Biometrics are unique physical or behavioral characteristics, of an individual, which can be measured and thus compared. Various types of biometrics including fingerprints, iris recognition, voice prints (speaker verification), facial recognition, and hand geometry.

Because biometrics are bound to an individual, they can't be shared, lost, stolen or forgotten, meaning they give the highest level of security and convenience available and can be used in place of sharing personal data.

Identification is the process of determining a person’s identity by performing matches against multiple biometrics. Verification is the process of establishing the validity of a claimed identity by comparing a verification template to an enrollment template.

The Process of recognizing an individual is by acquiring an image of an iris using a camera at a distance. The difference in the contrasts of the patterns are digitally encoded using image processing technology, then it determines if an individual is the right person by making a comparison with the pre-registered code data. High accuracy in individual recognition is achieved while the data volume required for iris code is extremely small, at 512 bytes, and the time it take it takes for matching is just 1-2 seconds.

1. Iris Recognition is overwhelmingly accurate.
2. Iris Recognition is highly reliable due to its non-contact method.
3. In particular, you don't need to worry about false rejections due to changes caused by wear and tear, or levels of dryness, such as with fingerprinting.

The Iris is a tissue, which surrounds the pupil of the human eye. The unique patters of the Iris differ from person to person, and after the 1st birthday, there is extremely little change in the pattern caused by aging, so the iris has a characteristic that is difficult to counterfeit. Because of this, the differences in the patterns are so great that it is doubtful that there are any 2 people in the world who have the same patterns; the right and left eye also differ, and even twins have different patterns. Utilizing this feature enables us to achieve extremely precise individual recognition.

Retinal scan uses a laser to scan the pattern in the back of the eye, as the retina is located in the back of the eye. Irises, on the other hand, are located at the very front of the eye, so an image of it can be taken using an ordinary video camera, relieving the subject of psychological resistance.

There are various products using fingerprinting, so it is difficult to make a blanket statement, however, we think that iris recognition is 10-100 times more accurate. Also, as irises don't require contact it provides a clean image. In the case of fingerprinting, 3-5 out of 100 people fail to be recognized if they do kitchen or cleaning work.

Cataracts and Glaucoma are eye diseases, and do not present a problem to iris image acquisition, so it should not be a problem. Similar to following eye surgery, an iris may be scarred in an operation, so re-registration is needed.
