Disable Downloading in my Asp.net webpage

Quote:

The only way to do this is with a trusted client, DRM and an encrypted source.

Your player opens up a connection, the user has a connection to the stream, you perform some magic authentication with their token and then transmite the encrypted data to them.

If you don't do this then anyone can download your video and save it out.

However with all that aside, someone can run screen capture, then save your video and do it again. This is again where the DRM comes in as one of the key features of the DRM in windows clients is that the buffer cannot be sniffed as it's on the protected media pathway.

I guess its a question of how to protect your revenue but dealing with pirates is always going to be a problem for software devs no matter what their business is.

Dear sam you ask too many different question. I will try to give some answer to what I know.

First you need to select the way you go to show your video. One popular way is the flash. YouTube use flash.

• So the tools that you can use is the one that convert the video to flash streaming file. There is all ready one from adobe. Other tools is video editing if this is what you asking for. Video editing with asp.net or with other programs like vegas video.

• How to not allow a user to download a video ?, you serve this video from an ashx handler, this handler just read the video file from a protected directory and send it to the video player. The id of the file that is going to play you send the id on the page header, or from inside redirect to that page to hide it as much as you can, but expert users can find it and download it at the end. How ever you can avoid the scanning of your page by a robot that try to download them all. All this is not that easy but not that hard also. This task is a full question and a tutorial alone, and as I say I think that is near impossible to avoid at the end the user not get your video if he won it to.

Other way to protect your video is to scramble the streaming header, and then on your flash player decode it again back. That way even if they get them ,they can not play it anywhere.

• About the streaming, adobe give a streaming server http://www.adobe.com/products/flashmediaserver/ but for small video files the flash player combinate with the flash video file can do almost the same work.

• flash video player, I think that there are some if you google it, one of them is the flowplayer http://flowplayer.org/

You need to know to programming also flash and probably make communication with the video flash and your pages using Javascript, and modify the player to your needs. All of that its not an easy task, but there are many resources and tutorial that can help you.

So start with the flash video on google.
