Abstract
An improved vehicle odometer is provided with an encoder and a microcontroller. The encoder has a unique key that configures an encryption algorithm. The encryption algo- rithm can be in the form of circuitry or software or any combination there between. The encoder receives a incre- ment signal from the vehicle indicating that the vehicle has traveled a pre-determined distance. The encoder then incre- ments the odometer-related value and then encrypts it with the encryption algorithm. The encoder then wraps the encrypted odometer-related value into a data packet with a serial number. Only a suitably equipped computing device, such as a microcontroller, identify and correctly decrypt and process the encrypted odometer-related value, thereby pre- venting the tampering of the vehicle’s odometer. 11 Claims, 9 Drawing Sheets dentify Device by 314 erial Number or by a Function of the Serial Number Discard Data and Publish Error Message Decrypt Encrypted dometer Value and ‘ransmit to Display Device
