Is there any way I can protect my flv files from download/hotlinking? Is there a special flash player I can use? Im using clipshare as the video software, and I have a dedicated server, with root access. Im thinking something like this: # Hide your FLV content behind a simple, custom one-time authentication mechanism * Player requests authorization key for content A * Server returns an authorization1 key: SHA1(content key + salt1) * Server stores content key, authorization1 key, authorization2 key (which is SHA1(authorization1 + salt2)) 1 one time use 2 limited validity (E.g.: 2 seconds) * Player creates authorization2 * Player requests content a with authorization2 * Server sends ´FLV´ content to client if and only if 1 authorization key matches to content key in server side store 2 authorization key has not expired Please help.
