Obfuscated / Tokenized content security

Detlif — Tue, 20 Oct 2009 12:21:23 GMT

Hi everybody out there

I am looking for a way to prevent that our streaming video content is accessed from other players/clients than ours (wmp/silverlight).
We are also starting up with smooth streaming. So that must also be protected againt hotlink/deep linking.

At this point we are using an application on the streaming servers that validates a tokenized url before serving the stream to the requester. But that application does not work on ws8 / iis7.

I can see that there are some obfuscating feature in the playlist module, that maybe could provide some of this protection. But as I read it that only secures that the content is played in the order specified in the playlist. And what we would need is a way to ensure that we only allow the content to be viewed in our players by validated users.

Is there any way to do this or do we still ned a 3. party application installed on the servers?

Hi, MrUrb,

Were you able to resolve this? If not, have you tried using Failed Request Tracing to isolate the source of the error? The easiest way to do this is as follows, assuming you have not yet installed the Tracing option:

Go to www.microsoft.com/web
Install Web Platform Installer (WebPI)
Install (Failed Request) Tracing

Click on the WebPI "Web Platform" tab
Under Web Server, click on Customize
Under Health and Diagnostics, check the Tracking checkbox
Install

Follow the 404 Tracing instructions in http://blogs.iis.net/webtopics/archive/2009/06/12/troubleshooting-a-simple-error-message-using-freb.aspx.

Hi Vishal. I am the administrator of an Internet only Station. The streaming is based on Windows Media Services and SSPL that are combining recorded videos and Live broadcasts. A common scenario using the WMS. But... we want to get rid of the Embedded Media Player and replace it with Silverlight and Media Element. The reason is the compatibility issues with browsers other that IE. Properties like Controls.currentAudioLanguageIndex (we are also multilingual) are only exposed if Media Player is embedded as ActiveX object that can be done without plugins only on IE. The next problem is that if we use Silverlight with our current configuration the use of MBR streaming should be dropped because it is not honored in Silverlight. The next problem is that Smooth Streaming files, that is the future, can only be streamed from IIS with Media Services but now simulated live scenario like the one needed for an Internet only station cannot be used if Web Playlists don't have wall-clock functionality... So as it seems we are stack with WMS SSPL, MBR files and many select case blocks to make use of as many browsers as we can. I would appreciate if you have any thoughts.

Hi Stavros. Wall-clock is not currently supported in Web Playlists and there is no plan for the same yet. Could you please share the scenario you plan to use it with and then we can take your feedback right into are feature prioritization.

Hi,

I've tried today the web playlists functionality of IIS Media Services 3.0 Beta. Unfortunately I didn't found anything that can be used instead of the simulated live functionality of server side playlists of Windows Media Services, like wallclock. Am I missing something? Is it something that will be added in the release version?

Hi, Galgamesh,

Yes, Web Playlists automatically obfuscate the URLs in each playlist. By default, each user gets personalized URLs to the original media, and Web Playlists enforces that only the original requester can play those URLs.

For example, an entry in a typical Windows Media playlist (ASX file) might look like this:

In the playlist delivered by Web Playlists, the non-sharable tokenized entry would look like this:

If you choose to Disable Skip on your Web Playlists entries, you can also enforce a predetermined playback sequence.

Would this work for you?

Hi Mathi

There is a lot of documentation on Web Playlists and WMS SSPL. However, there is hardly anything differentiating the two. I will try to produce a blog post shortly.

Meanwhile, Web Playlists would work well for you scenario (assuming you don't conventional streaming). Here is a set of links that will help you get started. I will happy to answer any more questions:

Hi Vishal,

1. No, the advertisements cannot be skipped.

2. The advertisements are local.

We also want to log the statistics & authenticate the users.

How can one decide which platform to choose for their requirement. Anything published regarding this?
