Abstract
Abstract A device and method for applying and retaining a unique data carrier to a tooth surface of an individual. The data carrier comprises a thin sheet of material having a data format unique to the individual. This data carrier is attached to the surface of the individual's tooth and is adapted for detection by a reader which can be operated by a third person. All phases of installation and detection of the carrier involve passive, noninvasive techniques which can be applied without regard to age and can be maintained as part of a permanent identification system. The system further comprises a central data bank which becomes a verification source for identifying information carried at the individual's tooth surface.
