Dynamic unlock mechanisms for mobile devices

摘要

An access control application for mobile devices is provided. The access control application may be configured to generate a set of security tasks based at least in part on information corresponding to a user's interactions with the mobile device. An unlock screen of the mobile device may be triggered and a security tasks from the generated set of security tasks may be displayed through a user interface of the mobile device. The user's response to the security tasks may be obtained and a confidence score may be calculated, based at least in part on the response. The access control application may then determine, based at least in part on the score and one or more attributes of the environment, whether to unlock the mobile device or prompt the user to provide an additional response to another security task.

1. A computer-implemented method for unlocking functionality of a mobile device, comprising:
under the control of one or more computer systems with executable instructions,
obtaining information corresponding to interactions with applications executed on a mobile device, the applications lacking privileges to set unlock settings of the mobile device;generating a set of security tasks based at least in part on the interactions;detecting a trigger for displaying a user interface for unlocking the mobile device;selecting a security task from the set of security tasks;displaying the selected security task through the user interface, where the user interface requires a response to the security tasks before enabling use of the mobile device;receiving a response to the displayed security task;calculating a confidence score based at least in part on the response;determining, based at least in part on the calculated confidence score, to require a next response to the next security tasks prior to enabling use of the mobile device;displaying the next security task through the user interface; andunlocking the mobile device as a result of determining the next security task was completed successfully.
