Is there a way to determine if a wma file is DRM'd? I'd like to be able to do this in a trusted, out of browser Silverlight 4 application so pinvoke isn't an option. I supposed I could just try to play the file in a MediaElement but that doesn't seem efficient. ...
Suppose you have a .wma / .wmv file and you want to detect: is it DRM protected ? (then hopefully) details of the DRM protection (like when does the license expire etc.)? Is there a C# / C++ api for it? It seems that Windows Media Player can do it - if you click properties on that file... but Explorer does not show this info. Note:...

I am using WM DRM to protect content. Licenses for the content are issued through a web page (lauched from within Windows Media Player) using an embedded active-X control with the following Id. clsid:A9FC132B-096D-460B-B7D5-1DB0FAE0C062 Obviously, not everyone has access/permission to install the Active-X control so there is a separa...
I've been tasked with securing video content for an intranet client/server solution. There seams to be a couple of DRM solutions out there, but most of them have various draw backs for us. Cost is a huge factor. Maintaining the "keep honest people honest" philosophy, I was asked if it would be possible to obfuscate the files on the se...

My company runs a video website. We currently make our content available via streaming, and download to Windows PCs with WMRM DRM. We're looking to make content available to download for Macs but would need to protect them with the FairPlay DRM system.

I was thinking about this earlier and figured I'd ask. If I made an application that has lots of resources, what would stop someone from extracting and adding/modifying the resources I ship with it? Does an application that doesn't want its data manipulated have any sort of option to protect itself? ...
I'm working on an application that requires support for forward locking of media files on Android (1.6 and above). Of course, there appears to be no documentation in the APIs on how this might work. The two questions I have are firstly whether forward locking is supported on Android (and in which versions of the platform) and secondly h...

The company I work for has a download manager in place that handles distribution, DRM, installation of our products - when a user gets them off our website. However, we're using an clunky system for packaging and protecting our products when we do press releases or make retail CDs. Part of the antiquation problem is the fact that the a...
I am writing an ebook reader that supports the epub format (i have the parsing of open epub working), but I would like to support the reading of Adobe DRM locked epubs.

Since Flash is losing ground I would like to know if there are ways to protect html5 videos with DRM (H264, .ogg and WebM). Update Found out that safari supports HTML5 drm hinting with .mov files. Which stops users from directly saving the files. Still leaves all other browsers. http://www.apple.com/html5/showcase/video/ ...
The Sony Playstation 3's in-built DRM/Copy Protections makes it a very attractive platform for developers (less piracy) same perhaps with iPhone. I believe this is achieved by virtualising the OS, sandboxing the applications. Can we have that security on Windows? are their any plans or means? ...
