Mobile machine with improved machine data authentication
A method of authenticating a robustly-identifiable system is provided. The method includes causing a processor of a mobile work machine to issue a challenge to a robustly-identifiable sensor module mounted relative to the mobile work machine. The method also includes receiving, by the processor of the mobile work machine, a response from the robustly-identifiable sensor module. The method also includes comparing, with the processor of the mobile work machine, the received response to an expected response to generate a match result. The method also includes selectively initiating trusted operation of the mobile work machine based on the match result.
1. A method of authenticating a robustly-identifiable system, the method comprising:
causing a processor of a mobile work machine to issue a challenge to a robustly-identifiable sensor module mounted relative to the mobile work machine;
receiving, by the processor of the mobile work machine, a response from the robustly-identifiable sensor module;
comparing, with the processor of the mobile work machine, the received response to an expected response to generate a match result; and
selectively initiating trusted operation of the mobile work machine based on the match result.
2. The method of claim 1 , and further comprising causing the processor of the mobile work machine to perform an initialization.
3. The method of claim 2 , wherein the initialization includes causing the processor to check its own robustly-identifiable function.
4. The method of claim 3 , wherein checking its own robustly-identifiable function includes challenging the processor and causing the processor to compare its own response to an expected response.
5. The method of claim 2 , wherein initialization employs a physically unclonable function.
6. The method of claim 1 , and further comprising:
causing the processor of the mobile work machine to issue a challenge to a robustly-identifiable location module;
receiving, by the processor of the mobile work machine, a response from the robustly-identifiable location module;
comparing, with the processor of the mobile work machine, the received response from the robustly-identifiable location module to an expected response to generate a location module match result; and
wherein selectively initiating trusted operation is also based on the location module match result.
7. The method of claim 1 , and further comprising:
causing the processor of the mobile work machine to issue a challenge to a robustly-identifiable communication module;
receiving, by the processor of the mobile work machine, a response from the robustly-identifiable communication module;
comparing, with the processor of the mobile work machine, the received response from the robustly-identifiable communication module to an expected response to generate a communication module match result; and
wherein selectively initiating trusted operation is also based on the communication module match result.
8. The method of claim 1 , wherein selectively initiating trusted operation of the mobile work machine based on the match result includes entering a failsafe mode based on a negative match result.
9. The method of claim 8 , and further comprising performing data capture in the failsafe mode.
10. The method of claim 9 , and further comprising providing an indication of failsafe mode.
11. A method of performing simultaneous machine data capture, the method comprising:
causing a processor of a mobile work machine to collect data;
causing the processor of the mobile work machine to watermark the collected data;
causing the processor of the mobile work machine to perform on-board data authentication of the watermarked data;
causing the processor of the mobile work machine to request third-party data authentication of the watermarked data; and
causing the processor of the mobile machine to transmit its on-board watermarked data.
12. The method of claim 11 , wherein the collected data is machine data.
13. The method of claim 11 , and further comprising causing the processor of the mobile work machine to store the watermarked data in an immutable ledger.
14. The method of claim 13 , wherein the immutable ledger is a blockchain.
15. The method of claim 11 , and further comprising providing an indication of whether the watermarked data failed authentication.
16. The method of claim 11 , and further comprising:
causing the processor of the mobile work machine to receive a third-party data transmission responsive to the third-party data authentication request;
causing the processor of the mobile machine to compare the on-board watermarked data with the third-party data transmission to determine whether the on-board watermarked data is discrepant; and
selectively using the watermarked, on-board data based on whether the on-board watermarked data is discrepant.
17. The method of claim 16 , wherein determining whether the on-board watermarked data is discrepant includes determining whether the on-board watermarked data is discrepant beyond a selected threshold.
18. The method of claim 16 , and further including causing the processor of the mobile work machine to generate a deviation signal based on whether the on-board watermarked data is discrepant.
19. The method of claim 18 , and further comprising causing the processor of the mobile machine to transmit the on-board watermarked data along with the deviation signal.
20. The method of claim 19 , wherein the deviation signal provides an indication relative to data confidence.
