You may have heard many times that the most secure password is a complex combination of uppercase and lowercase letters, numbers and symbols, but this means that you need to remember a long and difficult string of characters. In addition to remembering complex passwords, is there any other simpler and safer way to access the door? This requires understanding biometric technology.
One of the reasons why biometrics is so secure is that your features are unique, and these features become your password. However, in the carnival of this technological revolution, ordinary users are facing a dilemma: should they choose the convenient “password-free life” or sacrifice part of the experience for convenience? When we use fingerprints to pay for a cup of latte in a coffee shop, do we realize that the residual fingerprints may be maliciously collected? When the iris scanner in the airport security channel lights up red, how many people really understand the privacy protection mechanism of this technology?
The most common access control biometric technologies on the market currently include: fingerprint recognition, face recognition, palm print recognition, voice (voiceprint) recognition, palm vein recognition, etc.
Now let CASHLY Technology Company introduce to you the advantages and disadvantages of fingerprint recognition, face recognition, palm print recognition, voice (voiceprint) recognition, and palm vein recognition.
Convenience at your fingertips — fingerprint access control
As the earliest popular biometric recognition technology, fingerprint unlocking has almost reshaped the interaction habits of modern people. From smartphones to smart door locks, the 0.3-second response speed of capacitive sensors has swept traditional passwords into the dust of history. This technology confirms identity by identifying fingerprints.
However, this convenience hides many problems. When the clips in the movie are reflected in reality, the residual fingerprints may be collected by people, increasing the risk of fingerprint information exposure for ordinary users. But for most users, the real safety rule is simple. When using fingerprint payment in open places, develop the habit of wiping the sensor at will.
The double-edged sword of face — face recognition access control
In the early morning, office workers do not need to stop, the facial features captured by the camera will become a pass. This method without any operation is the magic of face recognition. When other technologies still need user cooperation, face recognition has achieved authentication by existence.
Behind the convenience and speed, there may often be huge hidden dangers. According to reports, static photos can crack more than half of the community access control systems, and dynamic videos can bypass 70% of attendance equipment. What’s more serious is that when facial data is associated with sensitive information, once leaked, it may become a precise ammunition for online fraud. While we are enjoying the convenience of the “face-scanning era”, are we turning our faces into digital currency for others to make profits?
Iris lock — iris recognition access control
Iris recognition technology, an authentication method known as the “crown of biometric technology”, relies on more than 260 quantifiable feature points in the human eye to construct an identity password that is 20 times more complex than fingerprints. Its anti-counterfeiting performance is so strong that even the iris patterns of identical twins can be accurately distinguished.
But the other side of the technical advantage is the application limitation. Compared with other identification methods, iris recognition is more technically difficult, and the cost of related products is also higher. It is limited to high-end fields such as finance and military industry, and ordinary consumers rarely see it. The stringent requirements for precise alignment during operation also discourage some users who are racing against time.
The password in the palm of your hand — palm vein access control
The subtlety of palm vein recognition is that it does not record fingerprints on the surface of the skin, but captures the vascular network half a millimeter below the skin. This “living password” cannot be peeped or copied.
Compared with other technologies, palm vein recognition technology has amazing anti-interference ability. Experimental data shows that even if there is dust or small wounds on the palm, there is a 98% recognition rate. What is more reassuring is that the vein pattern is stable and cannot be observed from the outside, which makes it an ideal choice for privacy protectionists. Moreover, the cost of palm vein is not high, making it an ideal choice for “biometric recognition” for ordinary users.
