<p><P>PROBLEM TO BE SOLVED: To make it difficult to identify which information processing apparatus communicates with which information processing apparatus even when a third party monitors packets transmitted through the Internet. <P>SOLUTION: A communication system includes a virtual address server that pools a plurality of virtual global addresses to be lent so that communication apparatuses tentatively use. When a first information processing apparatus communicates with a second information processing apparatus, the first information processing apparatus makes a request to the virtual address server for lending a virtual address. Based on the request, the first information processing apparatus transmits communication packets having an address of the second information processing apparatus as a destination address while the virtual address lent by the virtual address server is designated as a source address. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
