A-Live: Passive Liveness Detection via Neuromuscular Micro-Motion Signatures on Commodity Sensors

Mohammed Gharib, Sam Burns, Martin Zizi

Abstract

Liveness detection has evolved from a safeguard against presentation and replay attacks in biometric authentication to a broader requirement for distinguishing human users from non-human agents in modern digital systems. The emergence of generative and agentic AI further amplifies this need, positioning liveness as a fundamental security primitive. Existing approaches face key limitations, including reliance on explicit user interaction, specialized hardware, vulnerability to increasingly realis
