Watercraft Position Verification Using Engine Data Correlation

The patent introduces engine data as an intermediary verification element. Instead of directly verifying GPS positional information, the system uses engine operation data (which is difficult to falsify and uniquely tied to the specific watercraft) as a mediator to indirectly verify the authenticity of positional information. The server compares engine data patterns with positional information to detect falsification, resolving the contradiction by adding a verification layer without requiring complex hardware changes.

The patent merges positional information and engine data into a single verification process at the server. Both types of data are transmitted together and processed in combination to determine authenticity. This approach maintains relative simplicity in data transmission while significantly improving the ability to verify genuineness, as the server can cross-reference engine operation patterns with positional data to detect falsification.

The patent extracts only the essential engine data parameters needed for verification (such as engine ID, operation status, and timing information) rather than transmitting complete engine datasets. This selective extraction approach enables the server to perform authenticity verification by comparing engine behaviors with positional behaviors while keeping data transmission volume at manageable levels.
