A wearable computer includes: a first storage that permanently stores a first characteristic therein, the first characteristic representing a physical characteristic of an owner of the wearable computer; an obtaining portion that obtains a second characteristic, the second characteristic representing a physical characteristic of a user who wears the wearable computer; a determination portion that determines whether the user is the owner based on the first characteristic and the second characteristic; a first request portion that requests, when the user is determined to be the owner, to allow the user to log into another device; a second storage that temporarily stores the second characteristic therein; and a second request portion that requests, when the user is not determined to be the owner, to allow the user to log into that another device by sending the second characteristic stored in the second storage portion to that another device.

An information processing system includes a verification unit and an execution unit. The verification unit verifies biometric information acquired from users against preregistered reference information. The execution unit executes a process based on the number of times biometric information has been verified on a user basis in a predetermined period by the verification unit.

An image processing system includes a reception unit that receives an image forming instruction from a user, a retaining unit that retains the image forming instruction in association with the user, an acceptance unit that accepts an execution instruction from the user; an authentication unit that performs authentication of the user, and an image forming unit that executes the image forming instruction retained by the retaining unit in association with the authenticated user. The image forming unit executes the image forming instruction without accepting the execution instruction by the acceptance unit in a case where the authentication unit completes the authentication and cancellation of execution by the user is not present within a holding time.

An image processing apparatus includes: a display unit configured to display an operation screen; an acquisition unit configured to acquire biological information of a user performing operation using the operation screen, the biological information varying reflecting a state of the user; and a registration control unit configured to control operation of registering information on the operation screen and the biological information of the user in association with each other.

An image processing apparatus includes an acquisition part that acquires biological information on a user who makes the image processing apparatus execute a job, the biological information changing while reflecting a state of the user, and a registration control part that controls an operation for registering information on the job and the biological information on the user in association with each other.

An image processing system includes a reception unit that receives an image forming instruction from a user, a retaining unit that retains the image forming instruction in association with the user, an acceptance unit that accepts an execution instruction from the user, an authentication unit that performs authentication of the user, and an image forming unit that executes the image forming instruction retained by the retaining unit in association with the authenticated user without accepting the execution instruction by the acceptance unit in a case where the authentication unit completes the authentication.

A data processing apparatus includes a first limit unit, an acquisition unit, a registration unit, and a second limit unit. If user authentication has been performed for a user by using acquired account information, the first limit unit limits a service to be provided, in accordance with a use limit that is preset for each of authenticated users. If the user authentication has not been performed for the user, the acquisition unit acquires biological information of the user. The registration unit registers the acquired biological information and a use status of the service in association with each other in a database. The second limit unit limits the service to be provided, in accordance with the use status corresponding to the acquired biological information.

An information processing apparatus includes an image capturing unit configured to generate image data by capturing an image, an identification unit configured to identify a plurality of users based on the image data, a determination unit configured to determine a priority of the plurality of users, and a display unit configured to display a user interface for at least one user among the plurality of users according to the priority.

A peripheral apparatus is provided and includes a function of generating electronic data from an information medium. Upon detection of the information medium, the peripheral apparatus starts processing including generating the electronic data using information acquired from the detected information medium and transmitting the generated electronic data to a destination registered in association with a user of an authenticated wearable terminal within a predetermined range, based on communication with the authenticated wearable terminal.

An image forming apparatus that includes an image capturing unit capturing an image in front of the apparatus; a display displaying a screen; and a controller including one or more processors, the controller configured to function as: an acquisition unit acquiring a face image of a user from the image captured by the image capturing unit; an authentication unit authenticating, using the face image of the user acquired by the acquisition unit, the user who is within a first distance from the apparatus; a tracking unit tracking the user authenticated by the authentication unit; and a control unit causing the display to display a screen that is based on information corresponding to the user tracked by the tracking unit when the user has reached a position at a second distance from the apparatus, the second distance being shorter than the first distance.
