The method, program and information processing system secures data, and particularly security sensitive words, characters or data objects in the data, in a computer system with territorial, geographic and triggering event protocols. The method and system determines device location within or without a predetermined region and then extracts security data from the file, text, data object or whatever. The extracted data is separated from the remainder data and stored either on media in a local drive or remotely, typically via wireless network, to a remote store. Encryption is used to further enhance security levels. Extraction may be automatic, when the portable device is beyond a predetermined territory, or triggered by an event, such a "save document" or a time-out routine. Reconstruction of the data is permitted only with security clearance and within certain geographic territories. An information processing system for securing data is also described. |
