Abstract: Live stream piracy is a stealthy yet severe industry problem — your paid courses sold at $1.50 on resale platforms, your corporate training recorded by competitors, your live room illegally embedded on third-party websites for traffic. This article systematically introduces 4 lines of defense: URL authentication, access control, transport encryption, and DRM copyright protection — each with clear configuration guidance and use cases to build a complete security system from "preventing peeking" to "preventing screen recording."

Incident 1: An online education company invested ¥2 million in 50 premium courses. Two weeks after launch, screen recordings appeared on resale platforms at ¥9.9/set with 3,000+ buyers. Direct loss exceeded ¥500,000.
Incident 2: A tech company's product launch internal training was shared externally — competitors screen-recorded the entire session. Core product strategy and pricing leaked.
Incident 3: A popular host discovered their stream was embedded in illegal gambling sites for traffic generation, damaging personal brand and causing legal disputes.
If you're still "streaming naked" (no security), these incidents can happen to you anytime.
| Defense | Description |
|---|---|
| URL Authentication | Playback URL includes txSecret signature and expiration time |
| Referer Protection | Restricts playback to specified websites/apps only |
| IP Blacklist/Whitelist | Allow specific IP ranges only, or block known malicious IPs |
| Defense | Description |
|---|---|
| HTTPS Encryption | Full-chain SSL/TLS encryption preventing man-in-the-middle attacks |
| Certificate Management | One-click HTTPS certificate binding in console |
| Defense | Description |
|---|---|
| Remote Auth | Every playback request callbacks to your business server for secondary verification |
| Fine-grained Control | Enables "one person one code," "device binding," "view count limits" |
This is an exclusive capability of Tencent Cloud CSS — other major cloud platforms don't support it.
| DRM Protocol | Terminal Coverage | Tencent Cloud Support |
|---|---|---|
| Widevine | Android/Chrome/major browsers | Supported |
| Fairplay | iOS/Safari/Apple devices | Supported |
| NormalAES | Custom encryption scheme | Supported |
DRM is the "ultimate defense": Even if users screen-record, the captured content is encrypted (black screen or garbled) and cannot play normally.
Tencent Cloud is the only platform supporting all three DRM protocols simultaneously.
| Event Level | Scenario | Recommended Defense | Security Level |
|---|---|---|---|
| Basic | Free streams, brand awareness | URL auth + HTTPS | Medium |
| Standard | Corporate streams, regular paid content | + Referer + IP control | Medium-High |
| Advanced | Premium paid courses, corporate training | + Remote playback auth | High |
| Maximum | Copyright content, core trade secrets | + Triple DRM encryption | Highest |
| AI Feature | Description |
|---|---|
| Smart Content Review | AI auto-identifies violations |
| Audio/Visual Erasure | Auto-blur faces, license plates, and other private info |
| Quality Assessment | Quantified visual quality monitoring |
| Watermark Tracing | Embed invisible watermarks for post-piracy source tracking |
| Action | Contents | Cost |
|---|---|---|
| Basic Protection | URL auth + HTTPS + Referer protection | Free (built-in) |
| DRM Trial | 20GB free traffic + DRM testing | ¥0 |
| Complete Solution | Starter Combo (1TB + 100h Top Speed Codec) | ¥190 |
Security protection costs are far less than the losses from security incidents. A single piracy event can cost tens or hundreds of thousands, while enabling full security adds almost no additional expense.
