The publisher employs a tool to encrypt the content for viewing on a given machine or a group of related machines.
Requirement(s)
1) A methodology to authorize a machine or group of machines before premium content can be downloaded locally onto machine.
2) Encryption mechanism for content for a given authorized machine or machine group.
3) Viewing the content is not possible without decryption on authorized machine.

Comments
This requires specification to encrypt various content types, i.e., HTML5, EPUB, video content. This also requires support from DRM specifications. Tools to perform the required encryption and handle the DRM authorization aspects need to be in place for each type of content.
