摘要

There are provided an information recording medium, an information processing apparatus, an information processing method, and a computer program, which can realize users' convenience for using content in accordance with a license and copyright protection. An information recording medium stores an encrypted content file including encrypted content, usage right information of the encrypted content, and encryption key information necessary for a decrypting process for the encrypted content. Thus, a user can acquire a license (usage right information) and key information necessary for decryption of the content, together with the content, from the information recording medium, without acquiring the license (usage rights) by connection to a license provider. Therefore, it is no longer necessary to perform a process of acquiring the license (usage rights) from the license provider when the content is to be used, whereby user convenience is improved, and license-based content copyright management can also be ensured.
