Method and system transacting data using verifiable claims
In general, embodiments of the invention relate to a method for transacting data. The method includes receiving a verification request from a data consumer, where the verification request specifies an object. The method further includes initiating servicing of the verification request using a verifiable credential, where the verifiable credential specifies a data broker service and the object, where the verifiable credential comprises a claim authorizing the data broker service to transact the object, and where the verifiable credential is issued by an owner of the object. The method further includes initiating transmission of the object to the data consumer based on the servicing of the verification request.
1. A method for transacting data, the method comprising:
receiving a verification request from a data consumer, wherein the verification request specifies an object;
initiating servicing of the verification request using a verifiable credential,
wherein the verifiable credential specifies a data broker service and the object,
wherein the verifiable credential comprises a claim authorizing the data broker service to transact the object,
wherein the verifiable credential is issued by an owner of the object; and
initiating transmission of the object to the data consumer based on the servicing of the verification request,
wherein the owner is a legal entity,
wherein the verifiable credential specifies a decentralized identifier (DID) associated with the owner, and
wherein the owner is associated with a second verifiable credential that binds the owner to the DID.
2. The method of claim 1 , wherein verifiable credential is issued by the owner.
3. The method of claim 1 , wherein servicing the verification request comprises verifying the verifiable credential and the second verifiable credential.
4. The method of claim 1 ,
wherein the DID is associated with a public key, and
wherein public key is part of a public-private key pair associated with the owner, and
wherein the DID and the public key are stored on a ledger.
5. The method of claim 4 , wherein the object is associated with a signature generated using a private key of the public-private key pair.
6. The method of claim 4 , further comprising:
prior to receiving the verification request:
obtaining, by a local data manager, the object;
identifying a data confidence fabric (DCF) pipeline; and
storing the object based on the DCF pipeline, wherein storing the object comprises signing the object using the private key.
7. The method of claim 6 , further comprising:
generating an object identifier for the object; and
storing the object identifier in the ledger.
8. The method of claim 6 , wherein the local data manager obtains the object from a sensor.
9. The method of claim 1 ,
wherein the data broker service is a second legal entity,
wherein the verification request specifies a second DID associated with the data broker service;
wherein the data broker service is associated with a third verifiable credential that binds the data broker service to the second DID.
10. The method of claim 9 ,
wherein a fourth verifiable credential specifies DID associated with the owner and the object,
wherein the fourth verifiable credential comprises a second claim establishing the owner as an owner of the object, and
wherein servicing the verification request comprises verifying the verifiable credential, the second verifiable credential, the third verifiable credential, and the fourth verifiable credential.
11. A system, comprising:
a data management system, comprising a processor, and configured to:
receive a verification request from a data consumer, wherein the verification request specifies an object;
initiate servicing of the verification request using a verifiable credential,
wherein the verifiable credential specifies a data broker service and the object,
wherein the verifiable credential comprises a claim authorizing the data broker service to transact the object,
wherein the verifiable credential is issued by an owner of the object; and
initiate transmission of the object to the data consumer based on the servicing of the verification request,
wherein the owner is a legal entity,
wherein the verifiable credential specifies a decentralized identifier (DID) associated with the owner, and
wherein the owner is associated with a second verifiable credential that binds the owner to the DID.
12. The system of claim 11 , wherein verifiable credential is issued by the owner.
13. The system of claim 11 , wherein servicing the verification request comprises verifying the verifiable credential and the second verifiable credential.
14. The system of claim 11 ,
a ledger operatively connected to the data consumer and the data broker service;
wherein the DID is associated with a public key, and
wherein public key is part of a public-private key pair associated with the owner, and
wherein the DID and the public key are stored on the ledger.
15. The system of claim 14 , wherein the object is associated with a signature generated using a private key of the public-private key pair.
16. The system of claim 14 , further comprising:
a local data manager configured to:
prior to the data broker service receiving the verification request:
obtain the object;
identify a data confidence fabric (DCF) pipeline; and
store the object based on the DCF pipeline, wherein storing the object comprises signing the object using the private key.
17. The system of claim 16 , wherein the local data manager is further configured to:
obtain the object from a sensor;
generate an object identifier for the object; and
store the object identifier in the ledger.
18. The system of claim 11 ,
wherein the data broker service is a second legal entity,
wherein the verification request specifies a second DID associated with the data broker service;
wherein the data broker service is associated with a third verifiable credential that binds the data broker service to the second DID.
