摘要： There is provided a content use management method capable of preventing unauthorized distribution of a content and improving user-friendliness. In this method, the same group key is stored in a secure device (400) and a playback terminal (500). Moreover, a license issuing application is received from a license distribution server (200) and stored in the secure device (400). After this, a license encrypted by the group key is sent to the playback terminal (500) and the license encrypted by the group key is stored in the playback terminal (500). Upon playback of the encrypted content, the playback terminal (500) decrypts the license by using the group key and acquires the content decryption key, thereby decrypting the encrypted content. Even when the encrypted license flows into the network, it cannot be decrypted by a playback terminal not having the same group key and the copyright is protected. Moreover, the playback terminal (500) which already holds the group key and the license encrypted by the group key does not need the secure device when reproducing the encrypted content.

摘要： A package management information recording section 131 creates a directory for each package for content distributed in package units, and creates a package management file indicating the relationship between a directory name and package identifier. A content file recording section 132 creates a content file group management file indicating the relationship between a content file name and a reference name when that content is linked from other content. A link resolution information recording section 133 creates a link resolution file indicating the correspondence between a reference name indicating content included in another package and the package identifier of the other package. A link resolution section 142 of a content playback apparatus 140 specifies a link destination content file using these items of file management information. By this means, a link between contents can be maintained even when distributed content is recorded with a name different from the original content file name.

摘要： The invention is directed to a device that carries out secure distribution of a license particularly necessary for using a digital content in a copyrighted digital content distribution system. By a method of distributing a license according to the invention, a license encryption key for distribution is produced by a license distribution server based on a seed produced on the user terminal side according to a prescribed function F and the user terminal transmits a license based on the same seed and the same function F by a common-key method in a tamper resistant module. On the user terminal side, the stored seed is deleted once the license is decrypted.

摘要： A package management information recording section 131 creates and records on a recording medium 120 package management information for managing packages recorded on the recording medium 120. A content file recording section 132 records on the recording medium 120 content files of content file groups included in packages, and also creates and records on the recording medium 120 content file group management information for managing these content file groups. A content/metadata correspondence information recording section 133 creates and records on the recording medium 120 information on correspondence between content files and metadata files within a package or correspondence between a package itself and metadata files. By this means, the correspondence between content files and metadata files can always be maintained correctly when they are recorded separately.

摘要： A recording apparatus is provided for an SD memory card that has a plurality of EPUBxxx.KEY files recorded thereon, each file having a plurality of Key&Rule Entry areas, and an SD_EPUB.MMG file being read from the recording medium prior to the writing of data. A bitmap in SD_EPUB.MMG shows for each EPUBxxx.KEY file whether the EPUBxxx.KEY file has at least one Key&Rule Entry area not in use, or whether all the Key&Rule Entry areas are in use. Based on the bitmap in the read SD_EPUB.MMG file, the recording apparatus opens EPUB#u.KEY having an unused Key&Rule Entry area and writes data into the unused Key&Rule Entry area in the file. If all the Key&Rule Entry areas in EPUB#u.KEY become in use as a result of the writing of the data, the recording apparatus updates the bitmap in SD_EPUB.MMG.
摘要翻译： 提供了一种用于SD存储卡的记录装置，其中记录有多个EPUBxxx.KEY文件，每个文件具有多个密钥和规则输入区域，以及在写入数据之前从记录介质读取的SD_EPUB.MMG文件 。 SD_EPUB.MMG中的位图会显示每个EPUBxxx.KEY文件，无论EPUBxxx.KEY文件是否至少有一个“关键和规则输入”区域未使用，还是所有的“关键和规则输入”区域都在使用中。 基于读取的SD_EPUB.MMG文件中的位图，记录设备打开具有未使用的密钥和规则输入区域的EPUB＃u.KEY，并将数据写入文件中未使用的密钥和规则输入区域。 如果作为数据写入的结果，EPUB＃u.KEY中的所有Key＆Rule Entry区域都被使用，则记录装置更新SD_EPUB.MMG中的位图。

摘要： With content management apparatus 110 serving as a copy origin and storage medium 120 as a copy target, the copy origin retains allowed copy count control information on content, and when the content is copied from the copy origin to the copy target, the allowed copy count control information retained at the copy origin before copy processing is updated in accordance with a predetermined rule to generate allowed copy count control information to be retained at the copy origin and allowed copy count control information to be retained at the copy target, and subsequent copy processing at the copy origin is done based on the allowed copy count control information retained at the copy origin, whereas subsequent copy processing on the content stored in storage medium 120 is done based on the allowed copy count control information stored in storage medium 120. In this way, it is possible to achieve content management which is easily understandable for users.

摘要： An installation error estimating device has a predicted pattern acquirer which obtains a predicted positioning distribution pattern, which is obtained by computing a characteristic pattern of a predicted positioning distribution obtained by predicting a logical positioning distribution, at each observation point where a wireless tag is installed for positioning; and an observation data inputter to which positioning results obtained from the wireless tags by a tag reader are input as observation data. A dispersion pattern analyzer computes a characteristic pattern of a measured positioning distribution, which is obtained by statistical analysis of the applicable positioning result, as a measured positioning distribution pattern at each observation point based on the observation. An installation error estimator computes the installation error for the tag reader using the predicted positioning distribution patterns obtained and the measured positioning distribution patterns computed.
