Abstract
Methods, devices, and systems are disclosed for altering a mobile electronic device's screen timeout based on a strength of ambient wireless signals. A ringtone can be altered in addition to the password timeout time. Signals may be recognized or unknown and the time out can be adjusted based on the determined risk associated with the signals.
Claims20
A computer-implemented method for locking a device, comprising:
- under the control of one or more computer systems configured with executable instructions,
- detecting, by a mobile device, ambient wireless signals, the ambient wireless signals directed to and originating from systems other than the mobile device;
- measuring signal strength of one or more of the ambient wireless signals;
- calculating a risk of theft of the mobile device based at least in part on the measured signal strength of the one or more of the ambient wireless signals;
- determining a timeout time for the mobile device based at least in part on the risk of theft;
- and
- setting a timeout function of the mobile device using the determined timeout time.
A mobile device, comprising:
- an antenna configured to receive ambient wireless signals, the ambient wireless signals directed to and originating from systems other than the mobile device;
- a signal measurement subsystem that provides a count of ambient wireless signals detected;
- and
- a lockout subsystem that determines a timeout time based at least in part on a the count of ambient wireless signals.
One or more non-transitory computer-readable storage media having collectively stored thereon executable instructions that, when executed by one or more processors of a computer system, cause the computer system to at least:
- measure, by a mobile device, strength of ambient wireless signals, the mobile device being an unintended recipient of the ambient wireless signals;
- calculate a risk of theft of the mobile device based at least in part on the measured strength;
- and
- revise a timeout function of the mobile device based at least on the calculated risk.
