Data for an electronic book is to be formulated readily. Such data for the electronic book, supplied by a publishing company, is data by variable formats, and hence are converted by an XML converter 21 into data of the XML format. A data converter 22 converts the data of the XML format, obtained by conversion by the XML converter 21, into data of the type that may be distributed to the user, while adding data designed for facilitating the handling as the electronic book. A copyright protection processing unit 23 adds the copyright information to the formulated data and encrypts the data as necessary. A distributing unit 24 holds the data for distribution and distributes the data it holds responsive to a user's request. An apparatus for formulating data for an electronic book is also provided.
7,509,685, "Digital rights management," assigned to SealedMedia (Oracle).
Digital rights are associated with a semi-unique node identifier obtained or calculated from characteristics of a mobile device attached to a consumer device, rather than with the node identifier of the consumer device itself. The user of the consumer device may access the digital rights management encrypted content (which may come from local persistent storage or a network) by attaching the mobile device to the consumer device. In this way, the rights can be associated with the node identifier of the mobile device, and the rights are thus usable for the consumer device to access the encrypted content.
