A data processing system (100) comprises: a database (4); a host computer (3) and a user computer (1) capable of communicating with each other over a network (2); wherein the user computer sends a data request message (RQ) to the host computer (3), the request message containing Data information (RD), Identity information (RI), and Authenticity information (A; VI), wherein the host computer (3) checks the authentication information and only sends the required data if the Identity information (RI) defines an authorized user and the authentication information (A; VI) authenticates the user identification information. The request message further contains secondary information (RT) and the host computer (3) calculates, from the secondary-information, a reliability value (R), compares the calculated reliability value with a predefined reliability threshold, and sends the required data only if the reliability value is at least as high as the reliability threshold. |
