Samsung note7 has been officially launched in China. In addition to its good-looking appearance and flagship-level configuration, the biggest highlight is undoubtedly the new iris recognition function. Samsung note7 is not the first to use the iris recognition function. For mobile phones, Lumia 950 XL has used this function as early as a few years ago, but the attention is undoubtedly not as high as the current Samsung note7.
Iris scanning mainly scans people’s eyes for identity recognition. Traditional iris scanning requires the use of specialized instruments. Iris recognition requires four steps, which are divided into iris image acquisition, image preprocessing, and feature extraction. and feature matching. Will iris recognition replace the now popular fingerprint recognition? This starts with the advantages and disadvantages of these two recognition methods.
The first is safety. Iris recognition undoubtedly has advantages. The iris is an integral part of our eyeballs. After it is formed during the fetal development stage, the entire It remains unchanged throughout life. Like fingerprints, each person's iris is unique, and compared with fingerprints, the biggest advantage is when using iris recognitionIt does not leave any physical marks and is not easy to be stolen. In addition, because iris recognition can only detect living body information, it is impossible to get through with photos and videos, so it is superior in terms of security;

The second is the convenience of use. Fingerprint recognition is superior in this aspect. As for why, you only need to look at the process of iris recognition to know. First, you need to pick up the phone and turn on the screen. Then move your eyes to the recognition frame of the front camera and wait for the recognition to be completed. It can be seen that the process is more cumbersome than fingerprint recognition. Whether it is rear or front fingerprint recognition, you can basically recognize it at the same time when you pick up the phone. and unlocked.
Finally, in terms of scope of use, fingerprint recognition has advantages for the time being. Currently, the iris recognition of Galaxy Note7 is only used for screen unlocking and verifying Samsung accounts. The current usable range is not large. Compared with already Highly mature fingerprint recognition and iris scanning are just in their infancy and will take some time to improve. Users have become accustomed to using the fingerprint recognition function. It is still unknown whether iris recognition can replace fingerprint recognition in the future.
