摘要： PROBLEM TO BE SOLVED: To provide a communication technology with which, even in a case where reachers share a plurality of pieces as a part of contents distributed in a content distribution system, when a key is disclosed, the effect can be reduced. SOLUTION: A preferential piece index selecting section 522 selects, as a preferential piece index, a piece index (j) in an encryption piece column having most non-transmitted encryption pieces among encryption pieces stored in a seeder 52. When a piece request is received, a piece index determining section 523 determines a piece index (j) of an encryption piece with the piece index (j) selected as the preferential piece index as a transmission candidate. A variation index determining section 524 determines an encryption piece to be transmitted, from among encryption pieces which belong to an encryption piece column corresponding to the determined piece index (j) and that the variation index determining selection itself is holding.

摘要： PROBLEM TO BE SOLVED: To provide an information processing technique capable of accurately detecting watermark information, even in the case that the watermark information is separated and embedded to content by a temporal segment.SOLUTION: An information processor extracts a feature amount of content, and detects a position where a change in the feature amount in the content is larger than a first predetermined amount. When embedding watermark information including a plurality of components each corresponding to each segment to the content, the information processor embeds each component to the content depending on each segment between each of all or part of the detected positions and a first predetermined length, and outputs the content to which the watermark information is embedded. In the case that the position where the change in the feature amount is larger than the first predetermined amount cannot be detected in a second predetermined length segment in the content, the information processor selects the position depending on magnitude of the change in the feature amount in the second predetermined length segment in the content.

摘要： PROBLEM TO BE SOLVED: To provide a communication technology with which a combination of encrypted pieces to be distributed in a content distribution system is made unique for each communication apparatus and a degree of freedom in system construction is improved.
SOLUTION: When a node 51 receives a node ID sequence, a random number sequence and encrypted pieces from other nodes 50, 51, the node 51 correspondingly stores them. In a case where there is a piece request from the other node 51, the node 51 determines in terms of probability whether to perform encryption or not and when performing encryption, a random number and a private key are used to generate temporary symmetric keys, so that the encrypted pieces are further encrypted using the temporary symmetric keys. When encryption is not performed, the node 51 generates a substitutive random number. Then, the node transmits to the other node 51 a node ID of the node's own in addition to the node ID sequence stored correspondingly to the encrypted pieces, a random number generated by the node itself in addition to the random number sequence stored correspondingly to the encrypted pieces, and the encrypted pieces.
