Title: System and method for supporting digital rights management in an enhanced Java.TM. 2 runtime environment

Abstract: A digital rights management (DRM) system and methodology for a Java client implementing a Java Runtime Environment (JRE). The JRE comprises a Java Virtual Machine (JVM) and Java runtime libraries components and is capable of executing a player application for presenting content that can be presented through a Java program (e.g., a Java application, applet, servlet, bean, etc.) and downloaded from a content server to the client. The DRM system includes an acquisition component for receiving downloaded protected contents; and a dynamic rights management layer located between the JRE and player application for receiving requests to view or play downloaded protected contents from the player, and, in response to each request, determining the rights associated with protected content and enabling viewing or playing of the protected contents via the player application if permitted according to the rights. By providing a DRM-enabled Java runtime, which does not affect the way non-DRM-related programs work, DRM content providers will not require the installation of customized players. By securing the runtime, every Java.TM. player automatically and transparently becomes a DRM-enabled player.
