【Abstract】 To protect the digital library,an intrusion detection system model for network database based on data mining algorithm with the notion of distance measure is proposed after introducing the technology of intrusion detection for database.The algorithm considers domain knowledge about the data structures and semantics encoded in a given database schema,also it is used to guide the search for frequent item sets describing the working scopes of users.Then the model is applied to the new solution to the protection of library database under the network environment.更多还原
