Facial recognition authentication system including path parameters
Systems and methods for enrolling and authenticating a user in an authentication system via a user's camera of camera equipped mobile device include capturing and storing enrollment biometric information from at least one first image of the user taken via the camera of the mobile device, capturing authentication biometric information from at least one second image of the user, capturing, during imaging of the at least one second image, path parameters via at least one movement detecting sensor indicating an authentication movement of the mobile device, comparing the authentication biometric information to the stored enrollment biometric information, and comparing the authentication movement of the mobile device to an expected movement of the mobile device to determine whether the authentication movement sufficiently corresponds to the expected movement.
1. A method for authenticating a user via a user's camera equipped computing device, the method, during an authentication session comprising:
capturing at least one first image of the user taken with the camera of the computing device at a first distance from the user and processing said at least one first image to obtain first biometric data based on facial recognition data from the at least one first image;
moving the camera from a first location to a second location or the user moving from the first location to the second location to change the distance between the user and the camera from the first distance to a second distance;
capturing at least one second image of the user taken with the camera of the computing device at the second distance from the user, the second distance being different than the first distance, and processing the at least one second image to obtain second biometric data based on facial recognition data from the at least one second image;
comparing the first biometric data with first stored biometric data to determine whether the first biometric data matches the first stored biometric data;
comparing the second biometric data with second stored biometric data to determine whether the second biometric data matches the second stored biometric data, the second stored biometric data being distinct from the first stored biometric data; and
authenticating the user when:
the first biometric data matches the first stored biometric data and second biometric data matches the second stored biometric data; and
differences between the at least one first image and the at least one second image match expected differences resulting from movement of the camera from the first location to the second location or movement of the user from the first location to the second location, which causes the change in distance between the user and the camera.
2. The method according to claim 1 , further comprising:
interpolating the first stored biometric data and the second stored biometric data to obtain estimated intermediate biometric data;
capturing at least one third image of the user taken with the camera of the computing device at a third distance from the user, the third distance being between the first and the second distances, and processing the at least one third image to obtain third biometric data based on facial recognition data from the at least one third image; and
comparing the estimated intermediate biometric data with the third biometric data to determine whether the third biometric data matches the estimated intermediate biometric data.
3. The method according to claim 1 , further comprising verifying the presence of the user's ears in the at least one first image, and verifying the absence or reduced visibility of the user's ears in the at least one second image, wherein the first distance is larger than the second distance.
4. The method according to claim 1 , wherein the computing device is configured to display one or more prompts on a screen of the computing device to guide the user to capture the at least one first image and the at least one Off second image at the first and second distances.
5. The method according to claim 4 , wherein the one or more prompts are ovals sized on the screen within which the face of the user is placed to capture the at least one first image and the at least one second image at the first and second distances.
6. The method according to claim 4 , wherein the computing device is a hand-held device, and the user holds the device at the first and second distances to capture the at least one first and the at least one second images.
7. The method according to claim 6 , wherein the hand-held device comprises at least one of gyroscope, accelerometer, and a magnetometer, and the hand-held device captures movement information of the device as the hand-held device is moved from the first distance to the second distance.
8. The method according to claim 1 , further comprising displaying an image on a screen of the computing device while capturing the at least one first and/or the at least one second image, and processing the at least one first image and/or the at least one second image to detect a reflection of the displayed image off of the user's face.
9. The method according to claim 8 , wherein the image is a randomly determined color that is reflected off of the user's face or eye.
10. The method according to claim 8 , wherein the image is a coded image that is reflected off of the user's eye.
11. The method according to claim 10 , wherein the image is a bar code, and a reflection of the bar code off of the user's eye is detected in the at least one first image and/or the at least one second image.
12. The method according to claim 1 , wherein the first biometric data, the second biometric data, the first stored biometric data, and the second stored biometric data are maintained on the computing device.
13. A method for authenticating a user via a user's camera equipped computing device, the method, during an authentication session comprising:
capturing at least one first image of the user taken with the camera of the computing device at a first distance from the user and processing said at least one first image to obtain first biometric data based on facial recognition data from the at least one first image;
capturing at least one second image of the user taken with the camera of the computing device at a second distance from the user, the second distance being different than the first distance, and processing the at least one second image to obtain second biometric data based on facial recognition data from the at least one second image;
comparing the first biometric data with first stored biometric data to determine whether the first biometric data matches the first stored biometric data;
comparing the second biometric data with second stored biometric data to determine whether the second biometric data matches the second stored biometric data, the second stored biometric data being distinct from the first stored biometric data; and
authenticating the user when:
the first biometric data matches the first stored biometric data and second biometric data matches the second stored biometric data; and
the first biometric data does not match the second biometric data due to the change in distance between the user and the camera when capturing the at least one first image, at the first distance, and the at least one second image, at the second distance;
wherein the computing device is configured to display one or more prompts on a screen of the computing device to guide the user and frame the user's face within the prompts during capture of the at least one first image at the first distance and the at least one second image at the second distance.
