Data security system and method associated with data mining

A method of securing data and managing the separation of user-based communities of interest based upon a plurality of security levels in a computer system with memories designated as a remainder store and a plurality of extract stores, said data having one or more security sensitive words, data objects, characters or icons grouped in (a) subsets of extracted data and (b) remainder data, comprising:

• storing said extracted data and said remainder data in said extract stores and said remainder store, respectively;
• and,
• permitting reconstruction of some or all of said data via one or more of said subsets of extracted data and remainder data only in the presence of a predetermined security level of said plurality of security levels.

A computer readable medium containing programming instructions for securing data and managing the separation of user-based communities of interest based upon a plurality of security levels in a computer system with memories designated as a remainder store and a plurality of extract stores, said data having one or more security sensitive words, data objects, characters or icons grouped in (a) subsets of extracted data and (b) remainder data, the programming instructions comprising:

• storing said extracted data and said remainder data in said extract stores and said remainder store, respectively;
• and,
• permitting reconstruction of some or all of said data via one or more of said subsets of extracted data and remainder data only in the presence of a predetermined security level of said plurality of security levels.

An information processing system for securing data and managing the separation of user-based communities of interest based upon a plurality of security levels in a computer system with memories designated as a remainder store and a plurality of extract stores, said data having one or more security sensitive words, data objects, characters or icons grouped in (a) subsets of extracted data and (b) remainder data, comprising:

• means for storing said extracted data and said remainder data in said extract stores and said remainder store, respectively;
• and,
• means for permitting reconstruction of some or all of said data via one or more of said subsets of extracted data and remainder data only in the presence of a predetermined security level of said plurality of security levels.
