摘要

A method for preventing fraud or misuse based on a risk scoring approach when using a service of a service provider requested by a user equipment includes: in connection with a first occurrence of providing the service, the service provider transmits a request message to a subscriber database, the request message being related to the MSISDN of the user equipment, and the request message requesting additional data related to the user equipment and/or the subscriber identity module; the service provider receives an answer message from the subscriber database, the answer message comprising the additional data; and in connection with a second occurrence of providing the service, an authentication information is transmitted between the service provider and the user equipment without transmitting a request message and a corresponding answer message.
