USER AUTHENTICATION BASED ON PHYSICAL MOVEMENT INFORMATION

摘要

Techniques described herein may be used to implement a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) test that requires a user of a user device (e.g., a smartphone, a laptop computer, etc.) to physically move in a certain pattern. In one implementation, a user device may prompt the user to physically move the user device according to a specified pattern. As the user does so, sensors of the user device may detect the movements of the user, and cause the user to be authenticated based on the physical movements. In another implementation, a user device may request that the user make a physical gesture in front of the user device. In so doing, an infrared sensor of the user device may detect the user's movements, and the user device may cause the user to be authenticated based on the physical movements.

主权项

1. A method performed by a user device, comprising:
receiving, by the user device, a request from a user to access a service; providing, by the user device, the user with a prompt to physically move in accordance with an authentication pattern associated with gaining access to the service; sensing, by the user device, physical movements, corresponding to the authentication pattern, of the user; collecting, by the user device, movement information representing the physical movements of the user; providing, by the user device, the movement information to an authentication server; and receiving, by the user device, a notification that the user has been authenticated for the service based on the movement information.
