The application of multiple texts watermarking algorithm in the transmission of power information security under the Internet

As an important energy industry, the effective solution of the information security problem has become an important problem to be solved. In view of the information security problems in the transmission of power information documents, the multi text watermarking algorithm is introduced into the document protection of power system for the first time. Based on the Internet, taking the transmission of power equipment parameters in power system and the content authentication of sender as an example, the robust watermarking algorithm is used to communicate the parameters of the equipment, so that it can resist the various attacks during transmission. The fragile watermarking algorithm is used to verify the identity of the document to detect whether or not the document has been stolen or misused, and to tamper with the text content of the modified part. In this paper, the algorithm is simulated and attacked. The results show that the multiple watermarking techniques can be used for different purposes for data protection and implementation of covert communication, realize its value, proved the multiple watermark ability to improve the transmission of electric power information security under the internet.
