In this paper,a digital text watermarking algorithm based on Chinese characters structure is proposed.Accounting to the content of text,it isn't influenced by the text formatting.Based on the distinguishing of the Chinese characters structures,the eigenvalue of every sentence is computed and compared those binary eigenvalue sequences with the watermark binary sequences,and then it is embed watermarking through changing some eigenvalues.Through theoretical analysis and experiments,the algorithm is easy to implement and has an effective invisibility.Furthermore,it has a better watermarking robustness and security.
