User verification using touch and eye tracking
View Patent ↗A method includes receiving at a processor, an indication of a user touching a point on a data entry device, receiving at the processor, an indication of a user gazing in a direction, and comparing via the processor the touched point and the gazing direction to a known touch point and gaze direction to verify the user is an authorized user.
1. A method comprising:
receiving at a processor, an indication of a user touching a point on a data entry device;
receiving at the processor, an indication of a user gazing in a direction; and
comparing via the processor the touched point and the gazing direction to a known touch point and gaze direction to verify the user is an authorized user, wherein the point on the data entry device comprises multiple ordered points on a touch screen display, and wherein the gazing direction comprises multiple ordered gazing directions and wherein the points and directions are intermixed in a specified order, and wherein upon receipt of indications in the specified order, access is granted to the user.
2. The method of claim 1 wherein each gaze direction corresponds to a gaze point on the data entry device.
3. The method of claim 2 wherein each gaze point on the data entry device comprises a displayed alphanumeric symbol.
4. The method of claim 3 wherein each alphanumeric symbol comprises a number representative of an order of touch and gaze points.
5. The method of claim 2 and further comprising beginning a window of time following receipt of a touch point, and determining whether the user has gazed at the gaze point within the window of time.
6. The method of claim 2 and further comprising verifying that the user is an authorized user when a touch point is touched at the same time that the user gazes at a gaze point.
7. The method of claim 1 wherein one gaze direction corresponds to a point outside an area of the data entry device.
8. A machine readable storage device having instructions for execution by a processor of a machine, the instructions comprising instructions to perform:
receiving at a processor, an indication of a user touching a point on a data entry device;
receiving at the processor, an indication of a user gazing in a direction; and
comparing via the processor the touched point and the gazing direction to a known touch point and gaze direction to verify the user is an authorized user, wherein the point on the data entry device comprises multiple ordered points on a touch screen display, and wherein the gazing direction comprises multiple ordered gazing directions and wherein the points and directions are intermixed in a specified order, and wherein upon receipt of indications in the specified order, access is granted to the user.
9. The machine readable storage device of claim 8 wherein the gaze direction corresponds to a gaze point on a touch screen of the data entry device, wherein multiple touch points and gaze points are received, and further comprising:
verifying the user based on receiving indications of touching and gazing the points in the specified order;
beginning a window of time following receipt of a touch point; and
determining whether the user has gazed at one of the gaze points within the window of time.
10. A device comprising:
a processor; and
a memory device having a program stored thereon for execution by the processor to:
receive at the processor, an indication of a user touching a point on a data entry device;
receive at the processor, an indication of a user gazing in a direction; and
compare via the processor the touched point and the gazing direction to a known touch point and gaze direction to verify the user is an authorized user, wherein the point on the data entry device comprises multiple ordered points on a touch screen display, and wherein the gazing direction comprises multiple ordered gazing directions and wherein the points and directions are intermixed in a specified order, and wherein upon receipt of indications in the specified order, access is granted to the user.
11. The device of claim 10 and further comprising:
a camera coupled to provide the indication of the user gazing in the direction in the form of images of the user gazing; and
a housing to support the camera, processor, and memory, wherein the point on the data entry device comprises multiple ordered points on the data entry device and wherein the gazing direction comprises multiple ordered gazing directions, wherein the touch points and gaze points are intermixed in a specified order.
12. The device of claim 10 wherein the processor further comprising begins a window of time following receipt of a touch point, and determines whether the user has gazed at one of the gaze points within the window of time.
