A data management system includes a detecting apparatus that detects an information processing apparatus and a server apparatus that controls access to data by the information processing apparatus. The detecting apparatus detects the information processing apparatus located within a predetermined area. The server apparatus includes a transmitter that transfers data to the detected information processing apparatus, the data being associated with access authority indicating whether or not the information processing apparatus is allowed to access the data, and circuitry that controls an access to the data from the detected information processing apparatus in accordance with the access authority associated with the data.

Data management system, data management method, and recording medium storing data management program

An information processing apparatus which updates a basic software package is disclosed. The information processing apparatus includes an encryption and decryption unit which stores values calculated uniquely from software and encrypts information based on the calculated values and decrypts encrypted information based on the calculated values. The basic software package includes a firmware authenticating module for authenticating a firmware updating file which includes new software for updating the basic software package, a value uniquely calculated from the new software, and a public key signature. The information processing apparatus further includes a software updating module which updates the basic software package by using the authenticated firmware updating file, and an encryption key managing module for encrypting again the information encrypted by the values based on a value changed by updating the basic software package.

Information processing apparatus, software updating method, and image processing apparatus

An image processing apparatus includes: a switch of a main power supply unit that is switched between ON and OFF in response to a user's operation so as to switch the power supply between a supply of power and an interruption of the supply; a first notification unit that sends an interrupt request notification for requesting to interrupt a process in a recoverable way to all of or a part of the applications being run if the switch of a main power supply unit is turned off; and a power supply control unit that interrupts the supply from the power supply when a time lapse, that is measured since a time when the notification unit has sent the interrupt request notification, exceeds a first predetermined time.

Image processing apparatus and method for interrupting a power supply in response to a user's operation or a kernel of the operating system to switch the power supply between a supply of power and an interruption of power to the apparatus, when a time lapse since an interrupt request notification was sent, exceeds one of a plurality of predetermined times

An image processing apparatus, a session managing method, and a session managing program allow an operator to change his or her role flexibly. The image processing apparatus comprises a session managing unit for managing information about an operator who is logged in as a session, and a role determination unit for determining a role of the operator. The session managing unit includes a login session unit that is generated upon login of the operator, and a subject unit that generates information indicating the operator, a group to which the operator belongs, and an existing role of the operator. Upon request for a role change from the operator, the login session unit requests initialization of the subject unit. The subject unit then generates information indicating a role after role change based on the role after role change that is confirmed by the role determination unit.

Image processing apparatus, session managing method and session managing program

An image processing apparatus is disclosed that includes an installation unit that installs an authentication package providing a function related to authentication; a signature confirmation unit that confirms whether an issuance source of the authentication package is an authenticated issuance source based on an electronic signature attached to the authentication package; and an authentication package confirmation unit that confirms the authentication package based on attribute information of the authentication package confirmed to be the authenticated issuance source by the signature confirmation unit. In the image processing apparatus, the installation unit installs the authentication package confirmed by the authentication package confirmation unit.
