What is the technology of iris recognition?
The technology of iris recognition is used to identify individuals by photographing the iris of their eye. It falls into the category of technology known as verification based on biometric biometric security. This technology has become popular in security applications because of its easy use, accuracy and security. Its most common use is to check access to high security areas.
technology works by combining computer vision, pattern recognition and optics. First, the black -and -white camcorder approaches Iris and records a sharp picture. Iris is illuminated by a low level of light to help the camera when focusing. The frame from this video is then digitized to the 512 byte file and stored in a computer database.
This image can be seen from 16 inches (40.64 cm), so no physical contact is required. The individual's identity can then be confirmed by the acquisition of its iris and compared to the database so that the technology canState the person's identity in seconds.
Goggles or contact lenses do not interfere with the technology of iris recognition. Very few surgical interventions include a change in the iris, in which case it would be necessary to register in the database. Blind people, if they have the presence of IRIS for scanning, can also be identified in this way.
Iris recognition offers the highest accuracy in identifying individuals of any available method. This is because no two irises are similar - not between identical twins or even between the left and the right eye of the same person. Cirise are also stable; Unlike other identification characteristics that may change with age, the formula of the IRIS person is fully made up of age for ten months and remains the same throughout his life. This technology is also accurate because it uses more than 240 reworking points in the iris formulaAbout the basis for the match. For comparison, fingerprints use about 60.
technology is currently used at physical access points requiring high security, such as airports, government buildings and research laboratories. Some hotels even experimented using the room key. There is a potential to replace most of the current forms of identification based on physical approach, including everything that requires a password, personal identification number (PIN) or key such as electronic transactions, access to building or igniting a car. Unlike these physical identification methods, the iris cannot be stolen, lost or forget, so the technology solves problems with control of passwords and fraud.
