<P>PROBLEM TO BE SOLVED: To perform secure communications without slowing down performance of MFP. <P>SOLUTION: In a printing system, an information processor for storing document data is connected to one or more image-forming devices through a network. The information processor comprises: encryption means for, when receiving a print execution request including a document ID to identify document data, using predetermined information to encrypt the document data shown by the document ID; first transmission means for transmitting the data encrypted by the encryption means to the image-forming devices without protecting a communication channel; and second transmission means for transmitting the predetermined information to the image-forming devices with protecting the communication channel. The image-forming devices comprise: decoding means for using the predetermined information received from the information processor to decode the encrypted data; and printing means for printing the data decoded by the decoding means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
