: Digital piracy is threatening the global multimedia content industry and blindly applied coercive Digital Right Management (DRM) policies do nothing but legitimizing this piracy. This paper presents a new software and hardware infrastructure aiming at reconciling the content providers’ and consumers’ point of views by giving the ability to develop fair business models (i.e., that preserve the interest of both parties). The solution is based on the use of tamper-resistant devices (smart cards) to store securely sensitive data (e.g., personal consumer data or data expressing the terms of a B2C contract or licence) and to perform the computation required by a contract/licence activation. In other words, smart cards can be seen as tamper-resistant Service Level Agreement (SLA) enablers.
