Authentication in E-learning systems must be secure because many users access E-learning systems for educational purpose and information must be secure for each user. Many users choose E-learning systems because they offer the possibility to study online wherever they are. Also, users have the possibility to take the exams online based on the moment they havefinished the courses. The recognition of ocular retina can be implemented using biometric data that are integrated with artificial intelligence. Implementing authentication based on ocular retina can be done only by software developers because they have access to sources of informatic systems and they can modify them as many times as they are required. Biometric data is different for each user and its scanning is very important so that the authentication be successful. Authentication based on scanning ocular retina presents a big advantage regarding the security of each informatic system because any other user cannot have access to that system if he does not have personal biometric information saved in the database. For each user authentication is relatively easy because he just looks at the authentication page and next his ocular retina is authomatically scanned and then every biometric information is automatically sent to a database. Security plays a very important role in informatic systems because nowadays there are more and more attacks from unauthorized groups or persons towards different informatic systems in order to collect some information. In E-learning systems there is various confidential information for educational purpose and a very advanced security is necessary.
