Iris recognition solutions measure the unique patterns in the colored circle around your pupil to identify and authenticate the individual. Some of the best iris recognition technology are deployed in high-performance areas such as major international airports. Fast and without the need to touch an object, iris recognition is becoming a biometric mode popular also for consumers with considerations being made to incorporate scanners into smartphones and wearable technologies in the near future.
Biometric iris reader: how does it work?
Iris recognition is a method of identifying people based on unique patterns within the ring-shaped region around the pupil of the eye. The iris usually has a brown, blue, gray or greenish color with complex patterns that are visible after inspection. As a biometric reader of iris makes use of a biological characteristic, recognition is considered a form of biometric verification.
In iris recognition, the identification process is performed through one or more detailed eye images with a sophisticated, high-resolution digital camera with visible or infrared wavelengths. Then, using a specialized computer program, a corresponding database compares the iris patterns of the subject with images stored in a database. Database can compare millions of images per second with a level of accuracy comparable to conventional fingerprint readers.
Is iris reader reliable?
In order for iris recognition to provide accurate and reliable results, the subject must be within a few meters of the camera. Some control mechanisms must be implemented to ensure that the captured image is from a real person, not a high-quality photograph. Ambient lighting should not produce reflections from the cornea (the bright outer surface of the eyeball), which darken or hinder the reading of any part of the iris. The person should stand still in relation to the camera. Certain types of contact lenses and glasses can obscure the iris pattern.
Where can the iris scanner be used?
Iris recognition, such as facial recognition, is most often used for safety-related applications. Some countries have implemented iris recognition systems at airports, points of entry or exit at institutions, and government buildings. The technology has also been used to prevent unauthorized access to personal computers and mobile devices. Small and portable iris scanner devices are available for consumer use, ignoring the need for password entry, or use of digital readers. Smartphone cameras, good quality, also have iris scanners, and can also be used to release payments, passwords, log in to email accounts, social networks, and other online services.
Advantages of using an iris reader
The iris of the eye has been described as the ideal part of the human body for biometric recognition to ensure safe, efficient and fast safety operations, especially at borders, airports, and businesses.
The iris is an internal organ that is well protected against damage and wear by a transparent and extremely sensitive membrane (the cornea). This distinguishes it from fingerprints, which may be difficult to recognize after years of certain types of manual labor.
The iris has a fine texture that, like fingerprints, is randomly determined during embryonic pregnancy. Even genetically identical individuals have completely independent iris texture.
The iris diaphragm is essentially flat and its geometric configuration is only controlled by two complementary muscles, which control the pupil diameter. This makes the iris much more predictable than, for example, the face.
Disadvantages of using an iris reader
Iris scanning is a relatively new and expensive technology. The shift to this system requires training, time, and investments that many companies and institutions do not yet have. Maybe this will change with the cheaper smartphones using this technology in their cameras.
Recognition of the iris is very difficult to perform at a distance greater than a few meters. If the person being identified is not cooperating, identification may also be difficult.
As with other biometric photographic technologies, iris recognition is susceptible to poor image quality.
People who are blind, without eyes, or with any type of injury to the iris may not have iris recognition, requiring other means for identification.
Is it worth investing in an iris reader?
The iris reader is accurate and reliable: More accurate than other biometric security alternatives or otherwise. A distinctive pattern is not susceptible to theft, loss or compromise.
It is also fast and stable, as the iris pattern is formed at 10 months of age, and remains stable throughout life. The complete registration, with instruction of use, can take less than 2 minutes. Authentication takes less than 2 seconds.
Iris scanners and readers are easily expandable, scalable, and flexible. The stored data of an iris requires only 512 bytes of storage per iris, and even large databases do not compromise search speed or impair performance accuracy. It works in stand-alone mode and easily integrates into existing security systems.
