Abstract

The present invention relates to methods of and systems for providing conditional access to electronic content. Electronic content is provided to a user along with authorization information. The electronic content may be transmitted to the user, and the user may use the authorization information to access the electronic content. An authorization code may be provided to the user such that the user may be granted access to the content based on a comparison of the provided authorization code and a second authorization code transmitted with the electronic content, and transmission of the second authorization code may be controlled by a content provider to control access by the user.
