RAW SENSOR INPUT ENCRYPTION FOR PASSCODE ENTRY SECURITY

摘要

A method of encrypting sensor input entries for passcode entry security is disclosed. The method in one embodiment includes presenting a passcode entry interface on an electronic device for a user to input a passcode entry. The electronic device then receives an input event, which is indicative of at least part of the passcode entry by the user, from a sensor of the electronic device. The electronic device then encrypts a sensor value of the input event and transmits the encrypted sensor value to an external system over a network to cause the external system to decipher the passcode entry from the encrypted sensor value.
