Abstract
An example method includes capturing, by an image capture device of a computing device, an image of a face of a user. The method further includes detecting, by the computing device, whether a distance between the computing device and an object represented by at least a portion of the image is less than a threshold distance, and, when the detected distance is less than a threshold distance, denying authentication to the user with respect to accessing one or more functionalities controlled by the computing device, where the authentication is denied independent of performing facial recognition based at least in part on the captured image.
Claims30
A method comprising:
- capturing, by an image capture device coupled to a computing device, an image of a face of a user;
- detecting, by the computing device, whether a distance between the image capture device and an object represented by at least a portion of the image is less than a threshold distance;
- and
- when the detected distance is less than the threshold distance, denying authentication of the user with respect to accessing one or more functionalities controlled by the computing device, wherein the authentication is denied independent of performing facial recognition based at least in part on the captured image.
A computing device comprising:
- at least one processor;
- and
- at least one image capture device,
- wherein the at least one image capture device is operable to capture an image of a face of a user, and
- wherein the at least one processor is configured to:
- detect whether a distance between the computing device and an object represented by at least a portion of the image is less than a threshold distance;
- and
- when the detected distance is less than a threshold distance, deny authentication of the user with respect to accessing one or more functionalities controlled by the computing device, independent of performing facial recognition based at least in part on the captured image.
A method comprising:
- capturing, by an image capture device coupled to a computing device, an enrollment image associated with an authorized user of the computing device;
- detecting, by the computing device, an estimated distance between the computing device and an object represented by at least a portion of the enrollment image;
- measuring, by the computing device, a first measured distance between the computing device and the object represented by at least the portion of the enrollment image;
- generating, by the computing device, a correction factor at least in part by dividing the first measured distance by the estimated distance;
- capturing, by the image capture device of the computing device, an authentication image;
- measuring, by the computing device, a second measured distance between the computing device and an object represented by at least a portion of the authentication image;
- dividing the second measured distance by the correction factor to obtain an expected actual distance;
- detecting an actual distance;
- determining whether the actual distance matches the expected actual distance;
- and
- when the actual distance does not match the expected actual distance, denying authentication to a user with respect to accessing one or more functionalities controlled by the computing device, wherein the authentication is denied independent of performing facial recognition based at least in part on the authentication image and the enrollment image.
