Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

WHAT IS CLAIMED IS:

1. An apparatus, comprising:

one or more processing elements configured to:

in a first mode of operation, authorize a first action based on a first type of authentication;

in response to detecting disclosure of a particular type of information by the apparatus, enter a second mode of operation, wherein, in the second mode of operation, the one or more processing elements are configured to request a user to perform a second type of authentication before authorizing the first action.

2. The apparatus of claim 1, wherein the first action is unlocking the apparatus, wherein the first type of authentication is biometric authentication and the second type of authentication requires manual entry of a passcode.

3. The apparatus of claim 1 , wherein the disclosure of the particular type of information is performed by a virtual assistant program.

4. The apparatus of claim 1, wherein the one or more processing elements include a secure circuit configured to control access to the particular type of information and wherein the apparatus is configured such that other processing elements in the apparatus are configured to communicate with the secure circuit via only a predetermined subset of circuitry included in the secure circuit, wherein hardware resources of the secure circuit, other than the predetermined subset of circuitry, are not accessible to other processing elements in the apparatus.

5. The apparatus of claim 4, wherein the first type of authentication is a biometric authentication and wherein the secure circuit is configured to control access to template information for one or more known users for comparison with input information for the biometric authentication.

6. The apparatus of claim 4, wherein the secure circuit is configured to issue a token to another processing element based on first type of authentication for the user and wherein the secure circuit is configured to invalidate the token in response to the disclosure of the particular type of information.

7. The apparatus of claim 6, wherein the other processing element is a secure element configured to perform payment transactions.

8. The apparatus of claim 1, wherein the disclosure includes display of information via a lock screen interface generated by the apparatus.

9. The apparatus of claim 1, wherein the disclosure includes physical removal of a storage element from the apparatus.

10. The apparatus of claim 1, wherein the particular type of information includes one or more of: an account name, a name, a username, medical information, or contact information.

11. The apparatus of claim 1, wherein the particular type of information includes information identifying a registered user of the apparatus.

12. A non-transitory computer-readable medium having instructions stored thereon that are executable by a computing device to perform operations comprising:

in a first mode of operation, authorizing a first action based on a first type of

authentication;

in response to detecting disclosure of a particular type of information by the computing device, causing the computing device to enter a second mode of operation, wherein, in the second mode of operation, the computing device requests a user to perform a second type of

authentication before authorizing the first action.

13. The non-transitory computer-readable medium of claim 12, wherein the first action is unlocking the apparatus via a lock screen, wherein the first type of authentication is biometric authentication and the second type of authentication requires manual entry of a passcode.

14. The non-transitory computer-readable medium of claim 12, wherein the disclosure of the particular type of information is performed by a virtual assistant.

15. The non-transitory computer-readable medium of claim 12, wherein access to the particular type of information is controlled by a secure circuit in the computing device, wherein other processing elements in the computing device are configured to communicate with the secure circuit via only a predetermined subset of circuitry included in the secure circuit, wherein hardware resources of the secure circuit, other than the predetermined subset of circuitry, are not accessible to other processing elements in the computing device.

16. The non-transitory computer-readable medium of claim 15, wherein the secure circuit is also configured to control access to biometric template information for one or more known users.

17. The non-transitory computer-readable medium of claim 15, wherein at least a portion of the instructions are executable by the secure circuit.

18. The non-transitory computer-readable medium of claim 12, wherein the first type of authentication is a biometric authentication and wherein the second type of authentication requires manual entry of an authentication credential.

19. A non-transitory computer readable storage medium having stored thereon design information that specifies a design of at least a portion of a hardware integrated circuit in a format recognized by a semiconductor fabrication system that is configured to use the design information to produce the circuit according to the design, including:

one or more processing elements configured to:

in a first mode of operation, authorize a first action based on a first type of authentication;

in response to detecting disclosure of a particular type of information by the circuit, enter a second mode of operation, wherein, in the second mode of operation, the one or more processing elements are configured to request a user to perform a second type of authentication before authorizing the first action.

20. The non-transitory computer readable storage medium of claim 19, wherein the one or more processing elements include a secure circuit configured to control access to the particular type of information and wherein the design is configured such that other processing elements in the design are configured to communicate with the secure circuit via only a predetermined subset of circuitry included in the secure circuit, wherein hardware resources of the secure circuit, other than the predetermined subset of circuitry, are not accessible to other processing elements in the design.

21. The non-transitory computer readable storage medium of claim 19, wherein the first type of authentication is a biometric authentication and wherein the second type of authentication includes manual entry of an authentication credential.

22. The non-transitory computer readable storage medium of claim 19, wherein the disclosure includes display of information via a lock screen interface generated by the circuit.
