Patent ID: 10078743

Abstract:
A method for using a user device. The method includes obtaining, during a fingerprint learning phase, a historical portion of user activity data associated with user activity of a user using the user device, analyzing, by a computer processor of the user device, the historical portion to generate a fingerprint of the user, wherein the fingerprint represents characteristics of the user activity, obtaining, during a fingerprint matching phase subsequent to the fingerprint learning phase, an ongoing portion of the user activity data, analyzing, by the computer processor and based on the fingerprint, the ongoing portion to determine a match, wherein the match is determined at a time point within the fingerprint matching phase, and unlocking, by the computer processor and in response to determining the match, a locked data item for access, therein the locked data item is stored on the user device. The locked data item is associated to the user owning, assigned to, or normally and legitimately using the user device. In one embodiment, once unlocked the data item can be used to authenticate the user associated to it, i.e., the user owning, assigned to, or normally and legitimately using the user device on which the data item is stored.
