PROBLEM TO BE SOLVED: To identify a user more reliably on the side of an information receiver such as a printer. SOLUTION: Sound input units 102, 105 connected, respectively, with a computer 101 and a printer 104 can input the voice of a user, as a digital signal, to the computer 101 and the printer 104. The computer 101 transmits print data to the printer 104 along with an encrypted feature amount of voice. An operating section 103 controls the computer 101, generates and edits print data, extracts the feature amount of voice from the voice and encrypts it. A cable 106 connects the computer 101 with the printer 104. The printer 104 matches an encrypted feature amount of voice inputted from the input unit 105 with a decrypted feature amount of voice and prints out the print data upon matching. |
