This paper introduces a three-point biometric authentication system for a blockchain-based decentralized identity network. We use existing biometric authentication systems to demonstrate the unique noise fingerprints that belong to each individual human and the respective information leak from the biological characteristics. We then propose the concept of using unique thermal noise amplitudes generated by each user and explore the open questions regarding the robustness of unconditionally secure authentication.
