| abstract |
The method, program and information processing system involves filtering and securing data (security sensitive words-characters-data objects) in a source document. The adaptive filter uses a compilation of additional data (typically networked) and identifies the sensitive words/objects in the compilation of additional data, retrieves contextual, semiotic and taxonomic words/objects from the additional data compilation that are related to the sensitive words/objects. A filter is compiled with the retrieved data and the filter is used to extract sensitive words/objects and the retrieved data (words/objects) from the source document to obtain extracted data and remainder data therefrom. Contextual words related to the security sensitive words/objects are obtained based upon statistical analysis of the additional data compilation. Semiotic words related to the security words are synonyms, antonyms, and pseudonyms, syntactics relative to the target words and retrieved words, and pragmatics relative to the sensitive words and retrieved words as reflected in the compilation of additional data. |
