An information management apparatus includes: a confidential data storing section configured to store a plurality of individual identifies (IDs) and data which is related to each of the plurality of individual IDs as confidential data. A receiving section is configured to receive a first search condition used to acquire desired confidential data to be transmitted from a first service providing unit. A searching section is configured to extract first candidate data which matches to the first search condition from the confidential data storing section. A transmission record storing section is configured to store a plurality of anonymized data which has been already transmitted to the first service providing unit. An anonymizing section is configured to generate first transmission data by carrying out processing to contain said first candidate data and the first data of the plurality of anonymized data based on first data which has data of a same kind as the first candidate data. A transmitting section is configured to transmit the first transmission data to the first service providing unit.

An information processing device for anonymizing personal information being linkable to an individual includes an anonymization policy providing unit which provides an anonymization policy in which priority is added to each of a plurality of kinds of anonymization processes to enhance anonymity for at least one item which can be related to said personal information; an anonymization process selecting unit which selects in sequence from an anonymization process of low priority to an anonymization process of high priority, in case said plurality of kinds of anonymization processes being contained in said anonymization policy which said anonymization policy providing unit provides is applied; an anonymization processing unit which applies said plurality of kinds of anonymization processes in said sequence selected by said anonymization process selecting unit to said personal information which an information user uses; and an anonymity evaluating unit which provides said personal information to which said anonymization process was applied up to the anonymization process concerned to said information user, in case it is judged that said personal information to which said anonymization process was applied had anonymity.

An information management apparatus receives position data from each terminal device. The position data contains position measurement data showing its positions at multiple clock times and its user identification data. The apparatus creates action history for every user based on the position data, and abstracts the position data in the action history. The apparatus includes an abstracting section and a testing section. The abstracting section abstracts arbitrary position data in the action history of a certain user. The testing section extracts another action history of another user. The other action history includes position data of the other user which shows a position same as or included in a position of the abstracted position data of the certain user, but excludes position data of the other user which shows positions same as remaining position of the certain user. The testing section outputs the abstracted position data as anonymity data.

A data use status tracking systemincludes: a terminal devicethat generates and transmits data; and a manager devicethat receives the data transmitted from the terminal device. The manager deviceincludes: a process history storing unit; a processing unitthat processes the data received from the terminal deviceand registers a process history including the process details of the data in the process history storing unit; and a referring unitthat receives a process history reference request designating a part or all of the process histories registered in the process history storing unitfrom the terminal deviceand transmits, as a response, out of counting results obtained by counting the process histories designated by the process history reference request with respect to a plurality of counting items, the counting result related to the counting item according to the type of the terminal deviceto the terminal device

An information management apparatus includes: a data receiving section, a collected data storage section, an aggregating section, a feature extracting section, a determining section, and an evaluation data storage section. The data receiving section periodically receives action data showing an action of a user. The collected data storage section stores the action data received by the data receiving section every user. The aggregating section generates a data set every user by aggregating action data containing an approximate content, of the action data stored in the collected data storage section. The feature extracting section extracts an index and a reference showing privacy confidentiality of the data set as a feature to incorporate in the data set. The determining section determines whether or not the privacy confidentiality of the feature of the data set is equal to or higher than a predetermined level. The evaluation data storage section stores the data set which passed the determining section.

In an information management apparatus, a data receiving section receives position data periodically from a plurality of mobile terminals. A second extracting section generates a power set to at least one position data, and generates a node composed of identification data of a user and object data as elements. A processing section registers on a node, a movement data set having as an element, at least one of the position data showing a position before movement to a position shown by the object data and the position data showing a position after the movement from a position shown by the object data. An abstracting section abstracts the object data an abstraction scheme with a priority determined according to the number of times of abstraction. A testing section lists up other nodes, each of which is different from the node of the object data in identification data, and same as the node in the object data, and which has a movement data set, of which a product with the movement data set of the node is an empty set, and output the object data of the node as anonymity data when the number of other nodes is equal to or more than a predetermined threshold value.

In an information processing system in which processing to be performed on a plurality of processed devices is shared and executed by a plurality of processing devices, load sharing is performed in units smaller than a processing request unit created. A request storing section of a main device stores a processing request including description of a plurality of devices to be processed which are processing objects and description of a processing content to be performed thereon. If the work load of an unexecuted processing request read out from the request storing section is heavy, a request dividing unit of each sub device divides the unexecuted processing request into a processing request including description of processed devices of the number commensurate with the processing by a processing unit and description of a processing content to be performed thereon, and a processing request including description of the remaining processed devices and description of a processing content to be performed thereon, and causes the processing unit to process the former processing request.

Provided is session control which enables profits of a web site to be optimized when accesses avalanche to the web site. A session control device connected to a web site and a client terminal which accesses the web site through a network, which includes a calculation unit for calculating, with a state of a session in each access to a reference page which is a page whose effect is large on arrival at processing whose importance in the web site is high as a stage, a tendency of a session toward the processing whose importance is high on a stage basis, a storage unit for storing a calculated tendency toward the processing whose importance is high, a setting unit for setting a reference for limiting the session, and a collation unit for obtaining, from the storage unit, a tendency toward the processing whose importance is high with respect to a stage of the session received from the client terminal and comparing the tendency with the reference to determine whether to limit the session from the client terminal.
