This document defines a technical solution for encrypting resources of EPUB publications, effectively registering a device certificate to providers and securely delivering decryption keys to reading systems included in licenses tailored to specific devices. This technical solution uses the passphrase-based authentication method defined in ISO/IECÂ TSÂ 23078-2 for reading systems to receive the license and access the encrypted resources of such digital publications.

This document describes three types of copyright protection technologies in use in the publishing industry: — DRM free protection, i.e. technologies which does not rely on content encryption but rather use content fingerprinting or watermarking, adequate for use cases where user convenience is the top priority; — user key-based DRM protection, adequate where user constraints are limited; — device key-based DRM protection, adequate where the transfer of publications from one device to another is severely constrained.

The ISO/IEC TS 22424 series supports long-term preservation of EPUB publications via a dual strategy. This document makes EPUB compliant with current practices of Open Archival Information Systems (OAIS) archives and technical requirements of repository systems. The former tend to rely on OAIS in their operations; the latter prefer to ingest electronic documents only in containers conforming to standards such as METS (Metadata Encoding and Transmission Standard). ISO/IEC TS 22424-1 considers EPUB features from a long-term preservation point of view.

The ISO/IEC TS 22424 series supports long-term preservation of EPUB publications via a dual strategy. This document considers EPUB features from a long-term preservation point of view. Some EPUB features are forbidden and some others required, depending on how they relate to a long-term preservation. EPUB publications constructed according to these guidelines are suitable for preservation. ISO/IEC TS 22424-2 makes EPUB compliant with Open Archival Information System (OAIS) and current practices of OAIS archives.
