Abstract
An information processing device includes a lock section, a creation section, a transmission section, a reception section, and a release section. The lock section disables an authorization function of the information processing device under a given condition. The creation section creates a first lock release file that is capable of releasing the authorization function disabled by the lock section. The transmission section transmits the first lock release file to an information management device. The reception section receives a second lock release file, which is based on the first lock release file, from the information management device. The release section tries to enable the authorization function of the information processing device when the second lock release file is determined to be valid.
