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 carries the mobile device;
receiving a second set of time series physical movement data of the mobile device, the second set of data acquired while a second user carries the mobile device;
comparing, using a processor, the first set of time series physical movement data with the second set of time series physical movement data;
determining a probability of whether the first user is the second user based on the comparison of the first and second sets of movement data;
assessing whether the first user is the second user based on the determined probability; and
performing an action based on the assessment.

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.

17. A machine-readable tangible storage medium embodying information indicative of instructions for causing one or more machines to perform operations 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 carries the mobile device; receiving a second set of time series physical movement data of the mobile device, the second set of data acquired while a second user carries the mobile device; comparing, using a processor, the first set of time series physical movement data with the second set of time series physical movement data; determining a probability of whether the first user is the second user based on the comparison of the first and second sets of movement data; assessing whether the first user is the second user based on the determined probability; and performing an action based on the assessment. - View Dependent Claims (18)

19. A computer system executing instructions in a computer program, the computer program instructions comprising program code for performing operations 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 carries the mobile device; receiving a second set of time series physical movement data of the mobile device, the second set of data acquired while a second user carries the mobile device; comparing, using a processor, the first set of time series physical movement data with the second set of time series physical movement data; determining a probability of whether the first user is the second user based on the comparison of the first and second sets of movement data; assessing whether the first user is the second user based on the determined probability; and performing an action based on the assessment. - View Dependent Claims (20)
