Abstract: An information processing apparatus includes a determination unit configured to determine whether data including identification information of a user satisfy a condition to conceal the identification information, the data being generated when the user uses an apparatus, the condition being stored in a condition storage; a concealing unit configured to execute a concealing process to conceal the identification information included in the data when the data satisfy the condition; and a data storage configured to store one of the data including the identification information and data including the concealed identification information.

Abstract: An authentication system includes a device; and an information processing apparatus connected to the device. The device includes a state management unit that manages an authentication state in the device and causes the device to enter a log-out state; and a first communication unit that transmits an authentication scheme available in the device to the information processing apparatus when the device enters the log-out state. The information processing apparatus includes a second communication unit that receives the authentication scheme; a generation unit that generates a log-in screen based on screen setting information corresponding to the received authentication scheme; and a display controller that controls to display the log-in screen on a display unit.

Abstract: An electronic apparatus includes an information presenting part that obtains the job information of a stored first job of a first user who has logged on to the electronic apparatus and the job information of a stored second job of a second user who has authorized the first user to execute the second job from a computer connected to the electronic apparatus, and presents the obtained job information to the first user; and an execution control part that, when one of the first and the second job is selected and instructed to be executed by the first user, obtains the job data of the one of the first and the second job from the computer and execute the obtained job data. The first user and the stored first job are correlated and managed and the first user and the second user are correlated and managed in a predetermined storage area.

Abstract: An apparatus includes a reading unit that reads a first value indicating usage of the apparatus from a portable storage medium, a use limiting unit that updates the first value according to use of the apparatus and limits use of the apparatus when the updated first value reaches a predetermined value, and a writing unit that writes the updated first value into the portable storage medium.

Abstract: An image forming apparatus includes application programs that generate logs, an interface information storing unit configured to store interface information for the respective application programs, and a log management unit. The interface information is used to obtain the logs generated by the corresponding application programs. The log management unit is configured to receive a log acquisition request, to obtain the logs of one or more of the application programs specified in the log acquisition request based on the corresponding interface information stored in the interface information storing unit, and to output the obtained logs as a response to the log acquisition request.

Abstract: An information processing apparatus includes a display unit and a plurality of applications. Based on a transitionable application list including screen transitionable applications, GUI parts for selecting the screen transitionable applications are displayed on an application screen of the display unit. When a GUI part is selected on the application screen, a screen transition is made to an application screen of the selected application, based on the transitionable application list that excludes the selected application.
