Abstract
Aspects of image capture challenge access are described. In one embodiment, an access service of a computing device directs an imaging system to capture an image including facial fiducial features and determine whether the features correspond to an expected set of features. The access service may also issue a request for a response including, for example, a request to tilt or move the computing device, move an individual's face, or contort an individual's facial features. After the request for the response, the access service may capture a response image. The response image may include an adjustment to facial fiducial features. The access service may further determine whether the adjustment to the facial fiducial features corresponds to the request. Depending upon whether the adjustment corresponds to the request, the access service may permit or deny access to features of the computing device.
