Palm vein SDK LINUX

Product Overview

Palm print+palm vein dual-mode biometric technology is an identity authentication technology that combines the geometric texture features of palm prints with the vascular distribution features of palm veins;
As the core operating carrier of this technology, Linux mainly undertakes core functions such as low-level driver management, algorithm operation, device communication, and data security storage.
Simply put, a palm print vein recognition system based on Linux adapts the hardware driver of the collection device (palm print/vein sensor) to the Linux kernel, deploys core algorithms such as feature extraction, comparison, and encryption in Linux systems (such as embedded Linux and Linux servers), and ultimately achieves high-precision and high security identity verification.

特点

feature	specific instructions
High security (Linux enhanced)	Palm vein is an internal living-body feature (contactless and impossible to counterfeit, unlike fingerprints which are easy to copy). Combined with Linux system permission control and kernel-level encryption, it prevents leakage or forgery of feature data. Dual-modal verification of palmprint + vein reduces the error rate by more than 95% compared with single-modal verification.
Cross-platform & Stability	The open-source and customizable nature of the Linux kernel enables adaptation to hardware of different architectures such as x86 and ARM (e.g., embedded access controllers, industrial servers). Linux also has a far lower failure rate than Windows and delivers strong 7×24-hour running stability, making it suitable for security and industrial scenarios.
Low Resource Consumption	For embedded Linux devices (e.g., ARM-based access control terminals), the algorithm can be lightweight and tailored, occupying only a few dozen MB of memory. It runs without high-performance hardware, reducing hardware costs.
Data Privacy Compliance	Linux supports local storage of biometric features (no cloud upload required), meeting the requirements of "local storage and minimized collection" for biometric features specified in the Personal Information Protection Law.
Strong Environmental Adaptability	Palmprint and vein dual-mode complement each other: palmprint is less affected by dry or wet conditions, while vein is immune to epidermal wear (e.g., rough hands of workers). Linux also outperforms other systems in adapting to extreme environments such as high/low temperatures and electromagnetic interference, making it ideal for industrial and outdoor scenarios.

What problem is being solved

1. Pain Points of Traditional Identity Authentication

Replace passwords and card swiping: Solve issues such as easy password leakage, card loss or duplication, and proxy clocking (e.g., enterprise attendance, campus access control);

Replace manual verification: Solve problems of low efficiency and high error rates in manual identity checking (e.g., airport security checks, bank counter identity verification);

Adapt to industrial scenarios: Solve the problems of poor stability and frequent crashes of Windows systems in industrial environments, with stronger adaptability of Linux (e.g., authentication for operation authority of factory equipment).

2. Defects of Single-Modal Biometric Recognition

Solve problems of easy forgery and wear of fingerprints: Fingerprints are epidermal features, easily forged with silica gel, and severely worn for workers and the elderly; palm vein is an internal living-body feature that can only be recognized with a living body and blood flow, making forgery impossible;

Solve the problem that single-modal palmprint recognition is susceptible to environmental interference: Although palmprint is stable, extreme dryness or humidity may affect recognition rate. With the addition of vein recognition, dual-modal verification greatly improves pass rate and accuracy;

Solve privacy and environmental restrictions of face recognition: Face recognition easily leaks facial information and is affected by light and mask occlusion; palmprint + vein recognition requires no facial exposure and adopts contactless collection (some devices only need palm suspended scanning), providing higher privacy.

3. Specific Problems in Actual Scenarios

Security scenarios: Solve the problem of "one card for multiple people" in campus and building access control, and realize accurate living-body identity authentication;

Financial scenarios: Solve security issues in identity authentication at bank counters and ATMs, and prevent fraudulent use of others' bank cards or ID cards;

Industrial scenarios: Solve the problem of operation authority management for factory equipment, allowing only authorized personnel to operate high-risk equipment and avoid misoperation;

Government affairs scenarios: Solve the problem of low efficiency of identity verification in government service halls, quickly verify the identity of applicants, and reduce queuing time;

Medical scenarios: Solve the problem of management authority for hospital drugs and medical devices, prevent unauthorized personnel from accessing dangerous drugs, and protect patient privacy (no need to retain facial information).
