US Patent 8990914 Device, method, and system for augmented reality security

Devices and methods for authenticating a user of a mobile computing device to a content server include establishing a communication session between a target computing device and the content server that is identified by a session ID. The target computing device generates a pairing token using the session ID, which pairing token may be a two-dimensional bar code such as a quick response (“QR”) code, and presents the pairing token to the mobile computing device. The mobile computing device captures the pairing token and authenticates the user of the mobile computing device to an authentication server. The target computing device receives an authentication token from the authentication server in response to the mobile computing device successfully authenticating the user to the authentication server. The target computing device accesses content on the content server using the authentication token. Other embodiments are described and claimed.
