Extending electronic ID information

1. A method of maintaining a plurality of different sets of data groups for virtualized credentials of a holder, comprising:

storing a first subset of the data groups according to a standard for storing data groups, wherein the standard verifies each data group in the first subset of data groups;

storing a second subset of the data groups as a plurality of auxiliary data elements that are separate from the first subset, wherein the auxiliary data elements are not directly accessible using the standard;

providing a custom data group in the first subset that verifies each of the auxiliary data elements; and

verifying at least one of the auxiliary data elements using the custom data group and verifying the custom data group using the standard.

2. The method, according to claim 1 , wherein using the standard includes providing a data group of the first subset of the data groups having a plurality of digitally signed hash values and wherein each of the values corresponds to other data groups of the first subset of the data groups.

3. The method, according to claim 2 , wherein the standard is ISO 18013.

4. The method, according to claim 2 , wherein the digital signature is provided by a party that is trusted by a relying party that receives data from the holder.

5. The method, according to claim 1 , wherein the auxiliary data elements are provided to a relying party according to a role of the relying party.

6. The method, according to claim 5 , wherein information indicating a role of the relying party is stored with the auxiliary data elements.

7. The method, according to claim 5 , wherein role information provided by the relying party is provided in a verifiable format.

8. The method, according to claim 7 , wherein the role information is one of: digitally signed or securely derived and determined by a mutual authentication algorithm between the relying party and the holder.

9. The method, according to claim 1 , wherein data for the custom data group includes a list of all of the auxiliary data elements and a hash of each of the auxiliary data elements.

10. The method, according to claim 1 , wherein at least some data that is common to a plurality of the auxiliary data elements is stored with the custom data group.

11. The method, according to claim 1 , wherein at least a portion of the virtualized credentials are stored in a license holder device.

12. The method, according to claim 11 , wherein the license holder device includes at least one of: a battery-powered fob, a smartcard, an SD memory, and a USB memory.

13. A non-transitory computer readable medium containing software that maintains a plurality of different sets of data groups for virtualized credentials of a holder, the software comprising:

executable code that stores a first subset of the data groups according to a standard for storing data groups, wherein the standard verifies each data group in the first subset of data groups;

executable code that stores a second subset of the data groups as a plurality of auxiliary data elements that are separate from the first subset, wherein the auxiliary data elements are not directly accessible using the standard;

executable code that provides a custom data group in the first subset that verifies each of the auxiliary data elements; and

executable code that verifies at least one of the auxiliary data elements using the custom data group and verifying the custom data group using the standard.

14. The non-transitory computer readable medium, according to claim 13 , wherein using the standard includes providing a data group of the first subset of the data groups having a plurality of digitally signed hash values and wherein each of the values corresponds to other data groups of the first subset of the data groups.

15. The non-transitory computer readable medium, according to claim 14 , wherein the standard is ISO 18013.

16. The non-transitory computer readable medium, according to claim 14 , wherein the digital signature is provided by a party that is trusted by a relying party that receives data from the holder.

17. The non-transitory computer readable medium, according to claim 13 , wherein the auxiliary data elements are provided to a relying party according to a role of the relying party.

18. The non-transitory computer readable medium, according to claim 17 , wherein information indicating a role of the relying party is stored with the auxiliary data elements.

19. The non-transitory computer readable medium, according to claim 17 , wherein role information provided by the relying party is provided in a verifiable format.

20. The non-transitory computer readable medium, according to claim 19 , wherein the role information is one of:

digitally signed or securely derived and determined by a mutual authentication algorithm between the relying party and the holder.

21. The non-transitory computer readable medium, according to claim 13 , wherein data for the custom data group includes a list of all of the auxiliary data elements and a hash of each of the auxiliary data elements.

22. The non-transitory computer readable medium, according to claim 13 , wherein at least some data that is common to a plurality of the auxiliary data elements is stored with the custom data group.

23. The non-transitory computer readable medium, according to claim 13 , wherein at least a portion of the virtualized credentials are stored in a license holder device.

24. The non-transitory computer readable medium, according to claim 23 , wherein the license holder device includes at least one of: a battery-powered fob, a smartcard, an SD memory, and a USB memory.
