Iris authentication is one of the popular and best ways of biometric authentication when used in highly sensitive zones. Iris authentication technology is now widely accepted in many industries for authenticating legitimate users. In order to authenticate using iris authentication, users must be registered in iris scanner devices. While registering a user, iris scanner captures the image of iris patterns and stores it in the database.
Whenever a registered user attempts to access a protected device, iris scanner compares iris patterns against the one stored in the database. Once recognized successfully, it authenticates the user. Although the technology is very accurate and reliable, deploying iris authentication can sometimes be a very tedious task. Moreover, Iris authentication technology is very costly and there it mostly used in enterprise-level industries.
