Abstract

PURPOSE:To keep confidentiality by applying A/D conversion to an audio signal, writing the result on an IC card, entering a pass word and reading out the data from the IC card only when the pass word is coincident with a number stored in advance. CONSTITUTION:A subscriber of a multi-function telephone set uses a key pad 13 and a dial 14 to store (12) a pass word. In storing an input voice onto a memory IC card 30 by the subscriber of the telephone set 1, a switch 22 is turned on to input the pass word from the key pad 13. When the word is coincident with the pass word stored previously, an A/D, D/A converter 16 and a write circuit 17 are operated. In reading out the card IC 30, the telephone set is looked off, the switch 23 is turned on, the pass work is inputted from the key pad 13 and the converter 16 and the readout circuit 18 are energized when the number is correct and an analog voice is outputted from a speaker from a speech circuit 15. Then mis-storage is prevented and the secret is secured in this way.
