Patent number: 10986087Abstract: A method for authenticating a user is presented. Responsive to a request for access to a computer resource, a computer system prompts the user making the request to access the computer resource to perform a new motion in an environment in which the user is monitored by a sensor system. Detected biometric data in the new motion performed by the user is identified by the computer system. A determination is made as to whether the user performing the new motion is an authenticated user based on comparing the detected biometric data with stored biometric data for a prior motion performed by the authenticated user. The computer system provides access to the computer resource when the user is identified as the authenticated user.Type: GrantFiled: July 17, 2018Date of Patent: April 20, 2021Assignee: International Business Machines CorporationInventors: Patrick Watson, Tengfei Ma, Maria Chang, Jae-Wook Ahn, Ravi Tejwani, Aldis Sipolins
