  • Patent number: 7295832
    Abstract: An identification information transmission pathway is separated from a system side to be performed by a mobile authorization means of an owner of a security module in a wireless way. To this end, the security module comprises two interfaces, i.e. one for a communication with a terminal and a further one for wirelessly communicating with the mobile authorization means. The mobile authorization means supplies identification information to the security module for an authentication examination at its part, either stored in the authorization means in a memory or otherwise generated there, like e.g. via biometric sensors, via a keyboard or the like. The security module, performing the examination of the identification information, like e.g. preferably via a zero knowledge method or a zero knowledge protocol, respectively, only then indicates a request for an action at the terminal, like e.g. of a money transfer, when the examination is successful.
