Abstract:
1. A computer-implemented method for locking a device, comprising: detecting, by a mobile device, distinct co-existing ambient wireless signals; measuring signal strength of a plurality of the distinct co-existing ambient wireless signals; calculating a first risk of theft of the mobile device based at least in part on the measured signal strength of the distinct co-existing ambient wireless signals; determining a first timeout time for the mobile device based at least in part on the risk of theft; determining an updated timeout time for the mobile device triggered by a change in the risk of theft of the mobile device, wherein upon a change in the risk of theft from the first risk of theft to a different risk of theft, the timeout time of the mobile device is amended from the first time out time to the updated timeout time; measuring an updated signal strength of the plurality of the distinct co-existing ambient wireless signals; calculating an updated risk of theft of the mobile device based at least in part on the updated signal strength; and amending the timeout time based at least in part on the updated risk of theft.
