What You Need to Run It on Windows

These are the exact minimum and recommended requirements published in the FaceLivenessDetection-Windows repository — check the repo directly for the latest version, since SDK requirements can change between releases.

Quick Start

Install and Activate

Install the SDK, then activate it with a license key before calling any liveness function – every platform follows this same activate-then-initialize pattern.

  • Clone the repo and download the CPU runtime into lib\cpu\.
  • pip install -r requirements.txt, then run run.bat to start the API on port 8084.
  • Copy your machine code from the terminal or GET /api/machinecode, then activate with POST /api/activate and your license key.
bash / python
# Activate with your license key
curl -s -X POST http://127.0.0.1:8084/api/activate ^
  -H "Content-Type: text/plain" ^
  --data-binary @license.txt

# Run a liveness check
curl -s -X POST http://127.0.0.1:8084/api/liveness ^
  -H "Content-Type: application/json" ^
  -d "{\"image\": \"<base64-jpeg>\"}"

:: Python bindings
:: ret = sdk.activate("license.txt")
:: ret = sdk.liveness(base64_image)
Licensing

How Licensing Works

Licenses are offline and bound to your machine. You don't need a license to start the API once, but liveness checks stay restricted until you activate with a key tied to your machine code.

FAQ

Frequently Asked Questions

Does the Windows SDK send biometric data to the cloud?

No. Every liveness check runs on your own server or directly on the device, depending on the platform – images never leave an environment you control.

How is the SDK licensed?

Licenses are offline and bound to a machine code, application ID, or bundle ID depending on the platform. Contact FacePlugin with that identifier to receive a license key – there are no per-call or per-check fees once licensed.

Where can I see the full source and open an issue?

The Windows integration is maintained publicly on GitHub at github.com/Faceplugin-ltd, where you can browse the code, file issues, and track releases.
