Abstract: A perceptual reaction analyzer transmits content to the terminals, receives the perceptual reaction information, generates perceptual reaction change information, estimates the presence/absence of interest of the users based on the perceptual reaction change information to classify the users into groups corresponding to the presence/absence of the interest, generates a certainty level which indicates a degree of certainty of the presence/absence of interest, and tries, for a low certainty user, an operation on the content corresponding to the perceptual reaction by which the same presence/absence of interest of the low certainty user is estimated again, based on the perceptual reaction information of a user of which presence/absence of interest is the same as the low certainty user.

Abstract: A personal-information managing apparatus includes: a usage permission policy managing unit to manage usage permission policy in which a boundary between usage permission and usage prohibition of personal information is defined; a personal information request receiving unit to receive a request for the personal information from the personal-information handling apparatus; a usage-permission issuing unit to obtain the usage permission policy corresponding to the received request via the usage permission policy managing unit, and to issue a usage permit corresponding to the usage permission policy and the requested personal information to the personal-information handling apparatus; a usage permit issue history managing unit to manage the issued usage permit and usage permission issue history relating to the personal information; and a credibility establishing unit to establish credibility of information exchange with the personal-information handling apparatus in relation to the issuing of the usage permit and

Abstract: An information management unit 12 of an information management apparatus 1 represents a device as an object by a service provided and data stored in the apparatus. The information management unit 12 further sends and receives an object by a communication unit 23 and manages a surrounding apparatus as a similarly modeled object. A device policy creating unit 24 defines from objects what kind of device state is desirable when the surrounding environment is constituted by a plurality of devices in particular states as a device policy, and changes a setting of the information management apparatus 1 according to the device policy.

Abstract: An information management apparatus includes a first control information setting unit that sets first control information for permitting use of information within a destination terminal to the information; a second control information setting unit that sets second control information for permitting the destination terminal to forward the information to the information; a displaying permitting unit that controls, when information set with the first control information is received from a source terminal, to permit the information to be used locally within an apparatus; and a forwarding permitting unit that controls, when information set with the second control information is received from a source terminal, to permit the information to be forwarded.

Abstract: A verification apparatus includes a storage unit storing a plurality of pieces of verification biometric information on a per group basis with personal identification information unmapped to the verification biometric information and a verification unit performing a 1:N verification operation on the verification biometric information of a verification target person read by read unit and the plurality of pieces of verification biometric information on a per group basis.

Abstract: A user authenticating apparatus stores user information where identification information to identify each of a plurality of users and biological information of each user are associated with each other, acquires identification information of the user, when the user starts to use a predetermined target, authenticates each user using the acquired identification information and the stored user information, as first authentication, stores the identification information of the user whose first authentication is succeeded as success information, acquires the biological information of the user, and authenticates each user using the acquired biological information and the biological information corresponding to the identification information of the users stored as the success information among the stored biological information, as second authentication.

Abstract: Biometric information registered for each user is held, user information being a plurality types of attribute information associated with each user is held, a possibility that the user requests authentication is predicted and a predicted value is calculated for each user by using the plurality types of attribute information contained in the held user information. When biometric information for an authentication request is accepted, the accepted biometric information is matched against the biometric information for a plurality of users determined based on calculated predicted values, and it is determined based on the result of the matching whether a person having entered the accepted biometric information is authenticated as the user.

Abstract: A personal-information managing apparatus includes: a usage permission policy managing unit to manage usage permission policy in which a boundary between usage permission and usage prohibition of personal information is defined; a personal information request receiving unit to receive a request for the personal information from the personal-information handling apparatus; a usage-permission issuing unit to obtain the usage permission policy corresponding to the received request via the usage permission policy managing unit, and to issue a usage permit corresponding to the usage permission policy and the requested personal information to the personal-information handling apparatus; a usage permit issue history managing unit to manage the issued usage permit and usage permission issue history relating to the personal information; and a credibility establishing unit to establish credibility of information exchange with the personal-information handling apparatus in relation to the issuing of the usage permit and
