Chapter 3880

The 303 chapter is terrible old man

Speaking of the psychological words, the legend does not believe that this bad old man can turn Lin Song one by one into himself, but this bad old man used his fingers to draw a few strokes on his face, nodding frequently, saying some Although he did not understand, he felt very professional.

Advanced facial recognition systems and fingerprint recognition systems are now difficult to invade.

However, Jiu Qianxiu has already mentioned in the speech about the contour of the face, how to deceive the knowledge of the facial recognition system, etc., the head of the nine thousand repairs is the road, which makes the legendary heart have no bottom, after all, This guy can be called the most powerful god in Yirongjie.

After nine thousand repairs, what materials are needed are also very clear, and Gu Yuya immediately fats them to prepare everything needed for the nine thousand repairs.

Although the legend is flustered, it still does not believe that the nine thousand repairs can copy his fingerprints.

When Jiujiu took out the legendary fingers and looked at it, the legend couldn’t help but say: “This is impossible. You don’t have high-tech things, how can you copy my fingerprints…”

It is important to know that fingerprints are a form of proof that human activities are never mistaken. It is said that the skin of a four-month-old baby has already been textured.

In fact, the fingerprints began to appear when the embryos developed to four months, and began to form in about six months.

After the baby is born, the fingerprints become thicker and the area increases with the increase of age. However, the morphological structure, distribution range and overall layout of the pattern are basically unchanged for life and have high stability.

This is why all kinds of criminal investigation films can solve the case with the fingerprints left by the suspects. The fingerprints did not run.

Human physiological characteristics include fingerprints, face shapes, irises, hand shapes, sounds, and the like. Scientists have compared and researched that fingerprint authentication is much easier than verification using other physiological features, and stability and security are higher.

Although the cloning technology has been quite standard in this year, the legendary clones may not have the same fingerprint, because each fingerprint has several unique and measurable feature points, which ensure the uniqueness of the fingerprint.

This also shows that the two fingerprints may have the same overall characteristics, but their detailed features may not be exactly the same.

This is the reason why the legend does not believe in the nine thousand repairs.

“Fingerprint is indeed the most difficult thing to copy.” Jiu Qian repaired a little smile. When it comes to this, he is professional. He knows more than the legend: “Each fingerprint has several unique, measurable features. Points, and each feature point has about five to seven features, and our ten fingers produce at least 4,900 independently measurable features.”

The legendary horror, this guy said that these are too professional, he is just as confused as listening to it, but this is quite professional.

“Because fingerprint lines are not continuous, smooth and straight, but often interrupted, bifurcated or turned. These breakpoints, bifurcation points and turning points are called feature points. It is these feature points that provide confirmation of fingerprint uniqueness. Information.” Jiu Qian repair continued.

Xu Yun They are also quite surprised. Jiujiu’s professionalism in “copying others” has far exceeded their expectations.

The nine thousand repairs have not been finished: “The most typical feature points are the termination points and the bifurcation points, in addition to the divergence points, isolated points, ring points, short lines, etc. The fingerprints vary widely, which is enough to show that fingerprint recognition is a more Reliable identification method. You must know that the DNA identification can not distinguish between twin, but it can be distinguished by fingerprint.”

The legend opened in amazement: “That… so hard, how can you copy it?”

“I have never studied fingerprint copying a long time ago, but then I read a news, so I have a whimsy in this regard.” Nine thousand monks said: “It is said that a school in Australia, in order to prevent students from skipping classes, installed a set of fingerprint attendance. The machine urged everyone to take classes. However, there are countermeasures under the policy. Some students have tried to use fake candy to fake fingerprints in an attempt to fool this high-tech system.”

This is really quite reasonable. If you press the fingerprint on the jelly, you can get an opposite fingerprint, and then press it repeatedly with two pieces of soft candy, it seems that you can actually copy a fingerprint.

But the problem is that the texture on a piece of jelly is very unclear, and the second copy estimate is difficult to fool the fingerprint machine.

The same is true, so fake fingerprints are not reliable. But it also shows that copying fingerprints is not impossible, and students with big brains will get it done.

“Gummy candy is not reliable, but the gel is ok.” Jiuji smiled.

A gel is a component of soft candy.

“You… are you whimsical?” The legend shook his head without trust.

“I used to successfully make a fake finger that can fool the fingerprint machine with a gel. Although the success rate can’t reach 100%, it has reached 70%.” Nine thousand monks said: “I only need to make three fake fingers. , you can be sure that one can be successful.”

The legend shook his head: “Impossible… it is impossible, it is just your theory!”

Gu Yuya was also very surprised: “Nine Uncle, what do you say about this?”

“Use forensic methods to extract fingerprints, then take them with a high-resolution camera, transfer them to a computer for various treatments such as left and right and reverse, and then make a fake finger.” This is not a story. I have done it, so I am familiar with it: “The accuracy of the template directly affects the fidelity of the fingerprint. Using a similar method of the printed circuit board, the sample can have subtle protrusions to meet the requirements of the mold. Finally, the gel It’s ok on the template.”

Lin Ge exclaimed: “You can’t do this, is this too great?”

“Of course, this method can’t deal with fingerprint readers that can identify transparency, softness, charge carrying, and bubble levels.” Nine thousand monks said: “So I added some crafts on this, I can make this. A good gel perfectly covers your fingers, even those that recognize transparency, softness, charge carrying and drum level can be overshadowed.”

Lin Ge admire the thumbs up.

Xu Yun is also very amazed, this level is probably only the first person he can do.

It’s not a good thing to copy this thing. In the morning and evening, this thing will be popular in this world. If you master this technology, you can easily copy the fingerprints. Everyone should wear gloves when they go out.

Once the leaked fingerprint information is used by criminals, it will bring great harm to individuals and society. The peculiarity and uniqueness of fingerprints make it an extremely important personal information, also known as personal privacy.

If the fingerprint information is leaked or copied, the consequences will be unimaginable.

More terrifying is that fingerprint recognition has one of the biggest drawbacks compared to digital password recognition technology. Once a person’s biometrics are stolen or copied, it is difficult to change their characteristics like changing a password.

So if this thing is stolen by someone, hehe, it is not as simple as finding the ball password. The digital password is back to change and the fingerprint is changed.

The legend is a bit of a circle, and he regrets that he has not set the iris code. It is because someone told him that the iris code is not safe, saying that it is now possible to produce a fake artificial iris within 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 the information from the pattern, texture and size. Once the information is output, it can be easily repeated after one hundred to two hundred iterations. Make a fake iris.

Therefore, the legend believes in the complex and unique “fingerprint”, but did not expect a bad old man in front of it can easily copy and get their fingerprints!

I knew that he had set all kinds of biometric passwords at the beginning! In this way, the passwords of his various bank accounts and company accounts can be considered safe.

In fact, this is really the case now. Only multi-mode biometrics can solve the problem of all single-mode biometric systems.

After the fat head bought what it needed, the nine thousand repairs no longer delay the time, and immediately began to work! This is a very time-consuming manual job.
