Systems and methods for managing use of an imaging device

1. An image acquisition device comprising:

a computer-readable medium configured to store trust information, wherein the trust information is received from an identity provider in response to an establishment of a trust relationship with the identity provider;

an image detector configured to capture an image, wherein the captured image includes a credential image, and wherein the credential image includes a credential issued by the identity provider and generated by the identity provider in response to a user authentication; and

one or more processors configured to cause the device to perform operations including

receiving the trust information from an identity provider device;

capturing an image of a credential on a display medium, wherein the image of the credential was formed on the display medium by another device;

identifying the credential in the image of the credential;

determining if the credential is valid based on the trust information; and

allowing user initiation of one or more predetermined operations by the device in response to determining that the credential is valid or disallowing user initiation of the one or more predetermined operations in response to determining that the credential is invalid.

2. The device of claim 1 , wherein the image acquisition device includes one or more of a scanner, a camera, tablet PC, smartphone.

3. The device of claim 1 , wherein the one or more predetermined operations include one or more of printing, copying, faxing, and image capturing operations.

4. The device of claim 1 , wherein the credential includes one or more of a digital signature and a symmetric key.

5. The device of claim 1 , wherein the image acquisition device is configured to stop electronic communication with the identity provider after the trust information is received.

6. The device of claim 1 , wherein the image of the credential includes the credential in one or more of a one dimensional barcode and a matrix barcode.

7. The device of claim 6 , wherein the credential indicates one or more of a user identity, permissions, an expiration time, single use permission, multi-use permission, a device number, a list of permitted devices, a list of excluded devices, and a digital signature.

8. The device of claim 1 , wherein the image of the credential includes one or more of a watermark, a hologram, and microtext.

9. The device of claim 1 , wherein the processors are further configured to perform operations comprising refusing storage of the image of the credential.

10. A method for managing access to a device configured to capture images, the method comprising:

storing trust information at a first device configured to capture images, wherein the trust information is generated in response to the creation of a trust relationship with an identity provider;

capturing an image of indicia on a display medium with the first device configured to capture images, wherein the indicia are provided to a second device by the identity provider in response to a user authentication operation with the identity provider, and wherein the second device forms the image of the indicia on the display medium;

determining if the indicia are valid based on the trust information; and

allowing operation of other functions of the first device configured to capture images in response to determining that the indicia are valid or not allowing operation of the other functions of the first device configured to capture images in response to determining that the indicia are invalid.

11. The method of claim 10 , further comprising:

capturing an image of configuration indicia;

identifying the configuration indicia; and

accepting the trust information from an identity provider in response to identifying the configuration indicia.

12. The method of claim 11 , wherein the trust information includes at least one of a key and a certificate.

13. The method of claim 12 , wherein determining if the indicia is valid based on the trust information includes using a key to decrypt the indicia.

14. The method of claim 10 , further comprising receiving the trust information from the identity provider in response to a user authorization operation performed by the identity provider.

15. The method of claim 10 , wherein the display medium is one of a sheet of paper, a display, and a card.

16. One or more non-transitory computer-readable media storing instructions that, when executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:

receiving trust information from an identity provider;

capturing a first image of a credential on a display medium, wherein the first image was formed on the display medium by another device;

identifying a first credential in the first image that indicates the first credential; and

determining a user can initiate first one or more operations based on the first credential and the trust information or determining that the user cannot initiate the first one or more operations based on the first credential and the trust information.

17. The computer-readable media of claim 16 , wherein the first one or more operations are associated with first predetermined permissions, and wherein determining a user can initiate the first one or more operations based on the first credential includes determining that the first credential includes the first predetermined permissions.

18. The computer-readable media of claim 16 , wherein the operations further comprise:

identifying a second credential in a second image on a second display medium; and

determining a user can initiate one or more additional operations based on the second credential and the trust information or determining that the user cannot initiate the one or more additional operations based on the second credential and the trust information.

19. The computer-readable media of claim 16 , wherein the operations further comprise:

entering a configuration state in response to identifying configuration indicia in an image of the configuration indicia, wherein the trust information is received from the identity provider while in the configuration state; and

exiting the configuration state, wherein further trust information is not accepted while not in the configuration state.

20. The computer-readable media of claim 16 , wherein the operations further comprise:

determining a position of the first credential within the first image, and

determining if the position of the first credential is within a predetermined range of positions, and wherein

determining a user can initiate the first one or more operations is further based on whether or not the first credential is within the predetermined range of positions.
