Abstract: This paper gives the content of an effective network security model against the threat of the Internet which can effectively solve the problem of content security analysis of Internet content security model, including its core algorithm——SIOP algorithm, which used to transfer compare the characters comparison in the query into an idea of numerical computing, and there is no limit on words in length, more suitable for large-scale Internet content security analysis system. Results show that the algorithm is effectively feasible, and the query speed increases 160% compared with other relative algorithms.
