Abstract

PURPOSE:To increase confidentiality by protecting not only a protocol but also a picture signal by a pass-word. CONSTITUTION:A data converting 4 part is provided, the execution of a confidential communication based on the coincidence of the passwords are recognized in the protocol in a communication control part 5 and compressed data to transmit are scrambled based on the pass-word and transmitted. On a receiving side, they are descrambled based on the same pass-word entered beforehand in a memory 2. A main control part 1 integrate-controls facsimile terminal equipment and is composed of a processor. Thus, the picture signal inputted from a reading recording control part 3 is guarded by the double pass-words and therefore, a confidential function can be improved.
