Patent ID: 8561908

Claim:
An information processing system comprising: an IC chip, a client driving said IC chip to carry out predetermined processing to at least acquire data stored on said IC chip, and a server connected to said client by a communication network, wherein, said client includes: a processing-command requesting section configured to issue a request to said server as a request for transmission, by said server to said client, of an IC chip processing command, the IC chip processing command to be executed by said IC chip to carry out said predetermined processing to at least acquire data stored on said IC chip; an ID-acquisition-command sender section configured to pass on an ID acquisition command, received from said server as a command for acquiring a chip ID of said IC chip, to said IC chip; a chip-ID extraction section configured to extract said chip ID from response data received from said IC chip; and a processing-command sender section configured to embed said chip ID, extracted from said response data from said IC chip, into said IC chip processing command received from said server and to transmit said IC chip processing command embedded with said chip ID to said IC chip; said server includes: a command-group sender section configured to send both said IC chip processing command and said ID acquisition command with the same timing, at said request made by said client, as a request for transmission of said IC chip processing command to said client; and said IC chip includes: a chip-ID sender section configured to transmit the response data, having a portion of the response data include said chip ID, in response to said ID acquisition command received from said client; a chip-ID determination section configured to produce a result of determination as to whether or not said chip ID, embedded in said IC chip processing command received from said client, is identical with the chip ID of said IC chip; and a processing execution section configured to carry out said predetermined processing to at least acquire data stored on said IC chip in accordance with said IC chip processing command if said result of said determination indicates that said chip ID embedded in said IC chip processing command, received from said client, is identical with said chip ID of said IC chip.
