Why Watermarking Isn't Enough

Watermarks only deter piracy. We actively prevent it. If they can't record, they can't leak.

The Shield

Multi-Layer Defense

We use kernel-level detection on Windows and native OS security flags on Mobile to ensure nothing captures your screen.

Core Tech

Heuristic Detection

We don't just look for filenames like "obs.exe". We analyze app behavior. If an app tries to hook into the display driver, we block it instantly.

  • Detects Unknown Recorders
  • Blocks Renamed Apps
  • Background Process Scan

Black Screen Layer

Even if a recorder bypasses detection, it records nothing. We use hardware overlay surfaces that screen recorders cannot capture.

  • OS-Level Protection
  • Works on Print Screen
  • Works on Sharing

Process Killing

Detected a recorder? Kill it. Our app automatically terminates prohibited applications like TeamViewer or AnyDesk during playback.

  • Auto-Terminate
  • User Notification
  • Whitelist Support

Screenshot Block

Disables the 'Print Screen' key on Windows and screenshot gestures on Android/iOS. Capturing yields a black image.

  • Disable Snipping Tool
  • Block Key Combinations
  • Mobile Secure Flag

Browser Protection

For web playback, we use Widevine DRM Level 1/3. This leverages the browser's built-in CDM to prevent recording extensions.

  • Widevine Integration
  • Block Extensions
  • Encrypted Stream

Mobile Shield

On Android, we use FLAG_SECURE. On iOS, we use UIScreen protection. This prevents any app (even system apps) from recording.

  • Prevents Mirroring
  • Prevents Casting
  • Prevents Screenshots
Active vs Passive

Don't Just Warn.
Block Them.

Watermarks are passive; they only identify the thief after the leak. Our Screen Capture Protection is active. It stops the theft from happening in the first place by interfering with the recording process itself.

Smart Detection

We Find Them.
Even the Hidden Ones.

Students try to be smart by renaming "OBS.exe" to "notepad.exe". Our software scans for the digital signature and behavior of the process, not just the name. We identify background recording services that run silently and shut them down.

Reliability

Secure & Stable

Blocking recorders shouldn't mean crashing user's PCs. Our tech is lightweight and accurate.

No False Positives

We whitelist essential system apps. Antivirus, drivers, and background services are never blocked.

Lightweight

Uses minimal CPU (<1%). It runs silently in the background without slowing down the student's device.

Works Offline

Detection logic is embedded in the app. It works perfectly even when the internet is disconnected.

Regular Updates

We constantly update our blacklist as new screen recording software is released in the market.

Technical FAQ

Protection Questions

How our blocking technology works.

Software alone cannot physically block a capture card, BUT we have HDCP Compliance. If the user's setup supports HDCP, our player enforces it, preventing capture cards from recording the stream.

#HDCP #Hardware

Yes. Our software includes Anti-VM technology. It detects if the player is running inside a Virtual Machine (VMware, VirtualBox) or Sandbox and refuses to play the video.

#AntiVM #SandboxBlock

The video player window will turn completely black for the remote viewers. The audio might also be muted depending on your settings. The student can see the video, but they cannot share it.

#BlackScreen #AntiShare

Yes. We scan the active process list for known signatures of recording software. Even if the recorder has no visible window, our heuristic engine will find and terminate it.

#BackgroundScan #Heuristics

No. We maintain a strict whitelist of system-critical applications and trusted software (Antivirus, Drivers). Only apps that interact with the screen buffer are targeted.

#Whitelist #Safe
