Biometric "black technology" from idealization to reality
In today’s world, what was once considered “black technology†in movies is now becoming a part of daily life. Biometric technologies, such as facial recognition, have seen remarkable improvements in accuracy and are now rapidly entering the market. This evolution has made these once futuristic concepts accessible and practical for everyday use.
The journey of biometrics began over two decades ago with researchers like Shan Shiguang, who has dedicated 20 years to studying face recognition at the Chinese Academy of Sciences. In 2017, he witnessed a turning point—biometric technology, including facial recognition, entered a new era of commercial application.
One of the first real-world examples came in September 2017 when Alipay introduced facial payment at a KPRO restaurant in Hangzhou. Users could simply activate the feature on their mobile app to complete a transaction in under 10 seconds. Around the same time, Apple launched the iPhone X, featuring FaceID, which used 3D facial mapping to unlock devices.
Banks started implementing face-to-face withdrawals at ATMs, while unmanned supermarkets adopted facial recognition for check-ins and payments. Voice recognition also found its way into instant translation tools, and universities used iris recognition for student attendance systems. These developments marked a significant shift in how we interact with technology.
According to Shan Shiguang, the past few years have seen a surge in biometric accuracy thanks to advancements in deep learning. This has led to rapid productization, making biometrics more reliable and widely available.
While facial recognition is the most visible form of biometrics, other methods like fingerprint and iris scanning are equally important. The term “face brushing†is just one example of the broader biometric revolution that is reshaping security, finance, and daily interactions.
China’s rapid progress in biometrics isn’t accidental. Policies such as the “Call for Action Plan for Special Operations for Black Cards†pushed for real-name authentication, creating demand for secure identification. At the same time, the growth of China’s internet industry increased the need for better user authentication solutions.
This dual push from policy and market demand allowed China to leap ahead in biometric technology. Companies like Beijing University of Technology and UOB have become global leaders in voice and iris recognition, respectively.
As the market grows, so do the applications. From security to retail, biometrics are no longer isolated technologies but work together to enhance user experience. However, challenges remain, such as accuracy in complex environments or noise interference in voice recognition.
Despite these hurdles, the future looks promising. With China’s vast population and dynamic market, biometric technology is set to continue evolving. Imagine a world where you can shop, bank, and even access your home without a key—just by using your face, voice, or iris.
The integration of multiple biometric methods will define the next phase of identity verification. As research continues, the goal is to achieve seamless, accurate, and secure identification that feels natural and effortless.
In this fast-paced world, biometrics are not just about security—they’re about convenience, efficiency, and a smarter way of living. As the technology matures, it promises to transform our daily lives in ways we’ve only begun to imagine.
