Abstract

A method, program and information processing system filters and secures 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, and retrieves contextual, semiotic and taxonomic words/objects from the compilation related to the sensitive words/objects. The resulting compiled filter is used to extract sensitive words/objects and 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 based upon statistical analysis of the additional data compilation. Semiotic words related 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.

Claims (150)

1. A method of filtering and securing from input data, one or more security sensitive words, characters or data objects with an adaptive filter in a computer system, said adaptive filter used in conjunction with a compilation of additional data, the method comprising:

identifying said security sensitive words, characters or data objects in said compilation of additional data;

retrieving at least one of contextual, semiotic and taxonomic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects;

compiling a filter with said security sensitive words, characters or data objects and the retrieved data related to said security sensitive words, characters or data objects; and

extracting, from said input data, with said filter, said security sensitive words, characters or data objects and said retrieved data to obtain extracted data and remainder data therefrom; and

storing either the extracted data separately from said remainder data or storing partial versions of said extracted data with said remainder data based upon multiple security levels unique to each partial version.

2. A method of filtering and securing data as claimed in claim 1 including conducting a network search through said compilation of additional data during the retrieval of data.

3. A method of filtering and securing data as claimed in claim 2 wherein retrieving includes retrieving contextual words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects based upon predetermined statistical analysis of said additional data relative to said security sensitive words, characters or data objects.

4. A method of filtering and securing data as claimed in claim 3 wherein retrieving includes retrieving semiotic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and the retrieval is based upon synonyms, antonyms, and pseudonyms of said security sensitive words, characters or data objects; syntactics of said security sensitive words, characters or data objects as reflected in said compilation of additional data; and pragmatics of said security sensitive words, characters or data objects as reflected in said compilation of additional data.

5. A method of filtering and securing data as claimed in claim 4 wherein retrieving includes retrieving taxonomic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and is based upon categorization and classification as reflected in said compilation of additional data and as related to said security sensitive words, characters or data objects.

6. A method of filtering and securing data as claimed in claim 5 wherein storing the extracted data separately from said remainder data is based upon multiple security levels.

7. A method of filtering and securing data as claimed in claim 1 wherein retrieving includes retrieving contextual words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects based upon predetermined statistical analysis of said additional data relative to said security sensitive words, characters or data objects.

8. A method of filtering and securing data as claimed in claim 1 wherein retrieving includes retrieving semiotic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and the retrieval is based upon synonyms, antonyms, and pseudonyms of said security sensitive words, characters or data objects; syntactics of said security sensitive words, characters or data objects as reflected in said compilation of additional data; and pragmatics of said security sensitive words, characters or data objects as reflected in said compilation of additional data.

9. A method of filtering and securing data as claimed in claim 1 wherein retrieving includes retrieving taxonomic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and is based upon categorization and classification as reflected in said compilation of additional data and as related to said security sensitive words, characters or data objects.

10. A method of filtering and securing data as claimed in claim 1 wherein retrieving includes retrieving contextual words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects based upon predetermined statistical analysis of said additional data relative to said security sensitive words, characters or data objects.

11. A method of filtering and securing data as claimed in claim 10 wherein retrieving includes retrieving semiotic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and the retrieval is based upon synonyms, antonyms, and pseudonyms of said security sensitive words, characters or data objects; syntactics of said security sensitive words, characters or data objects as reflected in said compilation of additional data; and pragmatics of said security sensitive words, characters or data objects as reflected in said compilation of additional data.

12. A method of filtering and securing data as claimed in claim 11 wherein retrieving includes retrieving taxonomic words, characters or data objects from said compilation of additional data related to said security sensitive words, characters or data objects and is based upon categorization and classification as reflected in said compilation of additional data and as related to said security sensitive words, characters or data objects.

13. A method of filtering and securing data as claimed in claim 12 wherein storing the extracted data separately from said remainder data is based upon multiple security levels.

14. A method of filtering and securing from input data, one or more security sensitive words, characters or data objects with an adaptive filter in a computer system, said adaptive filter used in conjunction with a compilation of additional data, the method comprising:

identifying said security sensitive words, characters or data objects in said compilation of additional data;

retrieving related data from said compilation of additional data representative of at least one of:

contextual characters or data objects related to said security sensitive words, characters or data objects;

semiotic words, characters or data objects related to said security sensitive words, characters or data objects;

taxonomic words, characters or data objects related to said security sensitive words, characters or data objects;

compiling a filter with said security sensitive words, characters or data objects and the retrieved data related to said security sensitive words, characters or data objects; and

extracting, from said input data, with said filter, said security sensitive words, characters or data objects and said retrieved data to obtain extracted data and remainder data therefrom; and

15. A method of filtering and securing data as claimed in claim 14 including conducting a network search through said compilation of additional data during the retrieval of data.
