Is fingerprint recognition safe? Disadvantages of fingerprinting

Safety, everyone's fingerprints are different.

The disadvantages of fingerprint recognition are as follows:1. The fingerprints of some people or groups are difficult to image because of the few fingerprint features.

2. In the past, because of the use of fingerprints in criminal records, some people were afraid to "record fingerprints". However, in fact, the current fingerprint identification technology can ensure that no data containing fingerprint images is stored, but only encrypted fingerprint feature data obtained from fingerprints.

3. Every time the fingerprint is used, the user's fingerprint imprint will be left on the fingerprint collection head, and these fingerprint traces have the possibility of being used to copy the fingerprint.

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.

Does it support fingerprint recognition? ——Analyze the current situation and trend of mobile phone unlocking methods.

With the continuous development of technology, the way to unlock mobile phones is also constantly updated. In addition to the traditional password and pattern unlocking methods, more and more mobile phone brands have begun to support fingerprint recognition unlocking. Then, whether it supports fingerprint recognition has become an important consideration for consumers when buying mobile phones.

This article will analyze the current situation and trend of mobile phone unlocking methods to answer the question of whether fingerprint recognition is supported.

At present, most of the mobile phones on the market support multiple unlocking methods. Among them, combination locks and pattern locks are the two most traditional and secure unlocking methods. However, combination locks and pattern locks are not used frequently, and many users find these two methods too cumbersome.

Therefore, more and more users are starting to choose fingerprint recognition unlocking. This unlocking method is not only fast and convenient, but also relatively safe, and is widely used by users.

In recent years, mobile phone manufacturers have also begun to support fingerprint recognition and unlocking methods on a large scale. Apple was the first to introduce fingerprint recognition technology, and applied it to the fingerprint recognition unlock function when it launched the iPhone 5S. Since then, more mobile phone manufacturers have also chosen to add fingerprint recognition functions to ** mobile phones, such as Samsung, Huawei, OPPO, etc.

With the continuous popularization and upgrading of fingerprint recognition technology, more and more brands have begun to pay attention to the security and reliability of fingerprint recognition, and continue to innovate.

Although the fingerprint recognition wheel is convenient and quick to unlock the lead letter, it is not foolproof. Because fingerprint information can be stolen and maliciously exploited, it can pose a serious security risk once hacked. To this end, some mobile phone manufacturers have begun to increase the security management of fingerprint recognition, such as strengthening the encryption of fingerprint data and improving the confidentiality of fingerprint recognition.

In general, although there are more and more mobile phone brands that support fingerprint recognition unlocking, not everyone chooses to use fingerprint recognition unlocking. After all, everyone's requirements for unlocking methods are different. Some people are more security-conscious and therefore prefer to use a password or pattern to unlock, while others focus on speed and convenience and prefer fingerprint recognition to unlock.
