摘要:
When a viewer views content, it is reproduced by a reproduction procedure depending on a dynamic condition set in the content. Here, a content object data input unit obtains an externally-input content object. The content object is stored in a content object data retention unit, if necessary. The content object includes a reproduction rule and a content data. A reproduction rule evaluation and execution unit obtains the reproduction rule in the content object and performs processing in accordance with the reproduction rule. The reproduction unit reproduces a reproducible data specified by the reproduction rule evaluation and execution unit. An identifier management unit retains an identifier of a content object reproduction device and provides the identifier upon request. It is thus possible to reproduce in accordance with the reproduction rule set in the content object data and to control the reproduction procedure depending on the dynamic condition.

摘要:
A message delivery system for delivering a message to a user includes: a plurality of delivery systems (300A, 300B) which are run by a plurality carriers respectively and deliver information to subscribers to the respective carriers; and an ID management means (100). When a delivery means receives a request to deliver a message, the delivery means transmits to the ID management means a demand for user ID resolution to deliver the message. Upon receiving the demand for user ID resolution from the delivery means, the ID management means resolves a user ID to which the carrier running the delivery means can deliver and a delivery of the message in question has not been allocated, and returns the user ID as a user ID candidate to the delivery means. The delivery means delivers the message to the user identified by the user ID included in the user ID candidate.

For satisfying request level of anonymization and preventing a decline of information value, an anonymization device, includes: an anonymization unit which executes anonymization processing to a data set including two data or over with making each group of the data as a processing unit; an anonymous level setting unit which sets an adaptive anonymous level to each of the groups of the data set executed the anonymization processing; an anonymity judgment unit which judges whether or not the group satisfies the set adaptive anonymous level; and further the anonymization unit executes anonymization processing to the data set executed the anonymization processing based on the judgment result by the anonymity judgment unit.
摘要:
To determine a relation discrimination possibility of a pseudonymous-name communication identifier so that, in each communication layer, no mismatch occurs between a pseudonymous-name communication identifier whose relation can be discriminated and a pseudonymous-name communication identifier whose relation cannot be discriminated. The Relation discrimination possibility determination means 2 determines a relation discrimination possibility of a pseudonymous-name communication identifier of a specific communication layer among a plurality of communication layers to a designated one of relation discrimination possible and relation discrimination impossible. It determines a relation discrimination possibility of a pseudonymous-name communication identifier of other communication layers to relation discrimination possible or relation discrimination impossible according to which one of relation discrimination possible and relation discrimination impossible the pseudonymous-name communication identifier of the specific communication layer is.

摘要:
In order to perform communication while configuring a disclosure level on an attribute of a user to be disclosed to a communication destination to a designated disclosure level, there is provided a communication relaying device selecting means (2) that selects, among a plurality of communication relaying devices (401-403) capable of relaying communication to a communication destination terminal (501), a communication relaying device corresponding to a disclosure level designated as the disclosure level on the attribute of the user from among disclosure levels in multiple steps. There is provided a communication means (4) that communicates to the communication destination terminal (501) through the communication relaying device selected by the communication relaying device selecting means (2).

摘要:
A system for avoiding notification of unwanted information, which can reduce the chance of information becoming a subject of conversation that a communication partner does not want to know, during the communication with the partner. The system comprises an unwanted-information storage unit, a known information storage unit, a matching decision unit, and a warning output unit. The unwanted-information storage unit stores unwanted information items that a user does not want to know, in association with the users. The known information storage unit stores known information items that a user has already known, in association with the user. The matching decision unit finds a communication partner who knows an information item that a user does not want to know, on the basis of the known information items stored in the known information storage unit and the unwanted information items stored in the unwanted-information storage unit. The alarm output unit gives a warning to the user when the communication partner is found.
摘要:
It is not possible to identify a suitable random value that can increase the validity of data after adding a random data and causing the concealment of original data values.In the present invention, authorization information indicating at last one attribute that a user authorizes to be disclosed is associated with a user identifier and recorded; an attribute name indicating a first attribute is received; a second attribute is identified corresponding to a cumulative number wherein each attribute is indicated among the attributes that the authorization information indicating the first attribute indicates; an attribute value corresponding to the first attribute and second attribute of the user identified by the user identifier associated with the authorization information is acquired for each authorization information indicating the second attribute; the correlation between the first attribute and the second attribute is identified on the basis of the acquired attribute value; and a random number is generated for each attribute within a random value range that is a range in which the random number can take between the first attribute and the second attribute and that is identified on the basis of the identified correlation.
