Abstract
A method and apparatus for detecting preselected data embedded in information content is described. In one embodiment, the method comprises receiving information content and detecting in the information content a sequence of content fragments that may contain a portion of preselected data. The method further comprises determining whether a sub-set of these content fragments matches any sub-set of the preselected data using an abstract data structure that defines a tabular structure of the preselected data.
