Remote monitoring of fuel consumption with repeated fuel consumption measurements stored in a removable memory device

A method of reporting fuel consumption, the method comprising:

• providing a vehicle having a fuel level monitor;
• repeatedly measuring fuel consumption by the vehicle with the monitor;
• providing a server operable to generate fuel consumption reports, and
• transmitting the fuel consumption measurements via a communication channel between the fuel level monitor and the server, wherein the communication channel is remote from the vehicle;
• securely storing the repeated fuel consumption measurements;
• providing a removable memory device;
• storing the repeated fuel consumption measurements on the removable memory device;
• securely connecting the removable memory device to the remote communication channel;
• and
• transferring fuel consumption measurements from the memory device to the server via the communication channel;
• providing the vehicle with OBD (On Board Diagnostics);
• verifying whether there is a wireless connection between the OBD and the server;
• sending calculated fuel consumption from the OBD to the server if there is a wireless connection;
• generating a report of the fuel consumption, and
• tamper proofing the reporting by performing;
• retaining on the server a reference frequency of the second signal;
• comparing the reference frequency to a measured frequency of the second signal measured over the first period of time, and generating a tamper-alert if the reference frequency substantially differs from the measured frequency.

• providing a server operable to generate fuel consumption reports;
• transmitting the fuel consumption measurements via a communication channel between the fuel level monitor and the server;
• providing communication modules;
• transmitting the data from the memory device and\or the sensor via the communication modules to the server, and
• tamper proofing:
• securely storing a first communication module identifier on the server;
• reading from the communication modules a second communication module identifier;
• sending the second communication module identifier, along with the calculated fuel consumption data, to the server;
• comparing the second communication module identifier to the first communication module identifier, and
• generating a tamper-alert if the second communication module identifier and the first communication module identifier are not identical.
