16. The system of claim 15 wherein the data monitoring component comprises: a tokenizer to generate a first set of tokens from the first portion of the information content using an abstract data structure derived from the source data, and to generate a second set of tokens from an information content portion in a word-based language using natural delimiters; and a search engine, coupled to the tokenizer, to determine whether the first and second sets of tokens include fragments from any one or more rows from the source data.

The system of claim 16 further comprising a policy management system component, coupled to the data monitoring component, to create the abstract data structure by identifying a plurality of tokens within the source data based on the tabular format, for each token in a word-based language, creating a signature of a relevant token, and adding the signature to the abstract data structure, and for each token in the character-based language, creating a token delimiter indicator and a signature of a relevant token, and adding the token delimiter indicator and the signature to the abstract data structure.
