Abstract
Techniques of performing authentication involve comparing current user authentication factors with previous authentication factors selected from multiple users during a single authentication session. Along these lines, suppose that an authentication server receives current browser characteristics from a user computer during a current authentication session. Based on the current browser characteristics, the authentication server selects previous browser characteristics received from devices used by multiple users during previous authentication sessions. For example, the authentication server may select previous browser characteristics based on the whether any of the results of a modified, locally sensitive hashing (LSH) of the previous browser characteristics match any of the results of a modified LSH of the current browser characteristics. After the authentication server selects the previous browser characteristics, the authentication server compares those selected, previous browser characteristics with the current browser characteristics.
