Abstract
A biometric sensor including: a transmitter configured to transmit electromagnetic waves between 1 GHz and 300 GHz; a receiver configured to receive the electromagnetic waves from the transmitter; and wherein the transmitter and receiver are positioned in relation to an object to be scanned such that the receiver receives reflected electromagnetic waves. A method for sensing including: transmitting electromagnetic waves between 1 GHz and 300 GHz to an object; receiving reflected electromagnetic waves from the object; analyzing the electromagnetic waves and reflected electromagnetic waves to determine a characteristic of interest associated with the object.
Claims10
A biometric sensor comprising:
- a transmitter configured to transmit electromagnetic waves between 1 GHz and 300 GHz;
- a receiver configured to receive the electromagnetic waves from the transmitter,
- wherein the transmitter and receiver are positioned in relation to a stationary object to be scanned such that the receiver receives reflected electromagnetic waves, and wherein the stationary object to be scanned is a palm of a human being;
- wherein the system is configured to apply signal processing algorithms to the received reflected electromagnetic waves in order to produce a three-dimensional scattered image of internal features of the palm and identify the human being;
- and
- a second biometric sensor for two-factor authentication, wherein the second biometric sensor is selected from a group consisting of an optical sensor, an infrared sensor, a laser sensor, a camera sensor or an ultrasonic sensor;
- wherein the internal features of the palm are different from one human being to another under the transmitted electromagnetic waves.
A method for sensing comprising:
- transmitting, by a transmitter, electromagnetic waves between 1 Ghz and 300 GHz towards a stationary object, wherein the stationary object is a palm of a human being;
- receiving, by a receiver, reflected electromagnetic waves from the palm;
- and
- analyzing the electromagnetic waves and reflected electromagnetic waves to produce a three-dimensional scattered image of internal features of the palm and determine a characteristic of interest associated with the palm, wherein the internal features of the palm are different from one human being to another under the transmitted electromagnetic waves;
- measuring the characteristic of interest associated with the palm via a second biometric sensor for a two-level check.
