Abstract: A method and system for user authentication through mobility traces comprising: retrieving and processing (401, 411) data records stored in a network events database (14), the data records comprising data of one or more interactions (101) of the user with at least one network element (12) through a mobile device (11) of the user, a timestamp (T) associated with the recorded interactions, a unique identifier of the mobile device (11), a unique identifier of the user and a unique identifier of the network element (12); computing (103) at least one network interaction track, NIT, by using the retrieved data; using the at least one computed NIT (402, 412) to obtain an authentication result, e.g., based on a computed authentication probability (Pi), indicating either a success or a failure of the user authentication to be returned to a third-party service provider (21) requesting the user authentication status check (202, 302).

Abstract: The method comprises receiving web activity of an individual user from at least one user device and from at least one network; identifying, based on said received web activity, a first advertising-related activity from un-encrypted web resources; calculating a first monetary user value based on accumulated un-encrypted web activity logs characterized in that web activity; calculating a second monetary user value based on advertising-related activity from encrypted web resources; and calculating a final monetary user value by adding said first and second values from advertising-related activity.
