AI SECURITY & BIOMETRICS
The Threat of Deepfake Fingerprints
This paper demonstrates and validates a critical, previously theoretical threat: the creation of physical deepfake fingerprints from stolen templates to spoof commercial scanners. By leveraging generative AI (GenAI) to generate fingerprint images from templates, fabricating silicone replicas with a 3D resin printer, and successfully deceiving scanners, the research exposes a significant vulnerability. The low-cost, end-to-end attack pipeline—$440 for initial setup and $0.07 per replica—highlights its practicality and urgent need for enhanced biometric security measures.

75%
Average Success Rate in Spoofing Commercial Scanners
The deepfake fingerprint replicas achieved an average 75% success rate against two commercial fingerprint scanners (SecuGen HU20 and ZKTeco Live 20R), demonstrating a practical and severe threat to biometric authentication systems. This rate includes instances of complete failure, underscoring both the potential and limitations.

Affordable Fabrication: The Path to Physical Replicas
The attack pipeline leverages readily available and cost-effective technologies. An 8K 3D resin printer, costing approximately $400 USD, is used to produce high-fidelity molds with a 22-micron resolution. The silicone material (Siraya Tech Defiant 25) costs $30 per kilogram. After the initial setup, each individual deepfake fingerprint replica costs only 7 cents in materials, making the attack highly practical and accessible for adversaries.

Cost to Fabricate Each Deepfake Fingerprint Replica
Beyond the initial equipment cost, the material cost for each deepfake fingerprint replica is remarkably low at just 7 cents. This affordability significantly lowers the barrier to entry for potential adversaries, making this a widespread and accessible threat.
