What is Iris Recognition in Access Control ?

Iris Recognition is a method of biometric authentication that uses pattern-recognition techniques based on high-resolution images of the irrides of an individual's eyes.

Iris recognition has been the most authentic and reliable security device used in access control security system. Iris scanner is used for physical security as it inspects far better than other iris recognition devices. Iris scanner will take a digital photo of the iris of a person which cannot be altered or manipulated with ease. The access control iris scanner will take the photograph of the iris of a person using infra red rays which are less or no harmful to the most sensitive organ of a human body. Once the digital photograph is taken,the iris scanner compares it with the recorded iris proof of a particular person to grant access.

Iris Scanner and Recognition

The human iris is a thin circular structure in the eyes which is responsible for controlling the diameter and size of the pupils. It also controls the amount of light which is allowed through to retinal in order to protect the eye's retina. Iris color is also a variable different to each person depending upon their genes. Iris color will decide eye color for each individual. There are several colors for iris such as: brown (most popular color for the iris), green, blue, grey, hazel (the combination of brown, green and gold), violet, pink (in really rare cases). The iris also has its own patterns from eye to eye and person to person, this will make up to uniqueness for each individual.

Iris recognition systems will scan the iris in different ways. It will analyze over 200 points of the iris including: rings, furrows, freckles, the corona and others characteristics. After recording data from each individual, it will save the information in a database for future use in comparing it every time a user want to access to the system.

Iris recognition security systems are considered as one of the most accurate security system nowadays. It is unique and easy to identify a user. Even though the system requires installation equipment and expensive fees, it is still the easiest and fastest method to identify a user.

Advantages of Access Control Iris Scanner

• Iris scanner is much faster in doing the iris identification process than other iris recognition devices.
• Iris scanners are capable of recognition more than a million different subjects and can produce results without confusion.
• Iris scanner can not only be used as a recognition or attendance device in access control but they can also be used as locking system.
• The imaging process of iris scanner involves no harmful infra red rays or laser lights that will affect the subjected part.
• Iris recognition devices in access control system are also available with voice support which is an added advantage.
• It is easy to search through the access log of the device anytime and acquire the data.
• Iris scanners consume very less electricity thus they are pocket friendly too.
• Iris recognition device of access control system can be used in severe weather conditions too.
