Abstract

The present disclosure relates to a trustworthy data exchange. Embodiments include receiving, from a device, a query, wherein the query comprises a question. Embodiments include identifying particular information related to the query. Embodiments include receiving credentials from a user for retrieving the particular information related to the query. Embodiments include retrieving, using the credentials, the particular information related to the query from one or more data repositories that are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database. Embodiments include determining, based on the particular information related to the query, an answer to the query. Embodiments include providing the answer to the device.

First claim

What is claimed is:

1. A computer-implemented method for a trustworthy data exchange, comprising:
receiving, from a device, a query, wherein the query comprises a question;
determining, based on the query, a trusted authority by which particular information related to the query is to be certified;
retrieving the particular information related to the query from one or more data repositories storing data verified by the trusted authority, wherein the one or more data repositories are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database;
determining, based on the particular information related to the query, an answer to the query; and
providing the answer to the device.

2. The computer-implemented method of claim 1 , wherein the query is received by capturing a bar code displayed on the device.

3. The computer-implemented method of claim 1 , wherein providing the answer to the device comprises:
displaying the answer to a user,
prompting the user to approve providing the answer to the device, and
upon receiving user approval, transmitting the answer to the device.

4. The computer-implemented method of claim 1 , further comprising establishing a shared secret with the device, wherein providing the answer is based on establishing the shared secret.

5. The computer-implemented method of claim 1 , wherein the query and the answer are exchanged with the device within a trusted environment in which communications with the device are assumed to be authentic.

6. The method of claim 1 , wherein the particular information comprises a dependency relationship with additional information stored in the one or more data repositories.

7. The method of claim 6 , further comprising resolving the dependency relationship based on the additional information prior to retrieving the particular information related to the query from the one or more data repositories.

8. A computer-implemented method for a trustworthy data exchange, comprising:
receiving, by a client device from a query device, a query, wherein the query comprises a question;
determining, based on the query, a trusted authority by which particular information related to the query is to be certified;
retrieving, by the client device, the particular information related to the query from one or more data repositories storing data verified by the trusted authority, wherein the one or more data repositories are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database;
determining, by the client device, based on the particular information related to the query, an answer to the query; and
providing, by the client device, the answer to the query device.

9. The computer-implemented method of claim 8 , wherein the query is received by capturing a bar code displayed on the query device.

10. The computer-implemented method of claim 8 , wherein providing the answer to the query device comprises:
displaying, by the client device, the answer to a user,
prompting, by the client device, the user to approve providing the answer to the query device, and
upon receiving user approval, transmitting, by the client device, the answer to the query device.

11. The computer-implemented method of claim 8 , further comprising establishing, by the client device, a shared secret with the query device, wherein providing the answer is based on establishing the shared secret.

12. The computer-implemented method of claim 8 , wherein the query and the answer are exchanged with the query device within a trusted environment in which communications between the client device and the query device are assumed to be authentic.

13. The method of claim 8 , wherein the particular information comprises a dependency relationship with additional information stored in the one or more data repositories.

14. The method of claim 13 , further comprising resolving, by the client device, the dependency relationship based on the additional information prior to retrieving the particular information related to the query from the one or more data repositories.

15. A system for a trustworthy data exchange, comprising:
one or more processors; and
a memory comprising instructions that, when executed by the one or more processors, cause the system to:
receive, from a device, a query, wherein the query comprises a question;
determine, based on the query, a trusted authority by which particular information related to the query is to be certified;
retrieve the particular information related to the query from one or more data repositories storing data verified by the trusted authority, wherein the one or more data repositories are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database;
determine, based on the particular information related to the query, an answer to the query; and
provide the answer to the device.

16. The system of claim 15 , wherein the query is received by capturing a bar code displayed on the device.

17. The system of claim 15 , wherein providing the answer to the device comprises:
displaying the answer to a user,
prompting the user to approve providing the answer to the device, and
upon receiving user approval, transmitting the answer to the device.

18. The system of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the system to establish a shared secret with the device, wherein providing the answer is based on establishing the shared secret.

19. The system of claim 15 , wherein the query and the answer are exchanged with the device within a trusted environment in which communications with the device are assumed to be authentic.

20. The system of claim 15 , wherein the particular information comprises a dependency relationship with additional information stored in the one or more data repositories.
