System, device and method for securely transferring information from a hardware to a blockchain

Abstract

A data communication system for transferring data from a hardware unit to a blockchain or other distributed ledger. The system includes a hardware interface to connect to the hardware unit, and a device having a microcontroller, a secure element connected to the microcontroller, first communication module, and a communication protocol for enabling the microcontroller to communicate with the hardware interface through the first communication module. The microcontroller is configured to: read data from the hardware unit through the hardware interface; generate a transaction corresponding to the data; securely generate a blockchain private key (dB); digitally sign the transaction by a blockchain private key (dB); deliver the signed transaction, and then delete the blockchain private key (dB) from volatile memory of the hardware unit. The microcontroller is adapted to generate a blockchain private key (dB) from parameters contained in part from the device itself and in part from the hardware interface.
