Abstract
Content filtering of data containers is based on defining content types, receiving identifiers of a set of rules applicable to each content type, and determining dependence of at least one rule on other rules. The identifiers are sorted into rule strata where rules within each rule stratum are independent of each other and rules within each rule stratum beyond a first stratum depend on at least one rule of at least one preceding rule stratum. Upon receiving a data container of multiple components from a network, a content type is determined for each component. Rules of rule strata specific to a content type of a component are applied starting with rules of a first rule stratum and proceeding sequentially to selected rules of succeeding rule strata. An apparatus for content filtering stores processor-executable instructions for arranging rules in rule strata and sequentially applies successive rules to data containers.
