Trusted device
First Claim
1. An apparatus comprising:
- circuitry to authenticate with an authentication operation a user having physical possession of said apparatus and thereby switch said apparatus to an authenticated state;
circuitry to continue to monitor physical possession of said apparatus by said user following said authentication operation, to continue said apparatus in the authenticated state if said apparatus is determined to remain in the physical possession of said user, and to switch said apparatus out of said authenticated state if said apparatus is determined to no longer be in physical possession of said user, wherein said circuitry to monitor physical possession of said apparatus includes detection circuitry to recognise one or more biometric characteristics of said user;
circuitry to detect a request to establish communication with a target device; and
circuitry to communicate with said target device when said apparatus is in said authenticated state.

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.

22. A method of trusted processing comprising the steps of:
-
authentication circuitry authenticating with an authentication operation a user having physical possession of an apparatus and thereby switch said apparatus to an authenticated state; detection circuitry continuing monitoring physical possession of said apparatus by said user following said authentication operation, continuing said apparatus in the authenticated state if said apparatus is determined to remain in the physical possession of said user, and switching said apparatus out of said authenticated state when said apparatus is determined to no longer be in physical possession of said user, wherein said monitoring physical possession of said apparatus comprises said detection circuitry recognising one or more biometric characteristics of said user; detecting a request to establish communication with a target device; and communication circuitry communicating with said target device when said apparatus is in said authenticated state.

23. A wristwatch comprising:
-
a display; circuitry to detect with an authentication operation a user having physical possession of said wristwatch and to switch said wristwatch to an authenticated state responsive to detecting said user having physical position of said wristwatch; circuitry to continue to monitor physical possession of said wristwatch by said user following said authentication operation, to continue said wristwatch in the authenticated state if said wristwatch is determined to remain in the physical possession of said user, and to switch said wristwatch out of said authenticated state when said wristwatch is determined to no longer be in physical possession of said user, wherein said circuity to monitor physical possession of said wristwatch includes circuitry to recognise one or more biometric characteristics of said user; circuitry to detect a request to establish communication with a target device; and circuitry to communicate with said target device when said wristwatch is in said authenticated state. - View Dependent Claims (24)
