Server system and method for providing at least one service based on authentication dependent on personal identification data and computer specific identification data

A method for executing an application program on a user's computer, wherein the application program of the user's computer is executed via an application protection system installed on the user's computer, wherein the application protection system comprises an administration module and a running time monitor for starting and monitoring the application program, wherein

• the application program is started via the administration module and
• the running time monitor monitors the access of the application program to system files, when the application program is executed,
• the administration module, in an initialization phase, detects system files, provides them with an identification and stores them in a first registry of the user's computer, and
• it is examined, in the initialization phase, which system files are used by the application program, and such system files are provided with an additional identification and are stored in a second registry of the user's computer.

A method for providing at least one service via a server system, in which

• a user logs onto a server via a user's computer for obtaining access to a service offered by the server,
• the server requests personal identification data of the user for authentication and
• the server allows the user's computer access after successful authentication,
• wherein
• additional user's computer specific identification data are compared with identification data stored in advance on the server after successful authentication and
• authorization is granted to the user's computer to access the at least one service in dependency on the comparison of the user's computer specific identification data,
• wherein
• an application program of the user's computer provides the connection to the server,
• the application program of the user's computer is executed via an application protection system installed on the user's computer, wherein said protection system comprises an administration module and a running time monitor for starting and monitoring the application program,
• the administration module detects system files in an initialization phase, provides them with an identification and stores them in a first registry of the user's computer, and
• it is examined for an application program in the initialization phase, which system files are used by the application program, and these such system files are provided with an additional identification and are stored in a second registry of the user's computer.
