Abstract

An example operation may include one or more of connect to a blockchain network of an ecosystem comprised of a plurality of consumer nodes, generate a universal unique identifier (UUID) associated with a user data attribute, execute a query request for the user data attribute associated with the UUID, derive a disclosure level from the query request, execute a smart contract to commit to a blockchain ledger, a monetary value associated with the user data attribute, negotiate a transaction with the consumer node to access the user data attribute and recording an agreement result onto the a blockchain ledger.

First claim

What is claimed is:

1 . A system, comprising:
a processor; a memory on which are stored machine readable instructions that when executed by the processor, cause the processor to:
connect to a blockchain network of an ecosystem comprised of a plurality of consumer nodes;
generate a universal unique identifier (UUID) associated with a user data attribute;
execute a query request for the user data attribute associated with the UUID, wherein the query request is received from a consumer node of the plurality of the consumer nodes;
derive a disclosure level from the query request;
execute a smart contract to commit to a blockchain ledger, a monetary value associated with the user data attribute based on the disclosure level;
negotiate a transaction with the consumer node to access the user data attribute and record an agreement result onto the a blockchain ledger; and
transfer the user data attribute to the consumer node upon detection of an asset transfer committed to the blockchain ledger.

2 . The system of claim 1 , wherein the instructions are further to cause the processor to execute a chaincode to generate a descriptive text to identify the user data attribute comprised of an identity data of the user.

3 . The system of claim 1 , wherein the instructions are further to cause the processor to generate the UUID by an invocation of a web service.

4 . The system of claim 1 , wherein the instructions are further to cause the processor to determine the disclosure level as a no access, a full access anonymization, or a partial access anonymization.

5 . The system of claim 1 , wherein the instructions are further to cause the processor to commit to a blockchain ledger a monetary value associated with the user data attribute through a commitment hash on the blockchain, wherein a commitment is stored on an external data store.

6 . The system of claim 1 , wherein the instructions are further to cause the processor to transfer the user data attribute to the consumer node by a transfer of a location of the user data attribute on an external data store.

7 . The system of claim 1 , wherein the instructions are further to cause the processor to receive the asset transferred from the consumer node for the user data attribute as a result of a secure multi-party computation.

8 . A method, comprising:
connecting, by a data owner node, to a blockchain network of an ecosystem comprised of a plurality of consumer nodes; generating, by the data owner node, a universal unique identifier (UUID) associated with a user data attribute; executing, by the data owner node, a query request received from a consumer node of the plurality of the consumer nodes for the user data attribute associated with the UUID; deriving, by the data owner node, a disclosure level from the query request; executing, by the data owner node, a smart contract to commit to a blockchain ledger a monetary value associated with the user data attribute based on the disclosure level; negotiating a transaction with the consumer node to access the user data attribute and recording an agreement result onto the a blockchain ledger; and transferring, by the data owner node, the user data attribute to the consumer node of the plurality of the consumer nodes upon a detection of an asset transfer committed to the blockchain ledger.

9 . The method of claim 8 , further comprising executing a chaincode to generate a descriptive text to identify the user data attribute comprised of an identity data of the user.

10 . The method of claim 8 , further comprising generating the UUID by an invocation of a web service.

11 . The method of claim 8 , further comprising determining the disclosure level as a no access, a full access anonymization, or a partial access anonymization.

12 . The method of claim 8 , further comprising committing to a blockchain ledger a monetary value associated with the user data attribute through a commitment hash on the blockchain, wherein a commitment is stored on an external data store.

13 . The method of claim 8 , further comprising transferring the user data attribute to the consumer node by a transfer of a location of the user data attribute on an external data store.

14 . The method of claim 8 , further comprising receiving the asset transferred from the consumer node for the user data attribute as a result of a secure multi-party computation.

15 . A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:
connecting to a blockchain network of an ecosystem comprised of a plurality of consumer nodes; generating a universal unique identifier (UUID) associated with a user data attribute; executing a query request received from a consumer node of the plurality of the consumer nodes for the user data attribute associated with the UUID; deriving a disclosure level from the query request; executing a smart contract to commit to a blockchain ledger a monetary value associated with the user data attribute based on the disclosure level; negotiating a transaction with the consumer node to access the user data attribute and recording an agreement result onto the blockchain ledger; and transferring the user data attribute to the consumer node of the plurality of the consumer nodes upon a detection of an asset transfer committed to the blockchain ledger.

16 . The non-transitory computer readable medium of claim 15 further comprising instructions, that when read by the processor, cause the processor to execute a chaincode to generate a descriptive text to identify the user data attribute comprised of an identity data of the user.

17 . The non-transitory computer readable medium of claim 16 further comprising instructions, that when read by the processor, cause the processor to generate the UUID by an invocation of a web service.

18 . The non-transitory computer readable medium of claim 15 further comprising instructions, that when read by the processor, cause the processor to determine the disclosure level as a no access, a full access anonymization, or a partial access anonymization.

19 . The non-transitory computer readable medium of claim 15 further comprising instructions, that when read by the processor, cause the processor to commit to a blockchain ledger a monetary value associated with the user data attribute through a commitment hash on the blockchain, wherein a commitment is stored on an external data store.

20 . The non-transitory computer readable medium of claim 19 further comprising instructions, that when read by the processor, cause the processor to transfer the user data attribute to the consumer node by a transfer of a location of the user data attribute on an external data store.
