What are the advantages of iris recognition and fingerprint recognition?

Iris scanning is mainly used for identification by scanning a person's eyes. Traditional iris scanning requires the use of specialized instruments, and iris recognition requires four steps, divided into iris image acquisition, image pre-processing, feature extraction, and feature matching. Whether iris recognition will replace the popular weighing fingerprint recognition is a matter of the advantages and disadvantages of these two identification methods.

 

  First of all, iris recognition has an advantage in terms of security. The iris is an integral part of our eye, and it remains unchanged throughout its life course after the fetal development stage. Like fingerprints, each person's iris is unique. The main advantage of iris recognition over fingerprint recognition is that it leaves no physical imprint and is less likely to be stolen. In addition, since iris recognition can only detect information in vivo, it is impossible to fool people with photos or videos, so security is guaranteed.

 

  Secondly, in terms of convenience of use, fingerprint recognition is superior to this. This is something we know when we look at the process of iris recognition. First, you need to pick up the phone, light up the screen, then move your eyes to the recognition frame of the front camera and wait for the recognition to complete. The process is more tedious than fingerprint recognition. Whether using rear or front fingerprint recognition, when picking up the phone, it can already be recognized and unlocked.

 

 

  The last is in the use of the scope; for the time being, fingerprint recognition has the advantage. The Galaxy Note7's iris recognition is only used for screen unlocking and verifying Samsung accounts, so the current range of use is not large. Compared to the already highly mature field of fingerprint recognition, iris scanning is just in its infancy and will take some time to improve. In addition, users are already accustomed to using fingerprint recognition, so it is still unknown whether iris recognition can replace fingerprint recognition in the future.
