Abstract
A system and method of, and a service that employs, user authentication each employs a bluecard created by the service and stored on a personal trusted device (PTD). The system includes the service and the bluecard. The bluecard includes a unique identifier derived from a hardware address of the PTD. The PTD and the service communicate with one another over a personal area network (PAN) during user authentication. The method includes creating the bluecard and pushing the bluecard onto the PTD using an object exchange (OBEX) protocol of the PAN. The service includes a terminal and the created bluecard. The terminal has the PAN that communicates with the PTD. The bluecard is subsequently sent to the service from the PTD for user authentication via the PAN.
Claims20
A user authentication system comprising:
- a service employing user authentication to allow a user in possession of a personal trusted device (PTD) to access the service;
- and
- a bluecard comprising a unique identifier derived from a hardware address of the PTD, the bluecard being generated by the service and stored in the PTD,
- wherein the PTD and the service communicate with one another over a wireless personal area network (PAN) during user authentication.
A method of user authentication, the method comprising:
- creating a bluecard, the bluecard comprising an identifier derived from a hardware address of a personal trusted device (PTD);
- and
- pushing the bluecard onto the PTD using an object exchange (OBEX) protocol of a personal area network (PAN),
- wherein the bluecard is stored by the PTD for later retrieval during user authentication.
A service employing user authentication to allow a user to access the service, the service comprising:
- a terminal having a wireless personal area network (PAN) that communicates with a personal trusted device (PTD) of the user;
- and
- a bluecard generated by the service and stored on the PTD using the wireless PAN, the bluecard comprising an identifier created from a hardware address of the PTD, wherein during user authentication, the user is authenticated with the service by the stored bluecard being transmitted to the terminal using the wireless PAN.
