As most documents have been digitized and transmitted over the Internet, it becomes very crucial to protect the integrity of them. Integrity is the process of ensuring that a document is changed by unauthorized users. In this paper, inspired by the Yang and Kot's method, we proposed a novel scheme to verify the integrity of binary documents by using its digital patterns. We compute the black patterns and white patterns of a document and embed watermark information in it. The experimental result shows that by using our proposed method one can verify the integrity of a digital document, any little change made to it can be detected easily.
