Taking pictures will leak fingerprint information on the hot search than scissorhands, and what othe

Recently, a network security expert came out to speak, and our favorite way to take pictures with scissor hands has been on the hot search for fingerprint unlocking security that will endanger our mobile phone, which is also a very sad thing. Now even taking a photo and posing for what kind of pose you have to be controlled by information security, you say sad is not sad.

We all know that now our information leakage problem is very serious, and the fact that the mobile phone payment was swept away before was swept away by someone who took advantage of the loophole to sweep away the money was also panicked.

This time, it broke out that the ** within meters of scissor hands can basically restore fingerprints 100%, and only those that exceed three meters are difficult to extract fingerprint information. When I heard the news, I didn't know whether to be happy or sad about the development of science and technology. The development of science and technology is an excellent thing, but I am afraid that someone will use it to do bad things.

Than scissorhands will leak fingerprints incident tells us that fingerprint unlocking methods are not as secure as we used to think, that exceptThe fingerprint unlocking method has security risksIn addition, what other unlocking methods are also risky?

I think the most unsafe unlocking method is our previous sliding unlocking method, which is really not technical or safe. It can be said that as long as someone else gets our mobile phone, the unlocking operation can be completed without any difficulty. So,The sliding unlocking method has the highest risk factor, but there should be very few people who use swipe to unlock it now.

The second highest risk coefficient should be the pattern unlocking method that many of us often use, the main disadvantage of this method is that it is easier to be remembered to unlock the pattern, and this unlocking track can also be guessed by the scratches we leave on the mobile phone screen, so it is saidThe risk factor of pattern unlocking is still relatively large

The above three unlocking methods have their own dangers, in comparison, the traditional password unlocking security factor is still relatively high, but don't set it too simple, and set the password, you must remember it very clearly, you must pay attention to protect your information security!

In addition to fingerprint unlocking, I think the most dangerous thing is, of course, face unlocking.

In fact, any unlocking method is risky, and any program has vulnerabilities.

There are also certain risks associated with unlocking methods such as brushing your face and shaking your head.

The unlocking method of general face recognition is also dangerous, because many people like to post ** in the circle of friends.

I think the danger factor of sliding unlocking and pattern unlocking is also quite high.

I think the current unlocking method is particularly risky, and it should be facial unlocking.

Face unlock, face unlock is also a risk, pay attention to protect your privacy.

Face unlocking is also a risky way, and it is also necessary to pay attention to it.

Than scissor hands leak fingerprints is pure Internet rumors, through the technology of obtaining fingerprints can only be said to be theoretically feasible and more difficult to use in practice, not only to ensure that the camera has a very high resolution, the fingertips on the fingers should be clearly exposed, the distance of taking pictures should not be too far, if the shooting distance is greater than 100cm, it is easy to cause **fingerprint blur, it is difficult to extract correct information.

Generally in scenic spots or friends when taking photos than scissorhands, the former must be shot at a distance, the latter shooting is generally carried out with a mobile phone, and the mobile phone has a filter beautification function, it is difficult for someone to release ** without the processing and modification of the beautification software, **The whole person on the ** may not match the reality, not to mention the fingerprints.

The second is the esoteric extraction of fingerprint technology, the right time and place and the indispensable people, the amount of money is higher, this unbalanced way of income and expenditure is often not used by ordinary thieves, if you are worried that there are criminals will extract your personal information through**, you can solve the problem from the root, in all fairness, now taking pictures of scissor hands is a more outdated behavior, when taking pictures, you can refer to the fashion hard photos of international supermodels, through different postures and gestures to shoot a tall **, will make others and themselves pleasing to the eye, It also puts an end to the opportunity for bad guys.

In recent years, there are more and more forms of mobile phone payment, major banks, Alipay, WeChat, etc. have opened the fingerprint payment function, reducing the time we enter the password every time we pay, but we do not rely on fingerprints and cardless payment, the choice of fingerprint can be used with the thumb or little finger, not the fingerprint of the middle finger and index finger, and more change should be prepared on weekdays in case of emergency.

Taking pictures than "scissorhands" does have the possibility of leaking fingerprint information, but it is also affected by factors such as the clarity of the photo and whether the upload** is compressed, and only when the hand is close enough to the camera, the camera resolution is high enough, and the upload is the original**, it is possible to leak fingerprints.

Some experts remind the public that it is easy to leak identity information when taking pictures than the scissor hands, basically the scissor hands taken within the meter can restore 100% of the fingerprints of the subject, and the ** shot at a distance of meters -3 meters can restore 50% of the fingerprints, and only more than 3 meters of shooting ** is difficult to extract the fingerprints.

It's less scary than scissorhands leaking fingerprintsDoes taking a picture better than scissorhands really give away fingerprints? It's not that simple.

Among the major biological characteristics of people, fingerprint is one of them, and the others are more familiar to us, such as DNA, facial features, iris, etc. An important feature of a person's fingerprint is that it does not change with age. Of course, each person's fingerprint is also unique, otherwise, it cannot be used as identification.

However, if you want to extract the local details of fingerprints, the conditions will be very harsh, and it is generally difficult to achieve these theoretically required conditions

Moreover, if the fingerprint leak is used to crack the mobile phone or fingerprint password lock, after the criminals obtain your fingerprint information, they must also have access to your mobile phone and password lock, which needs to meet another condition in order to achieve real cracking.

Why did this news attract so much attention? A big reason for this is that when it comes to security, it's easy to over-interpret it.

However, saying that scissorhands are easy to leak fingerprint privacy can indeed raise our vigilance. As our lives become more and more intelligent, there will be more and more application scenarios of biometrics, and protecting biometric features is to protect personal privacy. Once online, it is completely uncontrollable for the individual.

If an individual is harmed because of this, it is too late to regret it.

In order to protect yourself, you need to strictly adhere to the first level, biometrics should not be easily disclosed. This may not be completely guaranteed, but the first thing to do is to establish this sense of self-protection and establish the first firewall.

Finally, biometric recognition is a technology that is worth using, and we can't give it up because of concerns about security.

Whether it is fingerprint recognition or face recognition, in the vast majority of cases, it is still very secure. It provides convenience while maintaining safety.

Safety is a system, first of all, people have a sense of self-protectionIn addition to multiple security technologies, network service providers are also required to do a good job of protecting personal privacy and ensuring the security of personal identity. As long as these aspects are synergistically linked, biometrics can still be trusted.

Than scissorhands to take pictures will leak fingerprint information?

A few days ago, I watched TV and said yes, now the mobile phone, the camera takes pictures with a very high definition, and the fingerprint restoration of the photo scissor hand within 3 meters can reach more than 90.

Sometimes it's like the whole world is full of spies, we are all ordinary people, don't think too much.

Possibly, because technology is too high these days.

No, otherwise, those leaders will also wave hello on TV.

No, the beauty is so beautiful that I don't know my mother, and I can still see my fingerprints?

Posing scissor hands when taking pictures will reveal our fingerprints, and of course this leakage is also conditional. As for how we can protect our own information security, I think we can try to enter our fingerprints on unfamiliar devices as little as possible, try not to go to irregular Internet cafes to surf the Internet, do not fill in information about ourselves, etc., these can effectively protect our information security, as long as we pay more attention in our daily life. <>

In today's era of very advanced technology, our information is always facing the risk of being leaked, after all, today's era is an information age, and when others get our personal information, it is possible to use our information to do some bad things. It is said that the pose of scissor hands will reveal our fingerprints, of course, this leakage is also conditional, and this condition is the distance to take pictures. If the photo distance is more than three meters, then you can rest assured that this scissor hand will not reveal our fingerprints, but if it is within three meters, there is a very high possibility, especially if the photo distance is within one and a half meters, then this will definitely leak our fingerprints.

As for how to protect our information security, first of all, when we take pictures, we should try not to pose with scissor hands, if we want to pose, then the distance from this photo must be three meters away. We also need to make sure that it is not safe to register on the Internet**, especially if you need to enter your ID number. In life, we also try not to listen to the words of the street salesman and fill in our own information because of a little profit.

There are many ways to protect your information, but the most important thing is that we don't casually tell others about our ID card information, password, etc. The most effective way is to have more dim sum eyes.

When taking pictures, you need to look at the pixels of the camera and add or not to add filters than whether the scissor hands can leak fingerprints, and generally will not leak fingerprints, if you are afraid of leaking, you can blur the fingerprints after taking a good shot.

Scissorhands do not reveal their fingerprints when taking pictures, and only when pressed in one place will they leave traces, and the pixels of the general camera are not up to the level of being able to see fingerprints.

Fake. The general photography technology cannot reach the accuracy of accurately identifying fingerprints, and there is a high probability that it will be compressed to cause further distortion when it is sent to the Internet, so that fingerprints cannot be identified.

Fake. Fingerprints need to be rubbed with professional tools, and only one ** will not be leaked.

Theoretically, when the clarity reaches a certain level, you can see the subtle lines, and with the current technology, it is still relatively difficult, so you can take pictures with confidence.

If it is relatively close to the lens and there is enough light, it is possible, but if it is far away, it is unlikely.

Everyone is familiar with scissorhands, and we often encounter this pose when we take pictures。But I read a report some time ago. Experts point out that it is easy to leak one's fingerprints when holding out a scissor hand while taking pictures.

I was really shocked and scared to see this news, because I used to use scissor hands when I used to take pictures.

Using scissor hands when taking photos can reveal one's habits. Let's take an analogy, if a left-handed person is comparing scissorhands, will he necessarily use his left hand? Then it will be observed by others.

In fact, under normal circumstances, no one would be so idle, unless it is some people with bad thoughts. Either way, we still have to pay more attention. Avoid some criminals taking advantage of the loopholes.

Take a photo with scissor hands, and there is a good chance that the fingerprints will be restored one-to-one。If the distance between your finger and the camera device is meters, then your fingerprint will be 100% copied. If the distance is within three meters, it may be copied by about 50%.

Therefore, if we take pictures in the future, we must be three meters away, which is a relatively safe range. Everyone's fingerprints are different and all are unique. If it is really leaked, it is indeed more dangerous.

In fact, there are still some safety hazards in life。For example, WeChat, which we often play, will post some of our own ** or family members' ** in the circle of friends. If there are some strangers in your WeChat friends, they may import ** when they see it, then it is difficult to estimate where this ** will spread.

Therefore, everyone must be cautious and cautious when using online platforms.

It may reveal the appearance and allow criminals to take advantage of it.

If the photo is leaked, it may lead to theft by criminals.

It's just a license, and there is not so much harm.

And the avatar will also be stolen and used to do some improper things.

It is possible to take a screenshot of your profile picture to scam your family.

It may also be scammed by others who steal their profile picture information.

There are still many harms, and if scissorhands can leak fingerprints, it is really a ubiquitous hazard.

In addition to revealing fingerprints, it is likely to reveal some of your lifestyle habits.

According to Echizen Gong, a professor at Japan's National Institute of Informatics, pointed out in a recent interview with ** that if the light is bright when taking a picture and the focus happens to be on the fingerprint, the fingerprint information can be restored through **. If you create an artificial finger from this, you can pretend to be the person who registers various fingerprint recognition terminals, so be careful when taking photos with "scissor hands".

In 1941, Winston Churchill, then British Prime Minister, used the "scissorhands" symbolizing victory for the first time in a speech to express his determination to win. Since then, "scissorhands" has spread among people. In life, it has long been commonplace to be a "scissorhands" and shout "yes" when taking pictures.

According to reports, Echizen Gong used ** in the experiment was taken by a commercially available 20.4 million pixel digital camera, and fingerprint data was obtained after image processing of the **. Fingerprints can be clearly displayed at a distance of 3 meters. Therefore, Echizen Gong said that there is a possibility of stolen fingerprints taken at a distance of 3 meters, and "the technical threshold is not high, and anyone can easily deal with it", and at the same time, "with the development of technology, the camera focusing function is becoming more and more powerful, and it is possible to know who has what kind of fingerprints through the sharing of ** in the future."

> fingerprint information is widely used in various identification and authentication as part of personal biometric information, and its core point is to collect clear fingerprint information for the generation of feature points. Only ** that can extract accurate feature points will leak fingerprint information. In fact, it is not enough to collect enough data based on ordinary landscape photos and existing camera pixels.

That is to say, only during the shooting**, the finger texture is clearly visible, and the fingerprint information will be leaked. At present, it is difficult to shoot the texture of the finger clearly within the range of the normal shooting distance (greater than 1 meter). Normal fingerprint collection must be collected at a very close distance, in a strictly limited direction and under a specific light brightness.

At the same time, the current network transmission will compress the **, thereby reducing the clarity of the **, resulting in the loss of **details, and the possibility of leaking fingerprint information is relatively low. ”
