The invention relates to a method and arrangement for securing a man-machine dialogue between a user and at least one application, which may be executed on a terminal, whereby a communication between user and application is achieved by means of input channels and output channels on the terminal. According to the invention, the user can be given the security that he is communicating with only one particular application, whereby the input channels and/or the output channels of the terminal, together or separately, may be optionally switched by means of a switching device such that only the particular application is available.

Method and arrangement for securing a man-machine dialogue

A method for providing and billing WIM functionalities in mobile communication terminals. The method is characterized in that the WIM internally counts each of the signatures initiated by the subscriber, wherein the signature function is blocked when a given number of signatures has been reached. No further signatures are possible until the counter has been reset by means of a release/reload-type operation and a corresponding billing has taken place.
