Abstract
A secure flexible plugin architecture allows plugins to dynamically interconnect in highly flexible arrangements to permit the handling of many kinds of file formats. Interconnection is self-administered through a supervised volunteer system. In a media player example, the system is capable of handling files with multiple layers of formatting such as encryption, compression, etc. The resource selection is completely transparent and a user need not be concerned about the packaging of resource files. A security mechanism that is enforced at the level of the plugins is also provided. Plugins can opt in or out depending on the other components in the dynamically generated chain of plugins used to filter or convert a file.
