Abstract
Real human detection and confirmation in personal credential verification is described. In one example, a camera image of a user is received at a computer system. The image is tested for recognition against a user account and it is confirmed that the image corresponds to a real human. If the image is authenticated and corresponds to a real human, then the user is authenticated to the corresponding user account of the computer system.
Claims25
A method comprising:
- receiving a camera image of a face of a user at a face sensor of a computer system for use as face log in;
- testing the received camera image for recognition against a face image for a user account;
- providing a stimulus to the user from the computer system after recognizing the face image for a user account;
- determining whether an involuntary response to the stimulus by the user has been detected by the computer system;
- confirming that the image corresponds to a real face of a real human based on the determination;
- and
- if the image of the face is recognized and corresponds to a real human, then authenticating the user to the corresponding user account of the computer system.

A machine-readable non-transitory medium having instructions that when operated on by the machine cause the machine to perform operations comprising:
- receiving a camera image of a face of a user at a face sensor of a computer system for use as face log in;
- testing the received camera image for recognition against a face image for a user account;
- providing a stimulus to the user from the computer system after recognizing the face image for a user account;
- determining whether an involuntary response to the stimulus by the user has been detected by the computer system;
- confirming that the image corresponds to a real face of a real human based on the determination;
- and
- if the image of the face is recognized and corresponds to a real human, then authenticating the user to the corresponding user account of the computer system.
A computer system comprising:
- a camera to receive an image of a face of a user at the computer system;
- a memory to store a library of stored user face images in association with user accounts;
- a stimulus output to produce a stimulus to the user;
- a response sensor to detect an involuntary response by the user, if any, to the stimulus;
- and
- a processor to test the received face image for recognition against a face image of a user account of the memory to recognize the user and to confirm that the image corresponds to a real human based on the detected involuntary response, wherein if the image of the face is recognized and corresponds to a real human, then to authenticate the user to the corresponding user account of the computer system.
