Authenticity as a Law of Nature
Lightmark embeds an invisible, unforgeable optical signature into video at the moment of capture. Authenticate any video in under a second using Lightmark's real-time computer vision technology.

The Lightmark verifier decodes a live PWM beacon in a camera feed or uploaded video — sweeping 2–20 Hz and reporting the exact carrier the light is running at. Everything runs in the browser; no clip ever leaves the device.
Run a beacon
Open the beacon on any screen — it drives an LED (or the screen itself) as a Lightmark PWM emitter.
Point the verifier
Aim a camera or drop a clip into the live verifier. No upload, no recording — it reads the physical layer directly.
Lock in under a second
A Goertzel sweep auto-locks the carrier and lights up exactly the pixels carrying the signature.
The Technology Behind Lightmark
A revolutionary approach to video authentication that makes truth verifiable and deception impossible
Lightmark Optical Signature
Lightmark embeds an invisible, unforgeable optical signature at the moment of capture, impossible to replicate or remove.
Sub-Second Verification
Lightmark authenticates videos in under one second using real-time computer vision to decode optical signatures.
Cryptographic Security
Each Lightmark signature is cryptographically bound to the original video content, ensuring tamper-evident verification.
Lightmark CV Engine
Proprietary computer vision models decode Lightmark signatures with 99.9% accuracy across all video formats.
Multi-Frame Analysis
Lightmark verifies signatures across multiple frames, ensuring robustness against partial video manipulation.
Temporal Validation
Lightmark timestamps confirm the exact moment of capture, cryptographically proving when the video was created.

How It Works
From capture to verification in three simple steps
Capture with Lightmark
When video is recorded using Lightmark-enabled devices, an invisible Lightmark optical signature is embedded into every frame at the moment of capture.
Upload for Verification
Upload any video to the Lightmark platform. The system accepts all common formats and begins processing immediately.
Instant Results
The Lightmark CV engine scans each frame, detecting and decoding the embedded optical signature patterns. Within one second, receive a complete authenticity report with confidence scores, integrity metrics, and temporal validation.
