Abstract [en]

From the user point of view, security has shown to be ambivalent; on one hand it is felt necessary, but on the other hand it is felt disturbing. Authentication solutions, for instance, are designed to keep undesired and unauthorized users out; however, allowed users need to spend some effort and waiting time when logging into a system. The question remains to which extent this effort is perceived as positive as security is increased, or negative through the waiting time spent in the process. Excessive waiting times imply the risk of user churn. As there is a lack of such studies, this paper investigates user perception (Quality of Experience, QoE) of the response times (Quality of Service, QoS) of a web authentication procedure, in particular a login to a community web page. Comparing the results to well-known user perception of web performance, we show that the users perceive logins in a similar way as standard web pages, which means that similar limits on user patience apply. The derived QoE-QoS relationship, an exponential function, serves then as the basis for assessing the performance of authentication algorithms in the domain of user acceptability.

Pappret visar att fördröjningar vid webb-inloggning upplevs på nästan samma sätt än fördröjningar av "vanliga" webbsidor -- det är samma exponentiella sammanhang mellan upplevd tjänstekvalité (QoE) och svarstiden (QoS) som kan användas. upplevd tjänstekvalité, QoE, svarstid, QoS, inloggning, web
