The present invention describes a method and a software module making it possible to secure communications with a sensitive application, for which exchanges with the outside have been delegated to a so-called interfacing application. To clearly indicate existence of characteristic words and phrases which do not appear as cooccurrence words and phrases for other components of the analysis axis, it is desired to appropriately present distinguishable features between the components to the user. When the virtual connection releasing is initiated, the evolved Access Network sends the A9-releasing-A8 message, which carries the PMIP indication, to the evolved Packet Control Function. A software program interprets the stroke and applies it to the placement or posing of the corresponding element. The system may determine first positions and the second positions of the corresponding features using the first camera image and the second camera image.
