Abstract

An information processing apparatus includes: a data processor which creates content to be distributed to a client, wherein the data processor executes processing of creating content provided to a client by selecting data in units of segments, which are division data of content, from a plurality of additional information recorded content items obtained by recording different additional information items on original content, selects different segment columns in units of content distribution clients in the processing of creating content provided to a client, and creates management information in which client information for identifying a client of a content distribution destination and segment column information indicating a segment selection state of the content provided to a client, which is provided to a corresponding client, are matched with each other and records the management information in a storage unit.

Description

technical field [0001] The present disclosure relates to an information processing device, an information processing method, and a program. In particular, the present disclosure relates to an information processing device, an information processing method, and a program used in a system capable of preventing unauthorized use of content or tracking a source of illegally distributed content. Background technique [0002] In recent years, data communication via a network such as the Internet has become popular, and a large amount of image data, music data, and the like are actively distributed via the network. [0003] For many contents, such as image data or music data, its creator or distributor holds the copyright, the right to distribute, and the like. Therefore, for example, when a service provider provides content from its server to users via a network, control is generally performed so that only users with legal rights are allowed to use the content. [0004] As a spec...
