Abstract: An authentication system includes a user authentication unit. The user authentication unit performs user authentication by combining password authentication and handwriting authentication, the password authentication being performed by collating an entire character string of a password inputted using an operation input unit and a handwriting input unit with an entire character string of a registration password stored in a storage unit, the handwriting authentication being performed by collating the handwriting information of a part of characters of the password inputted by the handwriting input unit with handwriting information of handwriting data of this inputted character stored in the storage unit.

Abstract: An image forming system includes a plurality of processing apparatuses. An image forming apparatus includes an image forming section, storage, an acquiring section, a first specifying section, a receiver, a second specifying section, and a notifying section. The storage stores therein a position of each of the processing apparatuses. The acquiring section acquires state information from each of the processing apparatuses. The state information indicates whether a corresponding one of the processing apparatuses is in a normal function state or a malfunction state. The first specifying section specifies, from among the processing apparatuses, a malfunctioning processing apparatus for which the malfunction state is indicated by the state information. The second specifying section specifies a relative position of the malfunctioning processing apparatus with respect to a mobile terminal device.

Abstract: An information processing apparatus includes a generation processing portion, a presentation processing portion, and an authentication processing portion. The generation processing portion generates a password. The presentation processing portion presents, in such a way as not to pass through an external device, the password generated by the generation processing portion to a mobile terminal associated with an authentication-target user. The authentication processing portion authenticates the user when the password is input after the password is generated by the generation processing portion.
