Abstract
Various embodiments of the invention may be used to verify that a person being authorized by biometric techniques to use a device is a living person and not some form of recording intended to spoof the system. Some embodiments may try to cause a change in a measured biometric feature, and compare images taken before and after the change to verify the change occurred. In some embodiments, multiple stages of verification may be used, either to increase the difficulty of spoofing the security system, or to provide different levels of security for different levels of access to the device's functionality.
Claims15
An apparatus comprising:
- an electronic device comprising a processor, a memory, and a camera, the device to determine whether a person attempting to use the device is authorized to use the device, wherein the device is to:
- receive a first input of a first type;
- perform a first analysis of the first input to determine if the person attempting to use the device is authorized to use the a first level of functionality in the device based on the first analysis;
- receive a second input of a second type different than the first type, wherein the second input is initiated via at least one of manual triggering by the person, automatic triggering by the device upon passing of a predetermined amount of time after the first input has been received, and monitoring of the person by the device via a secondary device;
- if the person is authorized to use the first level of functionality based on the first analysis, then perform a second analysis of the second input to determine whether the person is authorized to use the second level of functionality based on the second analysis;
- and
- comparing the first input with the second input to determine whether a change has occurred in an expected manner, and wherein the person has passed a verification procedure if the change has occurred in the expected manner, and wherein the person has failed the verification procedure if the change has not occurred in the expected manner,
- wherein the verification procedure is associated with authorization of the person, wherein the verification procedure to determine whether the first and second inputs are coming from a living person or a non-living thing including one or more of an audio recording, a video recording, an audio/video recording, and a still picture.

A method comprising:
- performing operations in an electronic device, the operations comprising:
- receiving a first input of a first type;
- performing a first analysis of the first input to determine if the person attempting to use the device is authorized to use the device based on the first analysis;
- receiving a second input of a second type different than the first type, wherein the second input is initiated via at least one of manual triggering by the person, automatic triggering by the device after upon passing of a predetermined amount of time after the first input has been received, and monitoring of the person by the device via a secondary device;
- if the person is authorized to use the device based on the first analysis, then performing a second analysis of the second input to verify whether the person is authorized to use the device based on the second analysis;
- and
- comparing the first input with the second input to determine whether a change has occurred in an expected manner, and wherein the person has passed a verification procedure if the change has occurred in the expected manner, and wherein the person has failed the verification procedure if the change has not occurred in the expected manner,
- wherein the verification procedure is associated with authorization of the person, wherein the verification procedure to determine whether the first and second inputs are coming from a living person or a non-living thing including one or more of an audio recording, a video recording, an audio/video recording, and a still picture.
5 more elements
At least one non-transitory machine-readable medium comprising instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving a first input of a first type;
- performing a first analysis of the first input to determine if the person attempting to use the device is authorized to use the device based on the first analysis;
- receiving a second input of a second type different than the first type, wherein the second input is initiated via at least one of manual triggering by the person, automatic triggering by the device after upon passing of a predetermined amount of time after the first input has been received, and monitoring of the person by the device via a secondary device;
- if the person is authorized to use the device based on the first analysis, then performing a second analysis of the second input to verify whether the person is authorized to use the device based on the second analysis;
- and
- comparing the first input with the second input to determine whether a change has occurred in an expected manner, and wherein the person has passed a verification procedure if the change has occurred in the expected manner, and wherein the person has failed the verification procedure if the change has not occurred in the expected manner,
- wherein the verification procedure is associated with authorization of the person, wherein the verification procedure to determine whether the first and second inputs are coming from a living person or a non-living thing including one or more of an audio recording, a video recording, an audio/video recording, and a still picture.
