Research on System of Chinese Document Copy Detection

Text copying is easy to do but not easy to be detected. Copy detection is a delicate ground. It determines whether a document is copied from others or not. It helps to verify and to detect paper redistribution, thesis plagiarism or copyright violation. A novel method of Chinese text copy detection design and implementation is discussed in this paper, based on theory of mathematical expression of Chinese characters. It can implement the functions include characteristic reconstruction, registration and detection. Experimental results show that the system has the advantages on detecting accuracy and high speed.
