Abstract

An electronic processor is configured to determine sensor data reliability at an incident scene for real-time and post-incident processing. The electronic processor receives primary sensor data from a primary data source, retrieves secondary data associated with the primary sensor data, calculates a reliability index for the primary sensor data using the secondary data; compares the reliability index to a threshold and one of executes a particular action and applies a particular policy as a function of the comparison.

Claims

1. A method comprising:

receiving, by an electronic processor, primary sensor data from a primary data source;

retrieving, by the electronic processor, secondary data associated with the primary sensor data;

calculating, by the electronic processor, a reliability index for the primary sensor data using the secondary data; and

comparing, by the electronic processor, the reliability index to a threshold and one of executing a particular action and applying a particular policy as a function of a comparison, such that;

when the reliability index is above the threshold, one or more of;

disseminating the primary sensor data to one or more of talkgroups and a computer aided dispatcher associated with public safety responders;

notifying specific public safety responders or applications that evidentiary level data is available for use; and

using the primary sensor data to trigger real-time actions associated with the public safety responders.

2. The method of claim 1, wherein the secondary data is data associated with an event and the secondary data is retrieved from one or more of the primary data source and a secondary data source.

3. The method of claim 1, wherein the retrieving comprises looking up, in a confirmation table, one or more secondary data sources associated with the primary sensor data from the primary data source, and retrieving the secondary data from the one or more secondary data sources.

4. The method of claim 3, further comprising filtering the secondary data with a time window including a first time during which the primary sensor data was created.

5. The method of claim 1, wherein the calculating comprises calculating the reliability index for the primary sensor data as a function of sensor properties of the primary data source and any secondary data sources associated with the primary sensor data.

6. The method of claim 5, wherein the sensor properties include one or more of the primary sensor data, the secondary data, a level of hardware security of the primary data source, a level of operating system security of the primary data source, a level of hardware security of a secondary data source, a level of operating system security of the secondary data source, a sensor integrity status, a sensor accuracy level, ownership of the primary sensor data and the secondary data, a domain associated with the primary sensor data, a domain associated with the secondary data, a type of area network associated with the primary sensor data and a type of area network associated with the secondary data.

7. The method of claim 1, wherein the calculating comprises using the secondary data to increase or decrease a value of the reliability index.

8. The method of claim 1, further comprising, when the reliability index is above the threshold:

digitally signing, by the electronic processor, the primary sensor data, a primary source identifier and the reliability index and uploading a digitally signed data associated with a first digital signature to an evidentiary repository.

9. The method of claim 1, further comprising, when the reliability index is above the threshold:

mapping the reliability index to one or more policies associated with a higher reliability index,

wherein the one or more policies associated with the higher reliability index includes policies for one or more of;

uploading, to an evidentiary repository, one or more of the primary sensor data and digitally signed data associated with a first digital signature;

disseminating the digitally signed data, the reliability index, and a first time during which the primary sensor data was created, to communication devices associated with specific public safety responders or applications;

notifying the specific public safety responders or the applications that the evidentiary level data is available for use; and

using the primary sensor data to trigger the real-time actions associated with the public safety responders.

10. The method of claim 1, wherein the secondary data is generated from a different type of sensor than a sensor generating the primary sensor data.

11. The method of claim 1, further comprising validating the primary sensor data with the secondary data filtered with a timestamp including a first time during which the primary sensor data was created.

18. The method of claim 1, further comprising:

when the reliability index is below the threshold, disseminating the primary sensor data to devices, associated with the public safety responders, within a given vicinity of the primary data source.

20. The method of claim 1, wherein the retrieving comprises looking up, in a confirmation table, one or more secondary data sources associated with the primary sensor data from the primary data source, and retrieving the secondary data from the one or more secondary data sources, wherein the secondary data is generated from a different type of sensor than a sensor generating the primary sensor data.

when the reliability index is above the threshold, one or more of;

disseminating the primary sensor data to one or more of talkgroups and a computer aided dispatcher associated with public safety responders;

notifying specific public safety responders or applications that evidentiary level data is available for use; and

using the primary sensor data to trigger real-time actions associated with the public safety responders.

13. The electronic processor of claim 12, wherein the secondary data is data associated with an event and the secondary data is retrieved from one or more of the primary data source and a secondary data source.

14. The electronic processor of claim 12, wherein the retrieving comprises:
