Iris Scan
Retinal scans are considered to be the most secure forms of biometric security.
Biometrics is defined as using physiological characteristics of an individual for identification purposes. There are many forms of biometric identification including: fingerprint, finger vein, palm vein, iris recognition, retinal scans, facial recognition, voice recognition, hand geometry and others. Fingerprint biometric identification is by far the most popular modality and it uses a person's fingerprint (regardless of which one) as the basis for identification in a biometric authentication system. However, since a certain percentage of the population has unidentifiable fingerprints due to age, degradation or cuts, bruises or scrapes, it is not considered the most reliable form of biometric identification. It is usually, however, the least expensive.

Biometric access control is access control where the identification process is made through biometric parameters. Some other researchers refer to it as the identification of humans by their characteristics or traits.
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.

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
