Sensor data anomaly detector

A method to generate an alarm for a vehicle, the method comprising:

• receiving a sensor value from a sensor associated with the vehicle;
• determining a current mode of operation of a memory disposed in the vehicle, wherein the memory is configured to be in communication with the sensor;
• evaluating whether the sensor value corresponds to the current mode of operation of the memory;
• and
• generating the alarm, which indicates an error related to the sensor, in response to an evaluation that the sensor value does not correspond to the current mode of operation of the memory.

A system configured to generate an alarm for a vehicle, the system comprising:

• a sensor for the vehicle;
• and
• a processor in communication with the sensor, wherein the processor is configured to:
• receive a sensor value from the sensor;
• receive historical data that corresponds to the sensor;
• determine a difference between the sensor value and the historical data;
• determine, based on the difference, that the sensor value is outside a range which is associated with the sensor, wherein the range is based on the historical data;
• and
• transform the determination that the first sensor value is outside the range, into the alarm, to indicate that the sensor value is an anomaly.

A system to detect an attack on a vehicle, the system comprising:

• a sensor for the vehicle;
• and
• a processor in communication with the sensor, wherein the processor is configured to:
• receive a sensor value from the sensor;
• in response to the received sensor value, generate sample data to be written onto a memory which is disposed in the vehicle;
• attempt to write the generated sample data to the memory;
• detect an attack on the vehicle based on a determination that the attempt to write the generated sample data to the memory is unsuccessful;
• and
• generate an alarm that is indicative of the detected attack on the vehicle.

A system, comprising:

• a sensor for a vehicle;
• and
• a processor in communication with the sensor, wherein the processor is configured to:
• receive a sensor value from the sensor;
• determine a current mode of operation of a memory disposed in the vehicle,
• wherein the memory is configured to be in communication with the sensor;
• evaluate whether the sensor value corresponds to the current mode of operation of the memory;
• and
• generate an alarm that indicates an error related to the sensor, in response to an evaluation that the sensor value does not correspond to the current mode of operation of the memory.
