Having trouble pirating Flash video streams? Want to know how Adobe is doing DRM in Flash? I recently came across Christopher Levy's worthwhile article in Streaming Media from last December. Levy tells all, so to speak. Among his points are:
...Adobe rolled out several upgrades to its Flash Media Server 2 that are DRM-like and provide greater security for Flash Video objects. If you are providing Flash content as a progressive download, users can record the content from the cache in their web browser using a “ripper.” However, streaming the content using the proprietary Adobe Real Time Messaging Protocol (RTMP) results in increased protection from rippers. From Adobe’s website: “By default, content delivered by Flash Media Server is wrapped inside an Adobe protocol called RTMP. Because this is an unpublished, proprietary format, none of the RTSP stream ripping programs have the capability to rip media delivered over Flash Media Server.” Adobe also supports simple domain and IP authentication schemas as well as SSL to further enhance the security of Flash content.
