Iris scanner how does it work




















Contactless — whilst proximity to the iris scanner is necessary, Iris Recognition provides a contactless solution which makes it hygienic to use and less intrusive to the end user. Flexible and Scalable — Iris recognition is extremely flexible. The use of an infrared camera means scanners can be used at night or in the dark. Because of its flexibility, Iris Recognition is also highly scalable and has been deployed by government and other agencies worldwide.

The technology in the iris scanner detects movement of the iris which identifies the liveness of the individual, reducing the risk of forged access through high quality static images. Fast Matching — if an individual is already enrolled in the biometric system, Iris Recognition is one of the fastest forms of biometric identification.

Five Disadvantages of Iris Recognition Whilst the benefits of Iris Recognition are numerous, there are potential issues to be considered, some of which relate to the technology or to the way the technology is deployed.

Things to consider include: Distance — whilst we have discussed the merits of contactless technology, there is still a maximum distance a person can stand from an iris scanner which may be challenging in certain environments Movement — to accurately scan the iris, the technology relies on the subject remaining as still as possible.

If a handheld scanner is being used, it also relies on the operator having a steady hand, otherwise, iris scanning may be tricky. Memory — computer memory is required for the data storage; however, this is becoming less of an issue as we move towards cloud-based storage solutions. Reflection — placement of the scanner is important to the elimination of reflections due to contact lenses and eyeglasses.

Cost — due to their high levels of accuracy, iris scanners may be more expensive than other forms of biometric hardware. Fingerprint Recognition and Facial Recognition may represent provide more cost-effective solutions in some circumstances. NEC and the future of Iris Recognition There are many companies out there who provide Iris Recognition as a biometric authentication solution. How can the Internet of Things IoT help businesses?

Mar 12, In a word, yes. Iris recognition is different from retinal scanning in that it measures only the surface appearance of the eye.

An iris scanner is just a high-resolution digital camera coupled to some sophisticated image-processing software that distinguishes the coloured part of the eye from eyelids, eyelashes and pupil, and compensates for environmental factors.
