Brain activity as unhackable password: principles of biocryptography (legrandcontinent.eu)

• Current flaws: no continuous auth, biometric spoofing, quantum computer threat.
• Biocryptography uses EEG with non-reversible transformation and error correction.
• Continuous authentication and revocability via context change are key features.

"The article outlines three vulnerabilities in current cryptography: lack of continuous authentication, replicability of biometrics, and the future threat from quantum computers. It proposes biocryptography using EEG brain activity. Four principles are described: non-reversible transformation of EEG signal, error tolerance via Reed-Solomon codes, continuous authentication (multiple times per second), and revocability through context changes. The technology is at proof-of-concept stage, with challenges in miniaturization and mass adoption."
