What do you think about the current security problem of fingerprint mobile phones?

I think it's safer to prevent children from playing with mobile phones, at least he can't open it without your permission.

In fact, I don't think it's that An is not safe, but that it's too convenient, so everyone will use it like this.

Fingerprints are not secure, they can only be said to be convenient, and now the most convenient way is still a password.

The fingerprint mobile phone does not necessarily use the function of the fingerprint often, because these functions are hurtful to the eyes and the gains outweigh the losses, so few people like to do this, and the electroplating film of the fingerprint is very easy to use to defraud.

I think the fingerprint password is still relatively safe now, because the fingerprint chip technology is now very passable.

Fingerprints can indeed make the phone a little more secure, but I don't think it's safe enough, because fingerprint fraud is not very difficult.

Personally, I feel that the fingerprint mobile phone is just an application of biotechnology, and it can still be rolled and pointed.

I think that the security of fingerprint mobile phones is actually more difficult to prevent. It is said that orange peel has the same texture as a human finger and can be stolen.

Like WeChat, the practice of uploading the fingerprint of fingerprint payment to Tencent cloud is very insecure, and I hate Tencent's practice, which is shameful. Once a single cloud is attacked, the information will be leaked, and the fingerprint information should be stored locally on the mobile phone.

The vast majority of today's fingerprint phones are very secure, and there may be a very small number of vulnerabilities, which is very rare, so we don't have to worry about this kind of problem.

Fingerprint mobile phones can be used conveniently and quickly, but if the accuracy is not high, it will cause a lot of trouble, so the accuracy and security should be continuously improved.

To a certain extent, it is relatively safe, but there are also many drawbacks, and the details are not taken into account.

1. Fingerprints are protruding lines on the epidermis. Although fingerprints are available to everyone, they are different, and fingerprint recognition is a kind of biometrics, which is a very safe and convenient way to identify;

2. Although fingerprints may be copied, they are safe enough for mobile phones, and if biometrics are used for bank cards and other higher security levels in the future, technologies such as iris recognition can be used to prevent copying;

3. The mobile phone fingerprint is enough for the protection of ordinary users' mobile phones, if you want higher protection, you can use face recognition or iris recognition.

Try installing a security software (e.g. Phone Manager, etc.). Take Phone Manager as an example, open Phone Manager, click on the main interface of the one-click physical examination to automatically detect the problems in the phone, and give treatment suggestions, click one-click to remove the virus program.

If you restart your phone and find that the virus still exists or prompts that it cannot be deleted, please obtain root permission first and then perform in-depth scanning, and you can use the one-click root tool on the computer to obtain root.

You can also try to use a special virus killing tool for one-click scanning, and if you find a problem with your phone, please deal with it as soon as possible to prevent property loss.

Personally, I think fingerprint unlocking is still relatively safe... Even if the virus copies your fingerprint, cloning your fingerprint is not a simple task, and ordinary people can't do it, so you can use it with confidence.

Mobile phone fingerprint recognition is not a perfect fingerprint recognition that is lifelong, unique and convenient. It is also impacted by individual artificial fingerprints now.

The success rate of unlocking a smartphone using an artificially created "fake fingerprint" is as high as 65%. Fingerprint recognition is facing a security crisis. The machine collects the user's fingerprint information through the fingerprint sensor, and stores the complete fingerprint information in the fingerprint flash.

Because the fingerprint information is not encrypted by hardware at this time, it is easy to be cracked, resulting in the leakage of the user's fingerprint information.

In response to these weaknesses, mobile phone manufacturers have begun to use more methods to protect fingerprints, such as hardware encryption and storage of key information of fingerprints, in addition to fingerprint verification, but also use fingerprints, blood and heart rate signals to verify user fingerprint information together to improve security.

Security is always relative.

1 Gionee M6S Plus fingerprint + blood flow + heart rate detection.

Configuration: Powered by Snapdragon 653 processor.

Identification: fingerprint recognition + liveness detection + encryption chip.

2 Samsung Galaxy S8 S8+ Fingerprint + Face + Iris Detection.

Spec: Powered by Snapdragon 835 Exynos 8895 processor.

Recognition: Fingerprint Recognition + Facial Recognition + Iris Recognition.

3 Huawei Mate 9 3D fingerprint + financial-grade chip.

Configuration: Qualcomm Snapdragon 653 processor.

Identification: 3D fingerprint recognition + financial-grade chip encryption.

In the future, mobile phone fingerprint design will be the same as other aspects of technology, there will be new developments. The ability to defend will definitely be improved even more.

With the development of the times, mobile phones have become an inseparable part of our lives, and now it has become the era of fingerprints. But some people say that fingerprints are not safe. In fact, it is relatively safe because the fingerprint is unique.

The local characteristics between these two fingerprints are often similar, so fingerprint-based security systems in mobile phones or other devices are much more fragile than expected. As fingerprint sensors become smaller and smaller, it is necessary to increase the resolution of the sensor to capture more features. If the resolution is not increased, it will inevitably compromise the uniqueness of the user's fingerprint.

This is also confirmed by empirical analysis. ”

This includes the need to develop effective technologies to prevent counterfeiting; Users carefully choose the number and type of fingerprints when registering; Instead, out of 800 complete test samples, the researchers found only a complete artificial fingerprint that could be used as a super fingerprint. "Not surprisingly, partial fingerprint matching has a better success rate than full fingerprint matching, but most devices are used to match partial fingerprints.

The researchers analyzed the characteristics of the "super fingerprint" in the real fingerprint image and established an algorithm for synthesizing the "super fingerprint". Experiments have shown that synthetic fingerprints are easier to match than real fingerprints, and it is easier to deceive security identification systems. The "super fingerprint", which consists of real fingerprints, successfully matches 26 -65 of the user's fingerprints in the system.

The success rate depends on how many fingerprint images the user has stored and is set up to a maximum of 5 attempts at a time.

The researchers believe that this research will influence the direction of the future design of security systems. At the same time, the note also states that:It is still safe to unlock your phone with a passcode.

Is fingerprint unlocking for phone really safe? It's not too late to know now, so remind your family as soon as possible.

The area of the mobile phone fingerprint recognition sensor is limited, and all the information of the fingerprint cannot be entered, and a foreign study has found that it is precisely because of this vulnerability that some people's fingerprints will be unlocked by others. Some mobile phones support 5 fingerprints, and the more fingerprints entered, the greater the chance of being unlocked by others, so fingerprint recognition is not absolutely safe.
