Abstract

A portable communication device (100, 300, 400, 500) comprises a fingerprint identification system (709) including a scanner (115) for scanning a fingerprint (123) of a finger (121) to generate an image of the fingerprint (123). In a first embodiment, the scanner (115) is positioned relative to a switch (201) on the device (100, 300, 400, 500) to permit the finger (121) to generate the actuation force for the switch (201) when the fingerprint (123) is positioned on the scanner (115). In a second embodiment, the scanner (115) is ergonomically positioned on a housing (113, 117, 119) of the device (100, 300, 400, 500) where the finger (121) or a thumb naturally rests on the housing (113, 117, 119) when the person holds the housing (113, 117, 119) while the device (100, 300, 400, 500) is in use. In a third embodiment, a transmitter (205) of the device (100, 300, 400, 500) transmits data representative of the image of the fingerprint (123) to a remote site (715) when data representative of the image of the fingerprint (123) does not match data representative of a reference fingerprint.

Claims

1. A cellular telephone comprising:

circuitry including;

a transmitter coupled to a microphone transducer, and

a receiver coupled to an earpiece transducer;

a housing for carrying the circuitry, the housing having a front surface disposed opposite a rear surface and a side surface disposed between the front surface and the rear surface, wherein the housing is adapted to be held by a hand, having fingers and a thumb, of a person against a head of the person to permit the person to listen to acoustic signals generated by the earpiece transducer in signal communication with the front surface and to generate acoustic signals for input into the microphone transducer in signal communication with the front surface while the cellular telephone is in use; and

a fingerprint identification system including a scanner for scanning an image of a fingerprint of a finger or the thumb of the hand, wherein the scanner is ergonomically positioned on the housing on any of the rear surface of the housing and the side surface of the housing where the finger or thumb naturally rests on the housing when the person holds the housing while the cellular telephone is in use.

2. A cellular telephone according to claim 1 wherein the fingerprint identification system further comprises:

a first memory device for storing data representative of the image of the fingerprint;

a second memory device for storing data representative of at least one fingerprint; and

a processor determining whether the data representative of the image of the fingerprint matches the data representative of the at least one fingerprint, wherein the processor places the circuitry in a first mode responsive to the input signal when the data representative of the image of the fingerprint matches the data representative of the at least one fingerprint.

3. A cellular telephone according to claim 2 wherein the processor permits the circuitry to operate in the first mode as long as the finger or thumb remains on the scanner.

4. A cellular telephone for sending and receiving information such as voice signals, the cellular telephone comprising:

a housing;

a transmitter carried by the housing, the transmitter for modulating and transmitting input information;

a receiver carried by the housing, the receiver for receiving and demodulating transmitted information;

a fingerprint identification security system carried by the housing, the fingerprint identification security system to detect authorized and unauthorized use of the cellular telephone, the fingerprint identification security system including;

a scanner for scanning a fingerprint of a finger to generate an image of the fingerprint,

a first memory coupled to the scanner for storing the image of the fingerprint,

a second memory coupled to the first memory for storing a reference fingerprint, and

control circuitry coupled to the first memory and the second memory, the control circuitry for determining whether the image of the fingerprint matches the reference fingerprint, wherein

when the image of the fingerprint matches the reference fingerprint, the control circuitry activates the cellular telephone for use, and

when the image of the fingerprint does not match the reference fingerprint, the control circuitry causes the cellular telephone to temporarily transmit the image of the fingerprint to a remote site and then deactivate the cellular telephone from use.

5. The cellular telephone as in claim 4 wherein a transmission of the image of the fingerprint to the remote site includes information pertaining to any of a geographic location of the cellular telephone and a date of the transmission of the image.
