H5 Fraud Protection

Loads the SDK → um.init() → waits the required interval → getToken() → sends the token to the server, which calls ExecuteRequestSG. For camera-based tags, open the webcam below before running the check.

1. Load SDK—
2. Initialize (um.init)—
3. Interval wait—
4. Acquire deviceToken—
5. Server ExecuteRequestSG—

Browsers hide camera device labels until you grant permission — so a virtual camera (OBS, ManyCam, …) is invisible to both this heuristic and the fingerprint SDK until the webcam is opened. Open it, keep it running, then run the device check so the SDK can collect camera signals.

Measures end-to-end evaluation latency. By default it reuses one device token (tokens are valid 7 days) and benchmarks the server decision path; tick “fresh token” to include SDK token acquisition each iteration.
