A method and system for employing biometric data includes first and second user computing systems coupled to respective first and second biometric devices for generating biometric data. A first user of the first user computing system uses the first biometric device, thus causing a generation of first biometric data which is then used as a database index to locate and authorize access to a database zone exclusively dedicated to the first user. The first user can further access the database zone on the second user computing system, and authorize access to a portion of data within the database zone to a second user of the second user computing system.
