Fingerprint recognition is widely used in door locks, smartphones, banking, government services, and other fields. However, many people overlook a critical issue: Is fingerprint data secure during collection, transmission, and storage?

Fingerprints are not like passwords—which can be changed if compromised. Once a fingerprint is compromised, it poses a lifelong risk.

Xinqihang’s glass-based encrypted fingerprint module applies a “security lock” to fingerprint data from the moment it is captured.

【First Layer of Security: Glass-Based Infrared Liveness Detection Ensures Authentic Fingerprint Capture】

Traditional software-based liveness detection relies solely on algorithms to analyze fingerprint image textures. High-fidelity biogel prosthetics can perfectly replicate skin elasticity, posing a risk of being bypassed. Glass substrates have high light transmittance and support infrared liveness detection—which determines whether the subject is alive by measuring the absorption rate of near-infrared light by oxygenated hemoglobin in the blood. Prosthetics cannot simulate the vital signals present in blood; only a real finger can proceed to the next step.

【Second Layer of Security: Encryption Upon Capture, End-to-End Data Protection】

Fingerprint data is encrypted the moment it is captured, preventing data leaks during the capture process. A dedicated encrypted channel is used during transmission to prevent data interception and tampering. Data is stored in encrypted form, ensuring it cannot be deciphered even if the storage medium is accessed without authorization. With end-to-end encryption from capture to application, we leave no room for vulnerabilities.

【Third Layer of Security: Hardware Security Chip + National Cryptographic Algorithms, Physical-Level Protection】

The module integrates a security chip with an independent encryption circuit, physically isolated from the fingerprint capture module. Data is transmitted to the chip for encryption immediately after capture. The security chip is resistant to physical attacks; even if the module is disassembled, it is difficult to obtain the encryption keys or fingerprint data. The encryption method used ensures that data cannot be deciphered by unauthorized access.

Fingerprints are encrypted upon capture, and the glass substrate adds a “security lock” to identity verification—ensuring that every fingerprint is trustworthy.

In the financial, government, and classified sectors, where information security requirements are highest, glass-based encryption modules are essential. Whether for large-value bank transfers, government system logins, access control at classified facilities, or data center management—every sensitive operation deserves this level of protection.
