Information and computer security - Assignment Examplee biometric drug user authentication system whereby the system is able to undertake automated authentication of users based on the biometric traits of their iris. The system particularly combines with use of cryptographic keys with the typical biometric traits of iris to develop authentication algorithms that can be used to provide individuals with access permission to an information system or data. As opposed to the use of the tralatitious passwords and PINs, crypto-biometric systems much(prenominal) as the iris based cryptographic keys are significantly more stable and less susceptible to attacks. For example, the public key infrastructure (PKI) order of genesis may use the iris biometric features to enhance the security of Private Key and protect the user authentication systems against potential intruders (Bowyer, Hollingsworth, and Flynn, 2006). This is a significant melioration on the traditional cryptosystems where us er authentication primarily relies on the possession of secrete keys which may easily be forgotten, stolen or lost, and thus do non often provide nonrepudiation.Generally, the use of iris may provide a number of advantages and solutions to some of these challenges facing the traditional cryptosystems. For example, iris based key generation method acting for cryptography together with generation algorithms can be used to effectively bind cryptographic keys with the biometric template of a user in such a way that makes it significantly impossible to reveal the key without a successful biometric authentication.The process of using iris based key generation method for cryptography to develop a user authentication system usually involves a number of steps. Firstly, the biometric data of the iris of an individual is acquired using sensors and then the distinctive features are extracted before enrolling the user for biometric authentication. Next, the data is then used to generate cryptog raphic keys which can be released whenever an authorized user key presents
