Abstract
A system of token-based user authentication for the purpose of authorizing user access to protected resources, such as web applications, computer systems or computer controlled devices. The system utilizes a personal trusted device (PTD), which is owned and operated by one specific user, to establish secure communication channels that are subsequently used to pass user credentials to authentication service. Association of a PTD with servers controlling access to resources is performed by publishing and capturing unique tokens via sensors embedded in PTD, such as an optical camera.
