Abstract: Aiming at the reliable transmission security problems of electric power system texts, multiple text watermarking algorithm is first applied into protecting it. Take protecting the transmission of electricity price in the in electric power system text and authenticating the content from the sender for example, and robustness watermarking algorithm is employed to transmit the electricity price with covert communication which makes it possible to resist different kinds of attacks. The semi-fragile watermark is utilized to confirm the identity of the sender which can show whether the text is stolen or misused, and find where the contents are tampered. The experiments show that multiple text watermarking algorithm can protect the data effectively aiming at different purpose which achieves its application value. Those also show the validity of multiple text watermarking technique used in the reliable transmission of electric power system texts and that this technique has a vast application prospect.


Keywords: Text watermarking technique, Multiple watermarking, Power system, Content authentication, Semi-fragile watermarking, Robustness watermarking.
