Trusted device
First Claim
1. An apparatus comprising circuitry to:
- authenticate with an authentication operation a user having a physical relationship between said apparatus and said user, including said user having physical possession of said apparatus and thereby switch said apparatus to an authenticated state;
continue to monitor physical possession of said apparatus by said user following said authentication operation, so as to continue to keep the apparatus in said authenticated state if said apparatus is determined to remain in the physical possession of said user; and
switch said apparatus out of said authenticated state when said physical relationship between said apparatus and said user changes such that said apparatus is determined to no longer be in physical possession of said user.

Abstract
A trusted device, such as a wristwatch, is provided with authentication circuitry, used to perform an authentication operation to switch the trusted device into an authenticated state. Retention monitoring circuitry monitors the physical possession of the trusted device by the user following the authentication operation and switches the trusted device out of an authenticated state if the trusted device does not remain in the physical possession of the user. While the trusted device remains in the physical possession of the user, communication triggering circuitry is used to detect a request to establish communication with a target device that is one of a plurality of different target devices and communication circuitry is used to communicate with that target device using an authenticated identity of the user.

18. A method of trusted processing comprising the steps of:
-
authenticating with an authentication operation a user having a physical relationship between said apparatus and said user, including said user having physical possession of said apparatus and thereby switch said apparatus to an authenticated state; continually monitoring physical possession of said apparatus by said user following said authentication operation; continuing to keep said apparatus in said authenticated state while said apparatus is determined to remain in the physical possession of said user; and switching said apparatus out of said authenticated state when said physical relationship between said apparatus and said user changes such that said apparatus is determined to no longer be in physical possession of said user.

19. A wristwatch comprising:
-
a display; circuitry to detect with an authentication operation a user having a physical relationship between said wristwatch and said user, including said user having physical possession of said wristwatch and to switch said wristwatch to an authenticated state responsive to detecting said user having physical possession of said wristwatch; and circuitry to continue to monitor physical possession of said wristwatch by said user following said authentication operation; circuitry to continue to keep said wristwatch in said authenticated state if said wristwatch is determined to remain in the physical possession of said user; and circuitry to switch said wristwatch out of said authenticated state when said physical relationship between said wristwatch and said user changes such that said wristwatch is determined to be no longer, in physical possession of said user. - View Dependent Claims (20, 21)
