Apparatus and method for electronic determination of system data integrity

A method comprising:

• receiving sensor data from at least one sensor for a system;
• determining a first value based on execution of a first model that operates on the sensor data and characterizes a relationship between inputs to the system and outputs from the system;
• determining a second value based on execution of a second model that operates on the first output;
• determining a sensor prediction value for the at least one sensor based on the first value and the second value;
• and
• determining whether the sensor data is valid based on the sensor prediction value.

A non-transitory computer readable medium having instructions stored thereon, wherein the instructions, when executed by at least one processor, cause a device to perform operations comprising:

• receiving sensor data from at least one sensor for a system;
• determining a first value based on execution of a first model that operates on the sensor data and characterizes a relationship between inputs to the system and outputs from the system;
• determining a second value based on execution of a second model that operates on the first output;
• determining a sensor prediction value for the at least one sensor based on the first value and the second value;
• and
• determining whether the sensor data is valid based on the sensor prediction value.
