When taking a photo than Scissorhands will leak fingerprints? Experts are theoretically feasible Wha

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. ”

Does "Scissorhands" really leak personal fingerprint passwords when taking pictures?

Than scissorhands to take pictures will leak fingerprint information?

That's awesome! What is this photo distance?

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.

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.
