A new authentication management model oriented on user's experience

Authenticating users connecting to online services, social networks or m-banking became an indispensable element of our everyday life. Reliable authentication is a foundation of security of Internet services but, on the other hand, also a source of users' frustration due to possible account blocking in case of three fails. In this paper we propose a model of authentication service management which helps in keeping a balance between the authentication security level and positive users' perception of this procedure. The proposed procedure allows a user more than three attempts of authentication by switching after two failures to a more secure authentication protocol keeping a balance between QoP and QoE measures. Finally, the procedure determines an optimal path of authentication using a decision tree algorithm.
