Abstract: A content management method and content storage system are provided in which a content key encrypted with a first storage key and stored along with a content encrypted with the content key in a first content storing means is decrypted with the first storage key, the content key obtained by the above decryption is encrypted with a newly generated second storage key and stored along with the encrypted content in a second content storing means. Thus, the content management method enables to safely duplicate (back up) a content while preventing the content from being copied fraudulently.

Abstract: A system in which content usage conditions can be upgraded without the need for a service provider to control content-usage rights of a user. In the system in which encrypted content is distributed and is allowed to be utilized only by authorized users, the service provider receives a content usage-right certificate from the user, and on the condition that it is determined that data is not tampered with by verifying a digital signature of an issuing entity of the content usage-right certificate, the service provider obtains user information and content purchase information of the user from the content usage-right certificate, and performs upgrade processing by, for example, changing the usage conditions. It is thus possible to change the content usage conditions without the need for the service provider to possess usage control data.

Abstract: An information processing method includes the steps of: detecting a magnetic field variation that occurs in the vicinity of a receiving section that receives a magnetic field signal; determining whether or not a detection result satisfies a predetermined condition that is set in advance; connecting a storage section, which stores information included in the magnetic field signal received by the receiving section, to the receiving section if it is determined that the detection result does not satisfy the condition; and connecting the storage section to a reading section that reads information stored on the storage section, if it is determined that the detection result satisfies the condition.

Abstract: 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.

Abstract: The present invention allows content to be transferred with source equipment retaining the content. Content is transferred to destination equipment while at the same time it is retained on the source equipment. This allows the content to be used on both source and destination equipment in contrast to the usual move operation in which content is removed from the source equipment and used only on the destination equipment. While content is under transferred control, the source equipment cannot transfer the control of the content to any third equipment. Thus, the content is held only on the two pieces of equipment: the source equipment and destination equipment. In this respect, content control transfer differs from the first-generation duplication which can produce multiple duplicates (first-generation) from the original content. Also, content control transfer differs from one-time duplication in that content control can be transferred to third equipment if the content is returned from the source equipment.

Abstract: A person authentication system capable of performing personal authentication by comparing templates that is personal identification data with sampling information input by a user is disclosed. For example, a service provider (SP) or a user device (UD) acquires the templates from a person identification certificate (IDC) generated by a personal identification certificate authority that is a third party to thereby perform personal authentication. The IDC stores data, such as a certificate identifier and a user identifier, in accordance with a format, and also stores encrypted templates in a manner that the data can be decrypted by an entity that performs authentication. This arrangement achieves efficient template retrieval and a personal authentication process, as well as effective prevention of the templates from being leaking out.
