image, firstly, cut the original document image into several blocks, each of which included only one word. Then decomposed each image by discrete wavelet transform(DWT) for three degree and embedded watermarking by modulate the count of the positive and the negative of each detail subband. Experiments show this algorithm suit for document image and it can survive the print scan process.
