Traditional means of user authentication include usernames and passwords or externally generated codes. However, lately biometric methods, which are based on user\u2019s natural features, have gained popularity as well. Biometry is utilized, for an example, in high-security access control, national border control and personal mobile phones.The aspects of data security and usability are crucial for creating biometric systems, which achieve the required security level, while maintaining the user-friendliness and reasonableness of using the service. Lack of proper security might cause sensitive data to end up in the wrong hands. However, data security might be an invisible and unknown area for some users, while usability is tightly connected to user satisfaction and also affects buying decisions greatly. This thesis studies data security and usability in biometric user authentication technologies, emphasizing the methods of user authentication via fingerprint and iris recognition. The thesis aims to identify the main problems of data security and usability in these methods, and the steps, which have been taken to adjust them. The meters of evaluating data security and usability on biometry was also researched. The thesis was conducted as a literary review mainly based on conference and journal articles on the field of information systems. It was perceived, that biometric authentication includes usability problems which are caused by innate features, aging, working history, accidents or environmental effects. To adjust these problems, methods of improving the algorithms, user interfaces, devices and imaging have been suggested. The greatest problem in the area of data security was found to be the lack of different, unique biometric samples in a human being, and the absence of possibilities in changing and replacing those samples. To overcome this problem, many methods and algorithms of cancelable biometrics have been created.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Akseli Liljander (akpealli) on 2016-04-19 07:39:49.752833.
