Method and system for user authentication

A system of user authentication in a telecommunication network, the system including an authentication server with an authentication service, and further comprising

• a receiver configured to receive previous behavior information of a user, wherein the previous behavior information of the user comprises at least one previous parameter used in one or more identity checks, and wherein the previous behavior information is based on previous behavior patterns of the user received and collected from one or more service providers in connection with the user's use of services provided by the one or more service providers, respectively, at least one of the one or more service providers including a prior service provider other than the authentication server;
• the receiver further configured to receive a request including at least one user behavior data for an authentication of the user after one or more threshold score values have been selected for the user,
• the request for the authentication including an at least one parameter of at least one behavior of the user, wherein the user is requesting a service of a service provider,
• the authentication server including:
• a memory configured to store the at least one parameter of the at least one behavior of the user received during the authentication,
• a non-transitory computer storage medium storing computer code, which when executed causes a computer processor to:
• perform a first identity check of the user for the authentication, the first identity check including:
• i) determine one or more score values based on the at least one parameter of the at least one behavior of the user and the previous behavior information of the user, and comparing the one or more score values with the one or more threshold score values to determine whether to pass the first identity check;
• and, based upon said comparing, selecting one of:
• iia) pass the user for the first identity check;
• or, in the alternative:
• iib) perform an additional identity check for a further authentication, further including checking of an identity of the user, if the first identity check of the user did not match with the one or more threshold score values for the user, by a score value different from one of the one or more score values.

A non-transitory computer storage medium storing computer program code which causes a computer processor to employ authentication in a telecommunication network including an authentication server with an authentication service, which when the computer program code is executed by the computer processor causes the computer processor to:

• provide previous behavior information of a user, wherein the previous behavior information of the user comprises at least one previous parameter used in one or more identity checks, and wherein the previous behavior information is based previous behavior patterns of the user received and collected from one or more service providers in connection with the user's use of services provided by the one or more service providers, respectively, at least one of the one or more service providers including a prior service provider other than the authentication server;
• receive, by the authentication server, a request including at least one user behavior data for an authentication of the user after one or more threshold score values have been selected for the user,
• the request for the authentication including an at least one parameter of at least one behavior of the user, wherein the user is requesting a service of a service provider,
• the authentication server including the computer program code which is further configured to:
• store the at least one parameter of the at least one behavior of the user received during the authentication,
• perform a first identity check of the user for the authentication, the first identity check including:
• i) determine one or more score values based on the at least one parameter of the at least one behavior of the user and the previous behavior information of the user, and comparing the one or more score values with the one or more threshold score values to determine whether to pass the first identity check, and, based upon said comparing, selecting one of:
• iia) pass the user for the first identity check;
• or in the alternative:
• iib) perform an additional identity check for a further authentication, further including checking of an identity of the user, if the first identity check of the user did not match with the one or more threshold score values for the user, by a score value different from one of the one or more score values.
