摘要： Content data encrypted with a content key, the content key encrypted with an individual key specific to an information sending device, and the individual key encrypted with a distribution key that is updated in a predetermined cycle, and supplied are sent to an information receiving device, and the information receiving device decrypts the individual key with the distribution key, decrypts the content key with the individual key, and decrypts the content data with the content key. Thus, the information sending device does not have the distribution key, and accordingly piracy of content data can be prevented with a simple configuration. Also, the information receiving device sends the content key and a playback command to other apparatuses. Thus, other apparatuses can play back contents using the playback command and the content key. Furthermore, the information sending device decrypts the content key with the distribution key before being updated, and stores the same. Thus, contents purchased by an advance order can be actually purchased regardless of expiration dates of the distribution key. Furthermore, usage right is passed from a first information receiving device to a second information receiving device different in registration information at the tome of using contents. Thus, contents can be used among information receiving devices different from each other in registration information.
摘要翻译：使用内容密钥加密的内容数据，用信息发送装置专用的专用密钥加密的内容密钥和以预定周期更新的分发密钥加密的单独密钥被提供给信息接收装置，并且信息接收装置用分发密钥解密单个密钥，用个别密钥解密内容密钥，并用内容密钥解密内容数据。因此，信息发送装置不具有分配密钥，因此可以通过简单的配置来防止内容数据的盗版。此外，信息接收装置向其他装置发送内容密钥和重放命令。因此，其他装置可以使用播放命令和内容密钥来播放内容。此外，信息发送装置在被更新之前用分发密钥对内容密钥进行解密，并且存储该密钥。因此，无论分配密钥的到期日期如何，都可以实际购买由提前订单购买的内容。此外，在使用内容的使用方面，使用权从第一信息接收装置传递到注册信息不同的第二信息接收装置。因此，可以在注册信息中彼此不同的信息接收装置中使用内容。

摘要： A user who repeatedly purchases the same electronic content is entitled to receive a discount price for the additional purchases. This is accomplished by establishing an “Accounting History” of accounting information that is prepared when the electronic content is repurchased. The price of the repurchased electronic content is set to “Discount Price,” which is less than the original price at which the electronic content was purchased for the first time. Since accounts are settled based on the accounting information with “Accounting History” set to “Discount Price,” the user who is purchasing the same content again can buy it at a discount price.
摘要翻译：反复购买相同电子内容的用户有权收取额外购买的折扣价。这是通过建立在回收电子内容时准备的会计信息的“会计历史”来实现的。回购的电子内容的价格设定为“折扣价”，低于首次购买电子内容的原始价格。由于根据“会计历史”设置为“折扣价”的会计信息结算账户，所以再次购买相同内容的用户可以以折扣价购买。

摘要： An information receiving apparatus receives identification information and encrypted identification information and makes a comparison between them to allow prevention of illegal utilization of contents data. Also, a data storage apparatus can record contents data encrypted by a content key and the content key so that the contents data can be reproduced on other apparatuses to improve versatility. Moreover, a management apparatus can manage the contents data in the data storage apparatus to allow other apparatuses to utilize it. And also, an information regulating apparatus can verify a signature on available data to prevent illegal utilization of the contents data. Furthermore, the data storage apparatus can store the content key, its handling policies, the contents data encrypted by the content key and its license conditions information so as to safely provide the contents data. In addition, an information recording apparatus can select favorite contents data and store it on the data storage apparatus. Furthermore, the information receiving apparatus can prevent utilization of provision-prohibited contents data by a provision prohibition list.

摘要： An information processor receives at a communication section thereof an encrypted content decryption key generated by encrypting, by a distribution encryption key, a content decryption key for decryption of a content encrypted by a content encryption key. The received encrypted content decryption key is sent to a content key decryption section where it is decrypted. The decrypted content decryption key and copy control code are sent to a content key encryption section where they are encrypted by an encryption key which can be decrypted at an external information processor, namely, a session key, to send an encrypted content decryption key with a copy control code to the external information processor via a communication section.
