Abstract

Methods, devices, and systems are presented for screen locking or delaying the screen locking of mobile devices, such as smart phones, based on whether the gait of the current user match that of its true, authorized owner. A user'"'"'s gait can be measured using accelerometers embedded in the device. Other movements, such as where a user normally goes to work, can be measured using GPS or other positional location data and used to lock or delay locking of the screen.

Claims

1. A method comprising:

receiving a first set of time series physical movement data of a mobile device, the first set of data acquired while a first user supports the mobile device;

comparing, using a processor, the first set of movement data with a second set of time series physical movement data of a second user;

assessing whether the first user is the second user based on the comparison of the first and second sets of movement data; and

performing an action based on the assessment.

2. The method of claim 1 further comprising:

locking a display on the mobile device based on an assessment that the first user is not the second user.

3. The method of claim 1 further comprising:

sending an authentication message based on an assessment that the first user is the second user.

4. The method of claim 1 further comprising:

receiving a first set of audio voice data from the mobile device, the first set of audio voice data acquired while the first user speaks into the mobile device; and

comparing the first set of audio voice data with a second set of audio voice data of the second user,

wherein the assessment is further based on the comparison of the first and second sets of audio data.

5. The method of claim 1 further comprising:

classifying movement represented by the first set of data as a user movement type and then selecting the second data set based on the user movement type.

6. The method of claim 5 wherein the movement represented by the first set of data is acquired while the first user is walking.

7. The method of claim 1 further comprising:

classifying movement represented by the first set of data as a support movement type and then selecting the second data set based on the support movement type.

8. The method of claim 7 wherein the movement represented by the first set of data is acquired while the first user is holding the mobile device in his or her hand.

9. The method of claim 1 wherein comparing includes parametric comparisons of the sets of movement data.

10. The method of claim 1 wherein the assessing comprises determining a numerical probabilistic estimate that the second user is the first user.

11. The method of claim 1 wherein the first set of physical movement data includes data from an accelerometer coupled to the mobile device.

12. The method of claim 11 wherein the first set of physical movement data includes data from multiple accelerometers coupled to the mobile device, the multiple accelerometers positioned orthogonal to one another within the mobile device.

13. The method of claim 11 wherein the accelerometer is within the mobile device.

14. The method of claim 1 wherein the first set of physical movement data includes data from a global positioning system (GPS) receiver or a cellular triangulation engine in the mobile device.

15. The method of claim 1 wherein the physical movement data includes data from a gyroscope or compass in the mobile device.

16. The method of claim 1 wherein the physical movement data comprise position, velocity, and acceleration data.

17. The method of claim 1 wherein the operations are performed in the order shown.

18. The method of claim 1 wherein each operation is performed by the processor operatively coupled to a memory.

19. A machine-readable storage medium embodying information indicative of instructions for causing one or more machines to perform the operations of claim 1.

20. A computer system executing instructions in a computer program, the computer program instructions comprising program code for performing the operations of claim 1.
