Fingerprints and human faces are important biological characteristics of human beings. The identity of a person can be quickly recognized through fingerprints or human faces, and the application scenarios are very wide. However, in some specific application scenarios such as access control systems, the access control equipped with fingerprint recognition has been quickly banned by the face recognition access control. So, what are the advantages of face recognition access control compared to fingerprint recognition access control? Is fingerprint access control useless? Let’s look at the following for a detailed analysis for everyone.
For example, for some elderly or children whose fingerprints are relatively shallow, the sensor is difficult to collect, resulting in a low recognition rate, and often requires multiple recognitions to successfully match and unlock. Or in autumn and winter, the fingerprint deformation caused by the peeling of the finger may also fail to reproduce the recognition. Wait for how much inconvenience these invisible bring to people.
It is worth mentioning that in 2018, it appeared that someone could easily open the fingerprint lock using orange peel. This kind of news suddenly exploded in the fingerprint door lock industry, and people had to have the security of fingerprint recognition door locks. question. The root cause of this embarrassing situation is the loophole caused by the algorithm. To this day, due to the update iteration of the algorithm, such low-level errors have been fixed. In addition, sensors that use live fingerprint recognition have been able to accurately recognize human fingerprints, and are now widely used in mobile phones and door locks.
In the current COVID-19 pandemic, in addition to quickly verifying identities, face recognition access control can also realize non-contact batch temperature measurement, which greatly improves the efficiency of traffic in some public places with heavy traffic, and there is no need to stop and wait in line. Manual temperature measurement reduces the risk of virus infection, and can be effectively managed, tracked and traced, which has brought outstanding contributions to epidemic prevention. This is also one of the main reasons why face recognition access control has been favored in the past two years. In addition, the access control equipped with face recognition can solve a series of inconveniences of traditional access control such as forgetting the key, IC card, and forgetting the unlocking password. It only needs to pass the face recognition to achieve identity verification.
Compared with fingerprint recognition access control, face recognition access control also has fatal flaws. That is, under overexposure, it cannot accurately recognize human faces. For example, when the sun is very high, looking directly at the sun will only feel a bright white in front of your eyes. Or when you use your mobile phone to take a photo with backlighting, the person you take is just a black outline that resembles a human shape. Such embarrassment also exists in face recognition access control, and there is no more perfect solution yet. In Zhilianda’s temporary solution, the real-time ambient light data is fed back to the software by installing a light sensor. The software adjusts the sensitivity of the camera in real-time and dynamically according to a preset algorithm to improve people in a backlit environment. The success rate of face recognition.
The answer is negative. Excluding the application scenario of access control, fingerprint recognition and face recognition are actually complementary. For example, the latest Iphone12 mobile phone does not have fingerprint recognition function. I want to unlock the phone when the lights are turned off at night. Face recognition cannot be used under weak light conditions. The user can only unlock the phone by entering a password. This design Widely criticized by consumers. In addition to basic face recognition, most domestic mobile phones are also equipped with under-screen fingerprint recognition. Even if face recognition cannot be used in a dark environment, the phone can be quickly resolved through fingerprints.
In summary, fingerprint recognition and face recognition have their own strengths in different application scenarios, and it is impossible to say that who can ban others. Although, in the application scenarios of access control, fingerprint recognition is indeed less popular than face recognition. What’s more, fingerprint recognition and face recognition can take the long and short and bring more convenience to human life.
