TOKYO, Japan - s4story -- PIJ Inc. (CEO: Hiroshi Nakagawa) today announced the official release of AI-VideoAuth, the world's first* video authenticity verification platform that guarantees long-term reproducibility without relying on AI model behavior.

A New Verification Architecture Free from AI Instability

Most "authenticity" solutions depend on AI or deepfake classifiers, whose outputs naturally change as models evolve.
AI-VideoAuth solves this by implementing a deterministic, cryptographic, AI-independent chain, consisting of:

• SHA-256 block hashing
• Deterministic frame-level metadata
• An independent chain structure isolated from AI inference

Technical Highlights

■ World's First Deterministic Frame-Chain Structure*
"If the same video is uploaded—even 10 years later—the result will always be identical."
This architecture ensures true reproducibility, unlike AI-based classifiers.

AI Analysis Provided Only as Optional Reference

AI-VideoAuth offers deepfake/edit detection AI, but:

• AI scores do not affect authenticity
• AI output is not stored in the chain
• AI exists only as supplementary information

Embeddable Authenticity Badge

Notes on "World's First" Claim

The term refers specifically to the combination of:

• SHA-256 hashing
• Deterministic frame metadata
• Independent chain structure
• Full separation from AI-based judgments

This statement is compliant with international advertising guidelines.

*According to our research: a system combining cryptographic hashing + deterministic frame metadata + an independent chain structure fully separated from AI judgments.
