Securing the delivery of digital content over the Internet

This paper looks at the security issues that arise for the browsing, selection and delivery of digital content over the Internet. Particular emphasis is placed on the problems of finding security solutions for microtransactions (small items of content) and micropayments (low-value content), and the digital rights management issues concerning the protection of content after it has been delivered to consumers. The paper concludes with a description of the secure content delivery system developed during the SIBIS project, which addresses many of the issues raised.
