Why is Face Recognition better than fingerprint or other biometrics? The short answer is that neither biometric identification method is definitively superior to the other. Each has its advantages and disadvantages that make them both suitable for different uses. You cannot currently enter a secure area like a bank or movie theatre without your face being scanned.
Advantages of Face Recognition
Face recognition offers several benefits. First and foremost, face recognition is not affected by gloves. Two words can sum up the main benefits of face ID over Touch ID: simplicity and convenience. Modern devices are easy to use. You need to open the laptop lid or pick up your phone, and face ID instantly confirms your identity and unlocks it.
A slightly less obvious benefit of face recognition is learning different faces based on captured data. This knowledge could be useful for tagging or grouping photos of the same person in the user’s cloud storage. It is very unlikely that someone could use your picture to unlock your phone with malicious intent, especially since modern 3D facial scanning technology has been developed.
Disadvantages of Facial Recognition
You must give up biometric information to use any biometric system. A malicious organization could misuse information about your likeness. A dictatorial government that denies personal freedom might also use this information to monitor the actions of its citizens.
Without some workaround (e.g., Apple’s flood illuminator), facial recognition does not work in darkness. Technically, facial recognition is imperfect and can sometimes be hampered by lighting conditions, makeup, eyewear or masks. It has not been able to cope with the current pandemic because of the numerous glitches. When the subject is wearing masks, even the most sophisticated facial recognition systems are notoriously unreliable.
Benefits of Fingerprint Recognition
The fingerprint is the most secure and oldest biometric identification method. It is difficult to duplicate the fingerprint pattern, and it is unlikely that someone else will have it. It has been around for a while, and the sensor technology that powers it is becoming more affordable. Even entry-level smartphones nowadays include a fingerprint sensor to allow biometric authentication and identification.
Modern fingerprint sensors have improved dramatically over the years in their ability to identify fingerprints quickly. Current fingerprint sensors can identify your fingerprint in fractions of a second.
Negatives of Fingerprint Recognition
Fingerprint recognition has one major drawback. It won’t work if you are wearing gloves. For accurate and fast readings, it is important to contact the sensor directly. For under-display fingerprint scanners, it is possible to forget the location of a sensor because it does not have tactile features. This problem can take a while to get used to and end up being slightly annoying. It is important to keep the sensor clean and free of oil or dirt, which can be a challenge if you use it several times throughout the day.
Which one is better – Face Recognition or Fingerprint?
Each system has its advantages and disadvantages, which can give it an edge in different situations. Facial recognition, for example, requires various workarounds to work in darkness or may completely fail if you wear a mask. In such cases, fingerprint works without any problems. On the other hand, while fingerprints might fail to identify someone wearing gloves, facial recognition will likely work flawlessly.
We believe that it is best to include both systems in a product. This inclusion will allow the end-user to choose their favourite system to use and provide additional redundancy if one of the systems fails.
