VoiceSeal is the voice provenance infrastructure layer — built for the era where AI voice platforms must prove consent, not just claim it.
The EU AI Act's Article 50 enforces August 2, 2026. The Code of Practice on Transparency of AI-Generated Content explicitly contemplates "providers specialised in transparency marking techniques" as third-party implementation partners. That is our category, and everything below is live in production:
→ Pre-synthesis consent gate (patent pending) — the only API in market that verifies biometric identity, active consent, and license scope before audio is generated. Approval token or hard block, in real time.
→ Biometric voice registry — 256-dimensional voice fingerprint per enrolled artist. One enrollment, permanent verifiable record.
→ Multilayered provenance — machine-readable RIFF/XMP metadata, LSB spread-spectrum watermarking, and cryptographically signed provenance certificates on every protected file.
→ Detection and enforcement — four-model detection stack scanning 10+ TTS platforms and major social platforms daily. Every alert ships with a fully prepared DMCA notice (all seven statutory elements under 17 U.S.C. § 512(c)(3)).
→ Tamper-evident audit trails — SHA-256 hash-chained logs, anchored daily to Bitcoin via OpenTimestamps. Independently verifiable without trusting our infrastructure.
For AI voice platforms: neutral third-party verification your compliance filings can cite. For voice artists: enrollment, protection, and a licensed marketplace where your voice earns on your terms.
Marking proves what content is. The consent gate proves the platform had the right to make it. VoiceSeal is the only closed loop.
