For a while, there was a lot of buzz on the Internet:

Taking a photo can be stolen by someone's fingerprints, log in Alipay and transfer your money?

Is this true?

If it is true, the faster technology develops, how can safety be guaranteed?Is technology development going backwards?

Let’s discuss this topic together today, and see how Alipay officially responded to the security issues rumored on the Internet.

Cybersecurity experts respond to photos leaking fingerprints

Recently, experts from industry associations said that if the lens is close enough when taking pictures, it is possible to use "scissor hand" photos to restore the pictures through photo enlargement technology and artificial intelligence enhancement technology.personfingerprint information.

Network security experts said that if the camera is taken in a "scissor-hands" posture, if the lens is too close, the person in the fingerprint information photo can be recovered through photo enlargement technology and artificial intelligence enhancement technology.

If a photo of scissors hands taken within 1.5 meters can recover 100% of the subject's fingerprints, photos taken within a distance of 1.5 meters to 3 meters will recover 50% fingerprints, and photos taken outside the illuminance meter Not worried about this.

The problem is, after the fingerprints are extracted, the fingerprint film is made of professional materials, which can be used by criminals, such as unlocking fingerprint locks and paying with fingerprints.When the news broke, it immediately sparked heated discussions on the Internet.

CCTV Finance interviewed relevant experts and gave the answer: theoretically feasible, it is difficult to threaten information security at the operational level.

Jing Jiwu, a professor at the University of Science and Technology of China: If you take pictures with scissors, better camera shots (single portraits) may be able to recover fingerprints.Current cameras can reach 1200 megapixels, which means a 1-meter-long object with a resolution of 0.25mm can recover fingerprints from multiple photos.Usually, recovery is difficult due to things like light, but more accurate cameras are easier to recover.Any method of revealing fingerprints will threaten the user's information security.If there is a fingerprint, it can be imitated to fake an identity.Can open the general fingerprint electronic lock and open the door fingerprint work.

Shooting leaked fingerprints is better than "scissors"?Alipay: Only theoretically feasible, as long as the phone is not lost.

Alipay Digital Identity Lab Manager Gao Yi:

Media reports that the camera will display fingerprint information instead of "scissor hands".In theory, but in fact, you don't have to worry too much.
First of all, at present, mobile phone fingerprint recognition is mainly based on capacitive type.Even if you get a high-definition fingerprint, it's difficult to make a simulated fingerprint of a conductive material.
Also, some cell phones have live bodies.It is almost impossible to identify detection capabilities, such as the temperature of the skin, through the fingerprint of a mobile phone.Second, the fingerprint information is stored locally on the mobile phone and can only be used on my phone.
Even if the simulated fingerprint can be made from the photo, it is useless to get the other party's mobile phone.Therefore, Alipay is safe.

Alipay's official response is safe, but still can't take it lightly

Are you still worried about whether Alipay is safe after seeing this?Are you still worried about leaking fingerprints when taking photos?

Although Alipay's official response is safe, I personally think that we should be cautious. After all, in theory, our fingerprints can be extracted, and fingerprints may threaten the security of fingerprint logins.

So everyone must not take it lightly, especially in this circle of friends where most of them are strangers, you still have to be more careful, and you must not leave your property with security risks just to take pictures.
