Frankly speaking, Chuanchang didn't believe that the bad old man in front of him could transform Lin Ge into himself one to one. However, the bad old man made gestures on his face with his fingers several times, nodded frequently, and said something although he
I don’t understand the words but feel they are very professional.
Today's advanced facial recognition systems and fingerprint recognition systems are difficult to hack.
Jiu Qianxiu, however, had already mentioned in his remarks about facial contour trends, how to deceive facial recognition systems, etc. Jiu Qianxiu's words were clear and logical, which made Legend feel unsure. After all,
This guy is known as the most awesome person in the world of disguise.
After Jiu Qian Xiu's calculations, it became clear what materials were needed. Gu Qiya immediately ordered Fat Tou and the others to prepare everything needed by Jiu Qian Xiu.
Although Legend was flustered by this, he still did not believe that Jiu Qianxiu could copy his fingerprints.
When Jiu Qianxiu took out Legend's finger to look at it, Legend couldn't help but say: "This is impossible. You don't have high-tech things, how can you copy my fingerprints..."
You must know that fingerprints are a form of proof that human activities are infallible. It is said that the skin of a four-month-old baby already has lines.
In fact, fingerprints begin to appear when the embryo reaches four months of development, and begin to form around six months.
As the baby's age increases after birth, the lines of fingerprints thicken and the area increases. However, the morphological structure, distribution range and overall layout of the pattern remain basically unchanged throughout life and are highly stable.
This is why various criminal investigation films can solve crimes based on the fingerprints left by the suspects. The fingerprints have not escaped.
Human physiological characteristics include fingerprints, face shape, iris, hand shape, voice, etc. Scientists have concluded through comparison and research that authenticating identity through fingerprints is far easier than using other physiological characteristics to verify, and the stability and security are also higher.
.
Although cloning technology has reached a considerable level these days, it is said that clones may not necessarily have the same fingerprints because each fingerprint has several unique and measurable feature points, which ensure the uniqueness of the fingerprint.
This also shows that two fingerprints may have the same overall characteristics, but their detailed characteristics cannot be exactly the same.
This is the reason why Legend does not believe in Jiu Qianxiu.
"Fingerprints are indeed the most difficult thing to copy." Jiu Qianxiu smiled slightly. When it came to this aspect, he was a professional. He knew much better than Legend: "Each fingerprint has several unique and measurable characteristics.
points, and each feature point has about five to seven features, and our ten fingers produce at least 4,900 independently measurable features."
Legend was shocked. What this guy said was too professional. He listened in a daze just like before, but these words were quite professional.
"Because fingerprint lines are not continuous, smooth and straight, but often have interruptions, bifurcations or turning points. These breakpoints, bifurcation points and turning points are called feature points. It is these feature points that provide confirmation of the uniqueness of the fingerprint.
Information." Jiu Qianxiu continued.
Xu Yun and the others were also quite surprised. Jiu Qianxiu's expertise in "copying others" had far exceeded their expectations.
Jiu Qianxiu hasn't finished yet: "The most typical characteristic points are terminal points and bifurcation points. In addition, they also include divergence points, isolated points, loop points, short lines, etc. The wide variety of fingerprints is enough to show that fingerprint recognition is a more
A reliable method of identification. You must know that twins who cannot be distinguished by DNA identification can be distinguished by fingerprints.”
Legend said with a look of surprise: "That... is so difficult, how could you possibly copy it?"
"I had never studied fingerprint replication a long time ago, but then I saw a news, so I suddenly got an idea in this regard." Jiu Qian Xiudao: "It is said that a school in Australia installed a fingerprint attendance system to prevent students from skipping classes.
The government came to urge everyone to attend classes. However, there are policies and countermeasures, and some students actually came up with ways to use gummies to forge fingerprints in an attempt to deceive this high-tech system."
This really makes sense. If you press your fingerprint on a piece of gummy candy, you can get an opposite fingerprint, and then press it repeatedly with two pieces of gummy candy. It seems that you can really copy a fingerprint.
But the problem is that the pattern on a piece of gummy candy is very unclear, so it is unlikely that the second copy will be able to fool the fingerprint machine.
This is also true in reality. Forging fingerprints in this way is very unreliable. But it also shows that copying fingerprints is not impossible, and students with great imagination have solved the problem.
"Gummies are unreliable, but gels are okay." Jiu Qianxiu smiled.
Gel is an ingredient in gummies.
"Are you...are you fanciful?" Legend shook his head in disbelief.
"I have successfully used gel to make fake fingers that can fool fingerprint machines before. Although the success rate is not 100%, it is still over 70%." Jiu Qian Xiu said: "I only need to make three fake fingers.
With your fingers, you can guarantee that one of them will succeed."
Legend shook his head: "It's impossible... It's simply impossible. This is just your theory!"
Gu Qiya was also surprised: "Uncle Jiu, how do you do this?"
"Use forensic methods to extract fingerprints, then use a high-resolution camera to take pictures, transfer them to the computer for various processing such as left and right, inversion, etc., and then control the prosthetic finger." Jiu Qianxiu is not just talking, he
I have done it before, so I am very familiar with it: "The accuracy of the template directly affects the realism of the fingerprint. Using a technique similar to that of a printed circuit board, the sample pattern can have subtle bulges to meet the requirements of the mold. Finally, the gel is
Just lay it on the template.”
Lin Ge exclaimed: "You are doing something extraordinary, isn't it too powerful?"
"Of course, this method cannot deal with those powerful fingerprint readers that can identify transparency, hardness, charge carrying and bubble levels." Jiu Qian Xiu said: "So I added some craftsmanship to this, and I can make this
A good gel coats your finger perfectly, and even fingerprint readers that can detect transparency, softness, charge carrying, and steam bag level can get away with it.”
Lin Ge gave a thumbs up in admiration.
Xu Yun was also amazed. I am afraid that only the first person in disguise can achieve this level.
It's just that it's not a good thing that this thing can be copied. Sooner or later, this thing will become popular in the world. If everyone masters this technology and can easily copy fingerprints, everyone will have to wear gloves when doing anything outside.
Once the leaked fingerprint information is used by criminals, it will bring great harm to individuals and society. The uniqueness and uniqueness of fingerprints make them extremely important personal information, which can also be called personal privacy.
If fingerprint information is leaked or copied and used, the consequences will be disastrous.
What’s even more frightening is that fingerprint recognition has one of the biggest shortcomings compared to digital password recognition technology, that is, once the biometric characteristics of the person are stolen or counterfeited, it is difficult to change his own characteristics like changing his password.
So if this thing is stolen, haha, it won't be as simple as retrieving the Qiuqiu password. Just find the digital password and change it. How to change the fingerprint?
Legend was a little confused. He regretted that he had not set an iris password. That was because someone told him that the iris password was not safe. They said that now there is technology that can produce a replica artificial iris in ten minutes.
The reason is also very simple. The data generated when scanning the iris of the eye creates a unique iris code by studying information such as pattern, texture, and size. Once the information is output, after one hundred to two hundred iterations, it can be easily
Make fake iris.
So Legend believed more in complex and unique "fingerprints", but he didn't expect that a bad old man in front of him could easily copy his own fingerprints!
If he had known earlier, he should have set up various biometric passwords! Only then could the passwords for his various bank accounts and company accounts be considered safe.
In fact, this is really the case now. Only by using multi-mode biometric technology can we solve all the problems of single-mode biometric systems.
After Fat Tou bought what he needed, Jiu Qianxiu stopped wasting time and started working immediately! This is a very time-consuming manual work.
