Abstract

A computer-implemented method and apparatus allow for weighted voting in a public safety distributed ledger. A first node operating in a distributed ledger network receives an incident data record of one or more other nodes to maintain a distributed ledger. The first node reviews the incident data record to determine a vote. The vote indicates whether the incident data record should be entered into the distributed ledger. The vote is sent to a second node operating in the distributed ledger network. Votes are received from the one or more other nodes, and weights are determined for each node operating in the distributed ledger network node. A weighted vote result is calculated utilizing the votes and the weights. The distributed ledger is updated with the incident data record when the weighted vote result is greater than or equal to a predetermined threshold.

Claims

1. A computer-implemented method comprising:

receiving an incident data record at a first node operating in a distributed ledger network of one or more other nodes to maintain a distributed ledger;

reviewing at the first node the incident data record to determine a vote, the vote indicating whether the incident data record should be entered into the distributed ledger;

sending the vote to a second node operating in the distributed ledger network;

receiving votes from the one or more other nodes;

determining weights for each node operating in the distributed ledger network node;

calculating a weighted vote result utilizing the votes and the weights; and

updating the distributed ledger with the incident data record when the weighted vote result is greater than or equal to a predetermined threshold.

2. The computer-implemented method of claim 1, wherein the step of determining weights for each node operating in the distributed ledger network node comprises determining weights for each node operating in the distributed ledger network node based on parameters in the incident data record.

3. The computer-implemented method of claim 2, wherein the parameters include whether the incident data record relates to an incident that is within a predefined geographic distance from the agency.

4. The computer-implemented method of claim 2, wherein the parameters include whether the incident data record relates to an incident that is within a jurisdiction of the agency.

5. The computer-implemented method of claim 2, wherein the parameters include whether the agency operating the node in the distributed ledger network is the visiting agency for the incident.

6. The computer-implemented method of claim 2, wherein the parameters include whether the agency is the home agency for the incident.

7. The computer-implemented method of claim 2, wherein the parameters include whether the agency has greater than a predetermined threshold of resources assigned to the incident.

8. The computer-implemented method of claim 2, wherein the parameters include whether data in the incident record is evidentiary.

9. The computer-implemented method of claim 2, wherein the parameters include whether data in the incident record is public information.

10. The computer-implemented method of claim 1, wherein the step of determining weights for each node operating in the distributed ledger network node further comprises normalizing the weights.

11. The computer-implemented method of claim 1, the method further comprising the step of halting the step of receiving votes from the one or more other nodes upon expiration of a predetermined timer.

12. A computer apparatus comprising:

a communication interface;

one or more processors; and

a memory having executable code stored therein, wherein the executable code, when executed by the one or more processors, causes the one or more processors to;

receive an incident data record at a first node operating in a distributed ledger network of one or more other nodes to maintain a distributed ledger;

review at the first node the incident data record to determine a vote, the vote indicating whether the incident data record should be entered into the distributed ledger;

send the vote to a second node operating in the distributed ledger network;

receive votes from the one or more other nodes;

determine weights for each node operating in the distributed ledger network node;

calculate a weighted vote result utilizing the votes and the weights; and

update the distributed ledger with the incident data record when the weighted vote result is greater than or equal to a predetermined threshold.

13. The computer apparatus according to claim 12, wherein the first node is related to an agency, and wherein the incident data record includes parameters, the parameters including whether the incident data record relates to an incident that is within a predefined geographic distance from the agency.

14. The computer apparatus according to claim 12, wherein the first node is related to an agency, and wherein the parameters further include whether the incident data record relates to an incident that is within a jurisdiction of the agency.

15. The computer apparatus according to claim 12, wherein the first node is related to an agency, and wherein the incident data record includes whether the agency operating the node in the distributed ledger network is the visiting agency for the incident.

16. The computer apparatus according to claim 12, wherein the first node is related to an agency, and wherein the incident data record includes whether the agency is the home agency for the incident.

17. The computer apparatus according to claim 12, wherein the first node is related to an agency, and wherein the incident data record includes whether the agency has greater than a predetermined threshold of resources assigned to the incident.

18. The computer apparatus according to claim 12, wherein the incident data record includes whether data in the incident record is evidentiary.

19. The computer apparatus according to claim 12, wherein the incident data record includes whether data in the incident record is public information.
