How does biometric technology work?

The working principles of biometric technology mainly include three steps: data collection, feature extraction, and comparison. First, the system needs to collect the user's biometric data through dedicated sensors. For example, in fingerprint recognition, the sensor captures the details of the fingerprint, including the direction of the ridges and the bifurcation points. This data is converted into a digital format for subsequent processing. Next, the system performs feature extraction on the collected data. This process involves extracting representative features from the raw data to facilitate subsequent comparison. In fingerprint recognition, the system extracts unique points in the fingerprint, such as the end points and bifurcation points of the ridges. Finally, the system compares the extracted features with the features stored in the database to determine the identity. If the comparison is successful, the system confirms the identity of the user.

Application scope of biometric technology

Biometric technology has a wide range of applications, encompassing security, finance, healthcare, transportation, and other fields. In the security sector, biometric technology is used in access control systems and surveillance systems to enhance safety.
