The「iris」is 「the donut shaped membrane 」in the eye.
The iris consists of the muscle which adjust the opening of the pupil, and has the function to adjust 「the amount of light」coming into the inside of the eyeball from outside. Normally 「color of eyes」means this「color of iris」.
Why can the iris identify the person?
「The iris pattern」differs each other like the fingerprint and is not duplicated.
The iris has pattern and that「iris pattern」differs by each person like a fingerprint. Although the iris is a part of body, there is almost no genetic influence, and it differs in the same person and the identical twins.
Also the iris, differing from face, fingerprint, has a big feature that it will 「not aging change 」in the rest of life from about 2 years after birth.
Who first presumed the Iris Recognition?
It's Professor John Daugman at Cambridge University.
The ophthalmologists in US Leonard Flom and Aran Safire discovered 「the iris pattern differs by each other」in 1986, and applied for a patent (Flom patent).
Furthermore, Professor John Daugman at Cambridge University applied 「the patent of coding an iris pattern based on mathematical grounds (Daugman patent)」in 1992.
Can the Iris Recognition be used for the eyes with contact lens・colored contact lens?
There is no problem for general and uncolored clear contact lens.
For colored contact lens, it cannot be used because the pattern of the colored lens covers the iris pattern and bothers the recognition.
Can the Iris Recognition be used for the eyes with glasses?
It can recognize with glasses and transparent goggles. However, to capture the image of iris the infrared light is irradiated and in case of wearing glasses an recognition error (false rejection) may occur depending on the place of the reflection of the infrared light on the glasses.
Can the Iris Recognition be used for the eyes with sun glasses?
If the sun glasses are permeable enough the infrared LED, it can recognize.
To capture the image of iris, the infrared light is irradiated and it depends on the permeability of the light of the sun glasses.
According to our SDK test, there are some successful cases of the eyes as imaging object are visible by sight through the sun glasses. More details can be checked by the development license.
Is the camera for the Iris Recognition a normal camera?
In general, a specific camera for photographing the iris is required.
For photographing the iris, it requires to irradiate the infrared light, and a normal visible light camera can not be used because it is embedded with the IR cut filter for better image.
Is it possible to recognize at outside (under sunlight)?
There are some cases of recognition errors because of the photographing places and sunlight reflection, so we recommend to test in similar environment before the formal introduction. It is expected to increase the accuracy by our iris composition technology.
Is it possible to recognize at dark place?
The infrared camera is used for photographing the iris and it is doable at dark places. When in dark places the pupil diameter gets larger but by utilizing Panasonic patent technology a recognition error due to the change of the pupil diameter hardly occur in the specification.
Is possible with bloodshot eyes by the conjunctivitis?
There is not problem with the conjunctivitis and bloodshot eyes because they do not influence to the iris.
The eyes are constituted with the sclera as the white part, the pupil as the central black part, and the iris as the donut shaped part in between them. The conjunctivitis and bloodshot eyes make the sclera red, and if they do not influence the iris pattern then there is no problem on the recognition.
Does the iris change by aging?
The iris will not aging change after 2 years of the birth.
The human iris pattern is immobilized by approx. 2 years after the birth, and there will be no change in rest of life.
However, There is a case of iris change due to a surgery and, injury which influences the iris area and loss of iris pattern.
Does the Iris Recognition need both eyes?
One eye is still possible.
One eye is still possible, and both eyes are possible without doubt.
It is possible to select how to use based on service type and usability.
Are the iris of right and left eyes same?
No, they are different.
The iris of a person is differ between right and left eyes.
Are the iris of twins (identical twins) same?
No, they are different.
The iris rarely get the hereditary influence, so the iris patterns of identical twins who have same DNA are different.
The fingerprint as well as the iris is different between the identical twins, but it was clarified by the research that the iris is more complicated than the fingerprint.
Is it possible for a dead person?
The recognition of the iris is not possible because when a person died the iris muscles relax and the pupil expand.
The iris is a tissue made of the iris muscles, and when a person died whole body muscles get relax as well as the iris muscles, and at the end the pupil stayed open.
With these reasons, the Iris Recognition for a dead person is not possible.
What is the difference between the Iris Recognition and the face authentication?
Things to use for recognition and the presence of aging change are different.
The face authentication uses 「face features (the frame of the face, the positions of parts like eyes, nose)」to recognize person, and the Iris Recognition uses 「the iris in the eyes」. The Iris Recognition needs only the iris information and not influenced by 「the presence of the mask and mustache」. It is still possible to recognize a Muslim woman wearing 「Hijab」as far as her eyes are exposed.
Also the face relatively is easy to get aging change, but the iris is not.
Is it possible to recognize eyes took LASIK operation?
The LASIK operation is the surgery of the cornea and it has no influence to the iris pattern, so it's still possible to recognize.
Can the person who has visual defects, cataract・glaucoma use the Iris Recognition?
It depends on the condition of the symptom.
The presence of influence to the iris pattern is the point of propriety.
Does not the infrared LED bring a bad influence to the eyes?
The iris camera is required to meet the IEC62471 safety standard.
In case of having continuously high light quantity of the infrared rays for long time, there may have influence to the eyes.
To avoid such situation, it is required to produce the iris camera to meet the photobiological safety standard IEC62471.

How much are the price・fee of the Iris Recognition system
We are ready to provide the estimation of it separately.
The license of development is \600,000(tax excluded) . For the commercial use, it depends on the system structure and the contribution degree of the Iris Recognition engine. The contract of revenue share is also available.
Is there any risk of leaking the iris photograph data?
After coding the iris image, it is possible to restrict the leak by destructing the iris image.
After photographing, the iris image is converted to the iris code and right after that the iris image can be destruct, so this can restrict the leak of the iris image. The Iris Recognition will use only the iris code and there is no need to save the iris image.
What are the merits・demerits of the Iris Recognition?
Merits: Convenient・High accuracy・No aging change / Demerits: Expensive・Only few installation examples
One of the merits of the Iris Recognition is no need of carrying and remembering anything due to recognize a person by using a part of the body which differs from [the possession authentication」using a key・IC card and 「the intellectual authentication」using ID・password.
And other merits comparing to other biometrics authentications are the touchless, no aging change.
Some demerits are less company of developing it in the world, not familiar yet and the price is still expensive, and less example of installation.
What is the recognition speed?
It is less than 1 second.
In the Daugman algorithm it says the recognition speed is about 1 second from providing the iris image, but our Iris Recognition enables to recognize faster than that.
Is it possible to install the Iris Recognition SDK to smartphone and tablet device・PC?
It may need a embedded adjustment depending on the design・specification of the smartphone and tablet, PC.
Is it possible to embed the Iris Recognition to a robot?
Our Iris Recognition SDK can be operated on LinuxOS / MacOS / WindowsOS. Also the operation by Raspberry Pi3(Jessie) is already confirmed, but it may not operate depending on the kind of OS. Please contact us for confirmation.
