# Mathematical Fallback Watermarking

> Frequency-domain mathematical embedding with high error correction.

When neural watermarking models are bypassed or unavailable, the processing engine automatically invokes a resilient mathematical fallback embedding pipeline.

## Frequency-Domain Embedding & Error Correction

* **Luminance Block Encoding:** Embeds forensic identification markers across discrete frequency coefficients.
* **Forward Error Correction (FEC):** Employs high-capacity Reed-Solomon algebraic coding to recover the watermark payload across burst noise, bit flips, social re-encoding, and spatial distortion.
* **Resilience:** Designed to maintain forensic traceability even under aggressive video compression and resolution downsampling.
