Abstract
A method and system for filtering data in a network is provided. Initially a content type of data is determined, and if the content type is one of a number of predetermined content types, then a series of checks may be made. For example, the content syntax of the data may be determined and the content semantics of the data may be determined. The content syntax may be checked against a predetermined set of syntax rules corresponding to the predetermined content type and the content semantics may be checked against a predetermined set of semantic rules corresponding to the predetermined content type. If the content syntax and the content semantics satisfy the predetermined rules, then the data may be further processed. If the content syntax and the content semantics do no satisfy the predetermined rules, then the data may be discarded.
