Abstract: [Problem] To provide a communication terminal, a communication method, and a communication program which enable maintenance of stable communication quality even if radio wave interference occurs between radio communication networks. [Solution] A radio wave environment recognition unit 11 recognizes a radio wave environment. A radio wave interference detection unit 12 detects radio wave interference between an associated radio communication network and another radio communication network. When the radio wave interference detection unit 12 detects the radio wave interference, an interference avoidance unit 13 executes interference avoidance processing for changing a channel to be used or integrating the associated radio communication network and the other radio communication network on the basis of the radio wave environment recognized by the radio wave environment recognition unit 11.

Abstract: The rights management means grants derivative creation rights to a secondary creator based on a rights grant instruction indicating the granting of the derivative creation rights for first content created by a primary creator to the secondary creator. The calculation means calculates a contribution rate indicating a degree to which second content improves an evaluation of the first content based on evaluation information of indicating an evaluation of second content created by the secondary creator who owns the derivative creation rights. The payment amount determination means determines the payment amounts to the primary creator and the secondary creator based on the contribution rate.

Abstract: A data management device includes a generation unit, a registration unit, an output unit, an acquisition unit, a determination unit, and a key output unit. The generation unit generates a first secret key that is restorable by a predetermined number of distributed keys. The registration unit registers data encrypted by using the first secret key in a database of a data storage device. The output unit outputs at least one distributed key among the distributed keys used to restore the first secret key to a key management device. The determination unit determines whether to agree to permission of a use request for data in intention expression on agreement or disagreement performed. When it is determined to agree to the permission of the use request for the data, the key output unit outputs, to the key management device, a key necessary for restoring the first secret key.

Abstract: A communication node includes: a control information sharing unit which distributes a relay node reselection request; a transmission power control unit which adjusts transmission power based on the relay node reselection request; a reselection necessity determination unit which determines whether another communication node is to become a new relay node, and, in the case of determining that the other communication node is to become the new relay node, calculating priority of the communication node in the wireless ad-hoc network; and a relay node reselection request unit which performs a relay node reselection request process for transmitting a relay node reselection request included in the control information, depending on the priority.
