Towards an Ontology-Based Content Security Scheme

The openness of Internet leads to security problems of network, among which content security is an important problem. In order to solve the problem effectively, a security scheme of information content which based on content security ontology (CSO) is presented. CSO is extracted from a security kernel (SK) which is a lexicon of information security knowledge drawing out from general thesaurus and internet. The measures of CSO generation and SK extraction which are the key technologies in the scheme are also given in this paper.
