US20190190896

1. A method of protecting data in a peer-to-peer distributed network having a set of computing entities, comprising: (3) (3)

associating at least respective first and second subsets of the computing entities into respective first and second blockchain channels, wherein a channel is a private subnet of communication between or among two or more specific peers in the respective subset for conducting one or more private transactions;

upon a determination that data associated with the first blockchain channel should be shared with the second blockchain channel, processing the data within the first blockchain channel according to a data protection policy to generate processed data; and

sharing the processed data to the second blockchain channel.

2. The method as described in claim 1 wherein the subset of the computing entities that comprise the first channel apply the data protection policy on sensitive data provided by one or more individual computing entities within the first subset. (1) (0)

4. The method as described in claim 1 further including selecting a computing entity in each subset as a leader for the respective channel. (1) (0)

7. The method as described in claim 1 wherein the respective first or second channel is created dynamically by associating the respective subset of computing entities upon a determination that one or more private transactions between or among the subset are required to be transacted. (0)

8. An apparatus, comprising: (3) (2)

a processor; and

computer memory holding computer program instructions executed by the processor and configured to protect data in a peer-to-peer distributed network having a set of computing entities, the computer program instructions comprising program code configured to: associate at least respective first and second subsets of the computing entities into respective first and second blockchain channels, wherein a channel is a private subnet of communication between or among two or more specific peers in the respective subset for conducting one or more private transactions;

upon a determination that data associated with the first blockchain channel should be shared with the second blockchain channel, process the data within the first blockchain channel according to a data protection policy to generate processed data; and

share the processed data to the second blockchain channel.

9. The apparatus as described in claim 8 wherein the subset of the computing entities that comprise the first channel apply the data protection policy on sensitive data provided by one or more individual computing entities within the first subset. (1) (0)

11. The apparatus as described in claim 8 wherein the computer program instructions further include program code configured to select a computing entity in each subset as a leader for the respective channel. (1) (0)

14. The apparatus as described in claim 8 wherein the respective first or second channel is created dynamically by associating the respective subset of computing entities upon a determination that one or more private transactions between or among the subset are required to be transacted. (0)

15. A computer program product in a non-transitory computer readable medium for use in a data processing system, the computer program product holding computer program instructions which, when executed by the data processing system, are configured to protect data in a peer-to-peer distributed network having a set of computing entities, the data processing system being a computing entity of the set of computing entities, the computer program instructions comprising program code configured to: (3) (3)

associate at least respective first and second subsets of the computing entities into respective first and second blockchain channels, wherein a channel is a private subnet of communication between or among two or more specific peers in the respective subset for conducting one or more private transactions;

share the processed data to the second blockchain channel.

16. The computer program product as described in claim 15 wherein the subset of the computing entities that comprise the first channel apply the data protection policy on sensitive data provided by one or more individual computing entities within the first subset. (1) (0)

18. The computer program product as described in claim 15 wherein the computer program instructions further include program code configured to select a computing entity in each subset as a leader for the respective channel. (1) (0)

21. The computer program product as described in claim 15 wherein the respective first or second channel is created dynamically by associating the respective subset of computing entities upon a determination that one or more private transactions between or among the subset are required to be transacted. (0)
