nn said psychologically, the legend didn't believe that the bad old man in front of him could turn Lin Ge into himself one by one, but the bad old man made a few gestures on his face with his fingers, nodded frequently, and said something that he didn't understand but felt very professional.
NNN's current advanced facial recognition system and fingerprint recognition system are very difficult to hack. nnnn and Jiuqian Xiu has already mentioned in his remarks about the trend of facial contours, how to deceive the facial recognition system, etc., Jiuqian Xiu is talking about the head of the Tao, which makes the legend's heart bottomless, after all, this guy can be known as the most awesome god in the disguise world.
After the calculation of the Nine Thousand Cultivation, it was clear what materials were needed, and Gu Qiya immediately ordered the fat head and them to prepare everything that the Nine Thousand Cultivation needed.
Although Nnnn was flustered by this legend, he still didn't believe that Nine Thousand Xiu could copy his fingerprints. nnnn When Jiuqian Xiu took out the legend's finger to look at it, the legend couldn't help but speak: "This is impossible, you don't have high-tech things, how can you copy my fingerprints" nnnn must know that fingerprints are a form of proof that human activities are never mistaken, and it is said that the skin of a four-month-old baby already has lines.
In fact, fingerprints begin to be produced when the embryo is four months old, and it begins to form at about six months.
After the birth of the baby, with the increase of age, the lines of the NNNN fingerprint thickened and the area increased, but the morphological structure, distribution range and overall layout of the pattern were basically unchanged for life and had a high degree of stability. nnnn That's why all kinds of criminal investigation films can solve the case with the fingerprints left by the suspect, and the fingerprints didn't run.
The physiological characteristics of NNNN people include fingerprints, face shape, iris, hand shape, voice, etc.
Through comparison and research, scientists have concluded that it is far easier to verify identity through fingerprints than to verify other physiological characteristics, and it is also more stable and secure.
Although NNNN has a considerable level of cloning technology in these years, it is said that clones may not have the same fingerprints, because each fingerprint has several unique and measurable feature points, which ensure the uniqueness of the fingerprint.
NNNN This also shows that two fingerprints may have the same overall characteristics, but their detailed characteristics cannot be exactly the same. nnnn This is the reason why the legend does not believe in the Nine Thousand Cultivators. nnnn: "Fingerprints are really the hardest thing to copy.
Nine Thousand Xiu smiled slightly, when it came to this, he was a professional, he knew a lot more than the legend: "Each fingerprint has several unique, measurable feature points, and each feature point has about five to seven features, and our ten fingers produce at least four thousand nine hundred independently measurable features.
"The nnnn legend was stunned, what this guy said was too professional, he was the same as just now, he was also confused, but this was quite professional. nnnn "Because fingerprint patterns are not continuous, smooth and straight, but often interrupted, bifurcated or turned, these breakpoints, bifurcations and turning points are called feature points.
It is these features that provide confirmation of the uniqueness of the fingerprint.
Nine Thousand Xiu continued. nnnn Xu Yun and the others were also quite surprised, Jiuqian Xiu's professionalism in "copying others" had far exceeded their expectations.
"The most typical feature points are endpoints and bifurcation points, in addition to divergence points, isolated points, ring points, short lines, etc.
The wide variety of fingerprints is enough to show that fingerprint recognition is a more reliable way to identify.
You know, twins that cannot be distinguished by DNA identification can be distinguished by fingerprints.
The NNNN legend said with a look of surprise: "That's so difficult, how can you copy" NNNN "I have never studied fingerprint copying a long time ago, but then I watched a news, so I had a whim in this regard.
"Nine thousand cultivators: "It is said that a school in Australia, in order to prevent students from skipping class, installed a set of fingerprint attendance machines to urge everyone to attend class.
However, some students have come up with a way to use gummies to forge fingerprints in an attempt to deceive this high-tech system.
"nnnn sounds really reasonable, if you press the fingerprint on the gummy so that you can get an opposite fingerprint, and then press it repeatedly with two gummies, it seems that you can really copy a fingerprint. nnnnBut the problem is that the lines on a piece of gummy are very unclear, and the second copy is estimated to be difficult to fool the fingerprint machine.
The same is actually true for nnnn, which is very unreliable to fake fingerprints.
But it also shows that it is not impossible to copy fingerprints, and the students with big brains have done it. nnnn: "Gummies are unreliable, but gels are.
Nine Thousand Xiu smiled.
NNNN gel is an ingredient in gummies. nnnn: "You, you're whimsical," the legend shook his head in disbelief. nnnn: "I have successfully made a fake finger that can fool a fingerprint machine with gel before, and the success rate is more than 70%, although it is not 100%.
Nine Thousand Cultivators: "I only need to make three fake fingers to guarantee that one of them will be successful." nnnn legend shook his head: "It's impossible, it's not possible at all, it's just your theory" nnnn Gu Qiya was also surprised: "Uncle Jiu, how do you do this" nnnn "uses forensic methods to extract fingerprints, and then shoots them with a high-resolution camera, transmits them to the computer for various processing such as left and right and reversal, and then makes plates for fake fingers.
Jiuqian Xiu This is not just talking, he has done it, so he is very familiar: "The accuracy of the template directly affects the fidelity of the fingerprint."
Using a technique similar to that of a printed circuit board, the sample can have a slight protrusion to meet the requirements of the mold.
Finally, spread the gel on the template and you're good to go. nnnn Lin Ge exclaimed: "You are amazing, this is too powerful, right" nnnn "Of course, this method cannot deal with those powerful fingerprint readers that can recognize transparency, hardness, charge carrying, and bubble levels.
"So I've added some craftsmanship to this, I can perfectly cover your fingers with this made gel, even those fingerprint readers that can recognize transparency, hardness, charge carrying, and the level of the steam drum can also fool around." nnnn Lin Ge gave a thumbs up in admiration. nnnn Xu Yun was also amazed, this level is probably only something that he can do as the first person to disguise. nnnn It's just that it's not a good thing that this thing can be copied.,Sooner or later this thing will be popularized in this world.,In case you master this technology, you can easily copy fingerprints.,Everyone has to wear gloves when they go out and do everything.。
Once the fingerprint information leaked by NNNN 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 the fingerprint information of nnnn is leaked, or copied and used, the consequences will be unimaginable.
What is even more terrifying about NNNN is that fingerprint recognition has one of the biggest drawbacks compared with digital password recognition technology, that is, once the person's biometric characteristics are stolen or imitated, it is difficult to change their own characteristics like changing the password. nnnn so if this thing is stolen, hehe, it's not as simple as retrieving the ball password, the digital password is retrieved and changed, and the fingerprint is changed a little confused, he regrets that he didn't set the iris password, and that's because someone told him that the iris password was not safe, saying that there is now a technology that can produce an imitation artificial iris within ten minutes.
The NNNN principle is also very simple, the data generated when scanning the iris of the eye, through the study of patterns, textures, sizes and other information to create a unique iris code, once there is an information output, after 100 to 200 iterations of repetition, it can be easily made to imitate the iris. nnnn, so the legend believes in complex and unique "fingerprints", but he didn't expect that a bad old man in front of him could easily copy and get his fingerprints, nnnn knew that he should have set all kinds of biological passwords at the beginning, so that the passwords of his various bank accounts and company accounts could be considered safe.
NNNN is actually like this now, only by using multi-mode biometric technology can we solve the problem of all single-mode biometric systems.
After nnnn bought what the fat man needed, Jiuqian Xiu didn't waste any more time and started to do it immediately, which was a rather time-consuming manual work. isjgniitfreeti0:
