Biometric identification is the core technology of smart door locks. In recent years, its iteration speed has accelerated, and multi-modal fusion has become the mainstream industry solution, balancing security and convenience. Early single fingerprint recognition has gradually upgraded to a combined mode of "fingerprint + face + password + card + temporary password + mechanical key". High-end products further incorporate palm vein and finger vein recognition, forming a higher-level biometric authentication system. 3D structured light and ToF face recognition technologies have matured, effectively resisting attacks using photos, videos, and masks. The recognition speed has been increased to the millisecond level, and the success rate of unlocking in complex scenarios such as for the elderly, children, wet hands, and oily hands has been significantly improved. Vein recognition relies on subcutaneous blood vessel characteristics, offering advantages such as live detection, non-replicability, and strong stability, and is rapidly gaining popularity in the high-end market. To address the usage differences among family members, products have been specially optimized for situations such as shallow fingerprints, worn fingerprints, and facial occlusion, improving adaptability for all age groups. Meanwhile, biometric information is stored locally and not uploaded to the cloud, protecting privacy and security from the source. Technological upgrades have made unlocking faster, more natural, and safer, allowing users to unlock without deliberate coordination with the device, truly achieving "seamless access" and pushing the user experience of smart door locks to a new level.
