Paper Title: Proof of Authenticity of General IoT Information with Sensors and Blockchain

Paper Abstract: Authenticity of data in an IoT service cannot be assured if the service can release falsified information to users either intentionally or by accident. Applying blockchain in IoT is often referred to and even tested, but these systems just writes records as instructed, and there is a risk of falsified records being written. Thus, we propose a design in which tamper-evident and digitally signing sensors write digital evidence into a blockchain service in an atomic (indivisible) fashion, as they report sensor data. This allows integrity and confidentiality of the IoT information maintained throughout the system, even if the private keys or signature algorithms are compromised, or the public key certificates expire.
