In today’s information technology world, security for systems is becoming more and more important. The number of systems that have been compromised is ever increasing and authentication plays a major role as a first line of defence against intruders. The three main types of authentication are something you know (such as a password), something you have (such as a card or token), and something you are (biometric). The pressures on today’s system administrators to have secure systems are ever increasing. One area where security can be improved is in authentication. Iris recognition, a biometric, provides one of the most secure methods of authentication and identification thanks to the unique characteristics of the iris. Once the image of the iris has been captured using a standard camera, the authentication process, involving comparing the current subject’s iris with the stored version, is one of the most accurate with very low false acceptance and rejection rates. This makes the technology very useful in areas such as information security, physical access security, ATMs and airport security. In this project we implement iris recognition technique based on SVM(support vector machine) classifier to recognize the static images with database images to use this application in security purposes.
