| titleOfInvention | Eavesdropping prevention service provision method |
| abstract | (57) [Abstract] [Purpose] Regarding a method for providing an eavesdropping prevention service to a subscriber terminal, a subscriber terminal having an eavesdropping prevention service function provides an eavesdropping prevention service regardless of whether or not the communication partner has an eavesdropping prevention function. The purpose is to do. A wiretapping prevention station side device 4 having a wiretapping prevention decoding function and a wiretapping prevention coding function is connected to a switch switch 5 of the station, and a call from a subscriber circuit 3 of a telephone set A having a wiretapping prevention terminal side device 1 is transmitted. If it is judged from the call information that it is a control signal to the connection line of the wiretapping prevention terminal side device 7 of the other party, the exchange switch 5 is connected to the subscriber circuit 6 of the telephone set B without passing through the wiretapping prevention station side device 4. If it is determined that it is a control signal to the non-connection line of the wiretapping prevention terminal side device 7, the exchange switch 5 is configured to be connected to the subscriber circuit 8 of the telephone C via the wiretapping prevention station side device 4. |
