The Workflow User pays on clients website and redirects to a watch page on the Client's website.
User clicks a "Watch Video" button.
The button triggers an API call to Our Main Website.
Our backend saves the user's ID/Email to our database, requests an embed link from UIshare, and returns it to the client's frontend.
The Problem If our backend returns a standard, static URL, users can inspect the page source, copy the video link, and share it with unauthorized people who can then watch it for free.
What I Need Help With How do I implement a secure architecture to prevent this? Specifically:
Short-Lived Signed URLs: How to generate an embed link that expires in 30 seconds (preventing sharing), but allows the video to keep playing uninterrupted for the legitimate user once started?
IP/Domain Binding: How to restrict the video player so it only plays if accessed from the buyer's IP address and our approved domain?
Concurrent Session Blocks: Best practices for tracking active streams on our backend to stop a user from opening the video in multiple tabs or devices simultaneously.
Don't build this from scratch on top of a basic file host. If UIshare doesn't support signed HLS or DRM natively, you are fighting a losing battle. Look into Bunny Stream (Bunny.net), Mux, or VdoCipher. They handle the DRM (Widevine/FairPlay), HLS encryption, and signed URLs out of the box via simple API SDKs. Re-inventing a bulletproof video security architecture will cost you way more in dev hours and leaked revenue than a managed service ever will.
