In Hangzhou, a human-computer cross-dimensional confrontation was staged. The artificial intelligence bio-recognition robot “Ark†(Mark) and the water brother Wang Hao, who is known as the “Evil Eyeâ€, performed PK: face recognition on the net red face.
According to the British report, because the molecules in sweat are unique, sweat can unlock smartphones like fingerprints or facial recognition. Researchers claim that this technology may become a reality in the next five to 10 years.
From fingerprints and irises to face recognition, biometrics are accompanied by smartphones into the homes of people. From the vague and curious, people have gradually become the most fashionable experience. How many "passwords" does the human body hide? Are these "passwords" safe?
Face recognition is fast but not safeThe combination of biometrics and smartphones is now one of the coolest technologies. In the smartphones released this year, Samsung Note 8, IPhone X and other large-scale models are equipped with a face recognition system.
Dr. Wang Xiaopeng, a national expert on thousands of people planning and CEO of Beijing Shima Dahua, said that the advantage of face recognition is fast, but because of the small number of feature points, a high-definition image of PS can overcome the two-dimensional recognition system. This year's CCTV 3.15 party, the host with the support of on-site technical staff, only one viewer self-photographed, successfully broke the "face registration" face authentication system.
The Apple IPhone X just released uses an advanced 3D face recognition system. Recently, online exposure of a face mask printed by a security company in Vietnam using 3D has actually fooled its face recognition system and successfully unlocked it. This also proves that the face recognition system is not safe.
In the future, you can pay for a “look at†mobile phone.Iris and DNA recognition have the highest level of uniqueness and safety in biometrics.
"But the high cost of DNA identification and the complexity of technology have determined that it can't be used in consumer electronics at present." Wang Xiaopeng said that iris recognition is a non-contact recognition of living organisms compared to other biometric technologies. It has four characteristics: First, universality, everyone, regardless of age, skin color and environment; second, uniqueness, each person is different, more than 260 feature points, guarantee trillions of repetition rate; third is consistency, characteristics are not Will change, people will be shaped after 18 months of birth, lifelong unchanged; Fourth, it is difficult to fake, real living recognition, extremely difficult to copy and forge.
Early iris recognition was costly compared to other recognition technologies, but it has made a big breakthrough. This year, Wang Xiaopeng's interpretation research team participated in the Ministry of Public Security's “13th Five-Year Plan†national key research and development plan, and is the drafter and promoter of the domestic iris recognition technology industry standard. They have successfully developed a two-in-one mobile smart chip with highly integrated face recognition and iris recognition. Wang Xiaopeng said to the Science and Technology Daily reporter that maybe your next mobile phone will have a new two-in-one system, as long as you can take a look at it with a deep look.
Biometric technology blends or becomes a trendAccording to the latest foreign reports, Jan Halamek, an assistant professor at the State University of New York at Albany, has found a new way to unlock the phone - through sweat.
In this regard, Wang Xiaopeng believes that the researchers' understanding of this idea is also simple, the sweat watermarks secreted by each person are also unique, and smart phones or other wearable devices can continuously learn the specific biological information in these skin secretions, This establishes the ability to recognize the user's sweat to help the user unlock.
In recent years, biometrics technology has continued to evolve, and voiceprints and finger vein recognition have also entered people's sights.
"The so-called voiceprint is a sound wave spectrum that carries speech information displayed by electroacoustic instruments. It is very suitable for remote identity verification. Only a microphone or telephone or mobile phone can be used to remotely log in through the network." Wang Xiaopeng said.
However, the shortcomings of voiceprint recognition are also very obvious, and the requirements for the environment are very high. In noisy environments and mixed speech, voiceprints are not easy to obtain; human voices also change with age, physical condition, mood, etc.; Different microphones and channels can also have an impact on recognition performance.
In addition, last year's "May 1" Shennongjia scenic spot refers to the use of intravenous ticket checking machines, and the ticket inspection takes only 3 seconds, effectively alleviating the congestion at the peak of the scenic spot. According to reports, the finger vein check system uses the vein pattern image obtained by penetrating the finger near the infrared rays for personal identification.
The personal finger vein distribution map is obtained by the finger vein identifier, and the feature values ​​are stored. When comparing, the vein map is taken in real time, and the feature values ​​are extracted to match, thereby identifying the individual.
However, the current use of vein recognition in the market is not high, it also has the disadvantage of being difficult to circumvent. Since the collection method is limited by its own characteristics, it is difficult to miniaturize the product, and it is currently not highly integrated into mobile terminals such as mobile phones.
Wang Xiaopeng said that the future biometrics technology will complement each other's development, and the market prospect of biometric technology is still worth looking forward to.
