Patent ID: 7796013

Claim:
A device activated by biometric authentication, comprising: a biometric sensor configured to measure a plurality of different specific, internal, physiological characteristics of a user, said biometric sensor comprising, an energy emitter configured to emit an electromagnetic energy signal toward said user, wherein said electromagnetic energy signal is configured to penetrate said user to measure one or more of said specific, internal, sub-epidermal physiological characteristics of said user, and an energy sensor configured to detect an electromagnetic energy signal returned from said user responsive to said emitted electromagnetic energy signal to thereby obtain a measurement of said one or more specific, internal, sub-epidermal physiological characteristics of said user; and a memory module in communication with said biometric sensor comprising a biometric profile of an authorized user of said device, wherein the device is configured to select a first one and a second one of said plurality of specific, internal, sub-epidermal physiological characteristics of said user, emit an electromagnetic energy signal from said electromagnetic energy emitter to measure said first specific, internal, sub-epidermal physiological characteristic, and said second specific, internal, sub-epidermal physiological characteristic, receive a returned energy signal comprising said measurements of said first and second specific, internal, sub-epidermal physiological characteristics of said user, determine a first biometric marker of said user using said measurement of said first specific, internal, sub-epidermal physiological characteristic, determine a second biometric marker of said user using said measurement of said second specific, internal sub-epidermal physiological characteristic, and generate an authentication signal if said first biometric marker and said second biometric marker match a biometric profile of an authorized user of said device.
