At the National Defense University Laboratory, we had the opportunity to experience a cutting-edge vein recognition device firsthand. Simply placing a finger on the scanner, the system automatically captured and registered the unique vein pattern in under 30 seconds. Then, when the same finger was placed again, the door unlocked instantly, confirming the identity with remarkable speed and accuracy.
Recently, the Digital Video Research Group at the School of Electronic Science and Engineering, National University of Defense Technology, has spent over a decade developing a highly advanced finger vein recognition and authentication system. This groundbreaking technology boasts an incredibly low false acceptance rate—just one in 100,000. The system has already secured five national invention patents, marking a significant breakthrough that challenges the previous dominance of Japan and South Korea in this field. Researchers are currently fine-tuning the product and plan to launch it commercially after the Spring Festival.
According to Xie Jianbin, the project leader, vein recognition is a relatively new biometric technology that offers greater security compared to traditional fingerprint scanning. It works by capturing the unique patterns of blood vessels under specific lighting conditions, making it a true "live detection" method. Unlike static fingerprint systems, this technology is more secure and can be applied in a wider range of scenarios.
In addition, the research team has been working on reducing the size of the device to enhance its usability. The reporter observed that the entire system stands only about 6 centimeters tall—roughly the size of a computer mouse—making it highly portable and convenient for everyday use.
Xie Jianbin also shared the future goals of the research team. “Our next phase will focus on two main areas: first, improving the system’s ability to extract vein features even in low-visibility conditions, thereby enhancing image clarity and detail. Second, we aim to strengthen the system’s adaptability to non-rigid targets, such as fingers that are bent or rotated, so that accurate identification remains possible in various real-world situations.â€
