Abstract: An information processing apparatus that, when authentication is successfully performed by using first authentication information, permits access to first content. When authentication is successfully performed by using second authentication information which is different from the first authentication information, the information processing apparatus permits access to second content having a confidentiality level higher than a confidentiality level of the first content. The third authentication information is issued to a user in a period in which authentication using the second authentication information is valid. The third authentication information is different from the first authentication information and the second authentication information. When authentication is successfully performed by using both the first authentication information and the third authentication information, the information processing apparatus permits access to the second content.

Abstract: Provided is an information processing system including plural information processing devices each of which is accessible using first authentication information that is given to each of users, that varies among the users, and that is common to the plural information processing devices, access to a specific service from an accessed information processing device among the plural information processing devices being permitted using second authentication information that is given for the specific service to each of the users and that varies among the users. The information processing system includes a display controller and a storage controller.

Abstract: An information processing apparatus includes an authentication unit and an issuing unit. When authentication is successfully performed by using first authentication information received by a receiving unit, the authentication unit permits access to first content. When authentication is successfully performed by using second authentication information which is received by the receiving unit and which is different from the first authentication information, the authentication unit permits access to second content having a confidentiality level higher than a confidentiality level of the first content. The issuing unit issues third authentication information to a user in a period in which authentication using the second authentication information is valid. The third authentication information is different from the first authentication information and the second authentication information. The user is authenticated by using the second authentication information.

Abstract: An information processing device includes an acquiring unit configured to acquire second authentication information having an expiration date and required for authentication by an external device, by using previously stored first authentication information when an image is received; and a transmitting unit configured to connect to the external device by using the second authentication information, and transmit the image to the external device.

Abstract: A communication system includes an information processing apparatus and an image processing apparatus. The information processing apparatus includes an image data receiving unit, a memory, a processing identification data receiving unit, a processing-related data transmitting unit, and a processing unit. The image processing apparatus includes an image data obtaining unit, an image data transmitting unit, a processing identification data transmitting unit, a processing-related data receiving unit, and an image formation instruction unit.

Abstract: A managing device includes a request receiver that receives a request for use of an image forming apparatus, the request containing information concerning a user; an upper limit value determining unit that, upon receiving the request for use by the request receiver, determines an upper limit value for image formation processing on the basis of limiting information of a user group to which the user belongs; and a transmitter that transmits information providing an instruction to inhibit the image formation processing to an image forming apparatus whose image formation processing cannot be limited based on the upper limit value determined by the upper limit value determining unit when the processing upper limit value is less than a threshold value.
