    摘要: A sampled-value code processing device in which, from the sampled-value code series input at a predetermined period, a first code series consisting of codes related to a group of sampled values determined according to a prescribed rule and a second code series consisting of codes related to sampled values other than the group of sampled values are each produced at a period longer than the predetermined period, and a filtering process for the first code series is performed by using the second code series.

    摘要: 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.

    摘要: The information signal transmission system of the present invention is so designed as to convert the analog information signal into digital information data and to transmit these digital data after enciphering a part of the digital data. It can therefore maintain the secrecy of the transmitted information signal and can employ a low-speed enciphering process, thereby reducing the magnitude of hardware and reducing its cost.
