AIR PASSWORD – AN TWO FACTOR SECURE AUTHENTICATION SYSTEM

Abstract

Air Password is a multimodal authentication system combining facial recognition with air-written gesture passwords to deliver secure, contactless login. A facial recognition model performs real-time identity verification, followed by gesture tracking using landmark detection. Movement sequences are processed by an RNN, while a transfer learningbased CNN recognizes individual characters to reconstruct the password. Deployed on a Raspberry Pi for edge-based processing, the system offers low-latency, privacy-preserving, and spoof-resistant authentication suitable for embedded and secure access applications.
