How secure is fingerprint recognition?

Fingerprint recognition has high security, but it is not foolproof. Its security mainly depends on the following aspects:

1. Difficult to replicate

Fingerprints have uniqueness and stability. Compared to traditional password and pattern unlocking, fingerprint recognition is more difficult to forge. On the one hand, fingerprint images need to be collected through specific sensors, and high-precision replication requires professional equipment. On the other hand, certain devices, such as ultrasonic fingerprint sensors, also have the ability to detect blood flow and live features, further enhancing safety.

2. Encrypt storage and transmission

In smart devices, fingerprint data is usually not directly stored as an image, but is converted into feature data through hash functions or other encryption algorithms and stored in a secure area of the device (such as Apple's Secure Enclave or Android's Trust Zone). During each verification, the device compares real-time fingerprint data with stored feature data. The entire process adopts end-to-end encryption to ensure that data is not easily intercepted by hackers.

3. Prevent forgery attacks

Although fingerprint recognition has high security, it is not unbreakable. For example, early capacitive fingerprint sensors could be deceived through silicone models or fingerprint imitation. To cope with this type of attack, current sensor technology is constantly improving, not only adding live detection capabilities, but also combining other biometric features (such as facial recognition, iris scanning) for dual verification, thereby further enhancing anti-counterfeiting capabilities.

4. Impact of environmental factors

One issue with fingerprint recognition is the impact of the environment on its recognition accuracy. For example, when the user's fingers are wet, dry, dirty, or have wounds, the fingerprint image may not be fully captured, resulting in recognition failure. In this case, some devices allow users to set multiple fingerprints to increase the success rate of unlocking.
