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： A user who is purchasing the same content again can buy it at a discount price. “Accounting History” of accounting information B prepared when the content is repurchased is set to ‘Discount Price.’ 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： 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： A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.

摘要： Disclosed are an information processing apparatus and an information processing method which execute person authentication and allows various services such as receiving of contents to be received, provided that the authentication is successfully passed. In the information processing apparatus for executing, by a connection to an external server providing various services such as contents transmission, a process such as receiving of contents, person authentication is executed by comparing a template acquired from a person identification certificate storing a template which is person identification data of a user using the information processing apparatus with sampling information input by the user, and a connection to the external server is executed provided that the authentication is successfully passed. In addition, the person identification certificate and the public key certificate are stored in a memory together with link information in which the person identification certificate and the public key certificate applied during a process of establishing a connection to the server are related to each other.

摘要： In a public key certificate using system, a template which serves as person identification data of a person requesting a public key certificate is obtained from a person identification certificate of the person, a person authentication is executed by comparing sampling information of the person against the template, and a public key certificate for the person is issued by a certificate authority on condition that the person authentication is established, thus reducing the load on the certificate authority for person authentication. The public key certificate issued to the user is deleted upon completion of a processing session involving use of the public key certificate, restricting the use of the public key certificate to the particular processing session.
