Processing apparatus, mobile device, and non-transitory computer readable medium storing authentication request program

A processing apparatus comprising:

• a process execution unit that executes a process according to a user instruction;
• a first communication unit that performs wireless communication with a mobile device which is moved in a predetermined communication area;
• a recognition unit that recognizes existence/non-existence of user intention in which a user attempts to cause the process execution unit to execute the process, wherein the recognition unit is configured to determine whether the user moves toward the processing apparatus, and in response to determining that the user moves toward the processing apparatus, the recognition unit causes the first communication unit to transmit the inquiry about the existence/non-existence of use intention to the mobile device which is moved in the predetermined communication area and to receive a reply to the inquiry from the mobile device, and recognizes the existence/non-existence of use intention based on the reply;
• an authentication processing unit that, in cases where the first communication unit receives a user ID maintained in the mobile device through communication with the mobile device and the recognition unit recognizes that the user who possesses the user ID attempts to cause the process execution unit to execute the process, executes a user authentication process of recognizing whether or not the user who has the reception user ID received by the first communication unit is a user who has authority to cause the process execution unit to execute the process for at least a part of necessary authentication process among processes which can be executed by the process execution unit;
• and
• a process execution permission unit that, in a case where the reception user ID is recognized by the authentication processing unit as the user ID possessed by the user who has the authority to cause the process execution unit to execute the necessary authentication process, permits the process execution unit to execute the necessary authentication process,
• wherein the authentication processing unit inquires of an external device, in which the user ID of the user who has the authority to cause the process execution unit to execute the necessary authentication process is registered, about whether or not the same user ID as the reception user ID received by the first communication unit is registered as the user ID of the user who has the authority to cause the process execution unit to execute the necessary authentication process, and permits the process execution unit to execute the necessary authentication process in a case where the reception user ID is recognized as the user ID possessed by the user who has the authority to cause the process execution unit to execute the necessary authentication process based on a response with respect to the inquiry, as the user authentication process.
