PROBLEM TO BE SOLVED: To provide an image processor and an image processing method capable of more flexibly and accurately starting the output of print information according to an instruction only from a legal user. SOLUTION: In processing 201 by a computer, voice data 310 read by using a voice inputting device are converted into cepstrum featured values by a prescribed method (311). The featured values are enciphered by using a public key 312 by a public key encipherment system (313), and enciphered voice featured values 330 are attached to print data 314, and the print data are transmitted to a printer. In printer processing 202, the featured values of voice data 320 read by using a voice inputting device are extracted (321). Moreover, the data transmitted from the computer are decoded by using a secret key 322 (323), and the decoded voice featured values 330 are collated with the read voice featured values (324). |
