<p>A method for applying an identification device upon the human body comprises the steps of: embedding a transducer (401) within a naturally-occurring fissure (201) in a tooth (202) and securing said transducer within said fissure using fissure sealant; then, obtaining identification data from the person by reading data from the transducer. The transducer could be a radio-frequency identification (RFID) device, and could include a Global Positioning function (GPS). The sealant could be a resin-based sealant or a glass ionomer-cement. The identification data could be obtained using a hand-held reading device 601.</p> |
