Iris Scan
Retinal scans are considered to be the most secure forms of biometric security.
The system you are referring to is known as iris recognition. It is a biometric technology used to identify individuals based on the unique patterns present in the iris of the eye. Iris recognition is considered one of the most accurate biometric identification methods due to the high level of detail and complexity of iris patterns.
Biometric login can have a few drawbacks. There is an assumption that a person's biometric information cannot be "faked" but biometric experts will tell you that most biometric login methods can be defeated given enough time and resources. Some biometric characteristics change change for a person due to illness or even weather conditions, resulting in an authorized user being denied access. If it is voice - a cold can alter the voice. Injuries to hands can mess up fingerprints, infections can alter iris and retina patterns. Biometric readers can also become damaged and fail to properly authenticate a user. The damage can be so subtle that it cannot be easily detected. As a result of these potential problems it is generally not a good idea to rely exclusively on biometrics for login authentication. It is better to have it as one possible method or as part of a multi-factor authentication.
The most accurate type of Biometrics is Retina Scanning. It is almost 100% accurate. Along with the Iris, you can't change the information held in the patterns in your eye. But people can wear colored contacts, which would throw off the Iris scanning process. So in conclusion, the Retina Scanning is most accurate.
It is a technology that identifies people through their eyes.

In general, biometric readers are usually quite accurate in identity verifications. However, you will need to compare different models as with any electronics to get the best one.
when a relationship is optional then the value of the modality is zero. when mandatory then the modality is one.
Low modality is a word/phrase that is more uncertain or weak. High modality is when the word is expressed more certainly and stronger. For example: Will you do this please? is low modality Do this! is high modality
