[ANGLÈS] Nowadays, there is a great bunch of applications implementing authentication processes in order to protect user access and users' data. Accessing our mobile device, doing a bank transfer or getting engaged with e-commerce are examples of how the great majority of population is in touch with an authentication process. The most common system to log in web applications is the use of pairs (username, password). It could be said that is rather contended but at the same time could imply problems, normally related to the strength or weakness of the used passwords. On the one hand, if strong passwords are used, users tend to forget them. On the other hand, if weak passwords are used, a non-legitimate user could impersonate a legitimate account attempting against the user's privacy. Bearing this in mind and taking into account that biometrics systems are securer and by far more user-friendly, in this TFG we propose an implementation of a web authentication process based on users' fingerprints. The proposed system is an externalized and standardized solution and, therefore, webApps wishing to use it could be easily integrated. For demonstration purposes, we have implemented three different entities: first, an authentication and authorization server, the authServer; second, a mobile application which stands for the authClient; and finally third, a dummy web application, the webApp. Being the webApp the application that the client will see in its device, the registry and authentication process will be performed by the authClient and authServer in a barely imperceptive way for the user.
