Abstract: A system and method for validating an Internet of Thing (IoT) device on an IoT network. The IoT device captures and stores the historical sensor values, along with corresponding timestamps in a local memory. A controller receives the historical sensor values and also receives a heartbeat token over a network that is different than the IoT network. The controller calculates a historical hash value using the historical sensor value and the heartbeat token as inputs and stores the historical hash values and the corresponding timestamp in a blockchain ledger of an IoT management platform. At a later time, in response to a validation request from the IoT management platform, the controller polls the IoT device for the historical sensor value associated with a particular timestamp. The IoT device responds with the stored historical sensor value and the controller calculates a reconstructed hash value using the historical stored sensor value and a stored heartbeat token as inputs.
