Directional touch unlocking for electronic devices

摘要

A system and machine-implemented method for matching input gestures on a touch interface to a security pattern to allow user access to an electronic device or account. The security pattern may correspond to a combination of linear and non-linear input gestures relating to directional changes of the input gestures. A determination of the security pattern may be based on the end motion and speed of each input gesture.

主权项

1. A computer implemented method, comprising:
receiving, by one or more processors, an input pattern from a touch based input device without providing a visual display of the input pattern, the input pattern comprising one or more directional changes corresponding to directional changes of user gestures made on the input device with a plurality of fingers; determining, by one or more processors, if the plurality of fingers matches a predetermined number of fingers, wherein the predetermined number of fingers is associated with a user's security profile; determining, by one or more processors, based on a speed of one or more of the user gestures, if the directional changes of the input pattern match directional changes of a security pattern associated with the user's security profile; and providing an unlock signal if the directional changes of the input pattern match the directional changes of the security pattern and if the plurality of fingers matches the predetermined number of fingers, the unlock signal granting user access to a user device or a user account.
