Abstract
An information processing apparatus includes: a memory in which an apparatus-unique key is stored, the apparatus-unique key being a key that is unique to the information processing apparatus; an input section that inputs user operation information; a communication section that performs data reception processing; a data processor that executes validity determination processing for the apparatus-unique key; and an output section that outputs a result of the validity determination processing executed by the data processor. The data processor receives, via the communication section, key-validity determination data for determining whether the apparatus-unique key is valid or invalid. The data processor also executes the apparatus-unique-key validity determination processing by using the key-validity determination data in response to a user instruction input via the input section, and outputs a result of the validity determination processing to the output section.
