Estimation of the time for calculating the attributes of browser fingerprints in the user authentication task

This paper presents an overview of the essence of web space which may contain information required to identify and authenticate users on the Internet in order to prevent attempts at malicious acts. Essences with a common content or the same detection method are structured into groups. The greatest attention is paid to one of these groups of entities: «the browser fingerprint» group. An approach and software have been proposed that allow for automated search of the values of entities belonging to this group and for estimating the time of this search for a specific infrastructure in order to develop adaptive authentication mechanisms. Moreover, an analysis of the average time to calculate the values of attributes has been carried out for the most informative browser fingerprints.
