The aim of strong digital rights management (DRM) is to enforce usage rules in end-user devices on behalf of content providers. Strong DRM is not well accepted by customers. Moreover, strong DRM is repeatedly circumvented and broken. Since Napster (and all its Peer-to-Peer follow-ups), the Internet is flooded with illegal digital content. We introduce the LWDRM technology as an alternative model. LWDRM relies on responsible behavior of customers. However, LWDRM contains a privacy problem, in that users sign media files which they wish to transfer freely from one place to the other. In this paper, we will explain the basic idea of the LWDRM technology and we will discuss the related privacy problem. We will show that there are methods to use LWDRM technology in compliance with privacy requirements of the users. A simple approach to harmonize LWDRM with privacy is separation-of-duty between certification authorities and content providers. Other, even more advanced models can be realized as well.
