⚠️ A New Risk in the Age of Generative AI
In 3 Years, Can You Prove
That Video Is "Real"?
With generative AI, videos, audio, and images can now be easily faked.
When asked in court "That could be AI-generated, right?" — can you prove otherwise?

The "Trust Collapse" of Digital Evidence Has Begun
Worried About Video Tampering
Digital files can be easily edited, requiring a way to verify whether received videos remain "original" or have been modified.
Need to Prove Evidence Reliability
When submitting videos as evidence in court or audits, you need a system to prove to third parties "when, who, and how" it was recorded.
Cannot Track Edit History
Unable to maintain history of changes from original to edited versions, lacking transparent evidence management.
AI-VideoAuth Solves These Problems
Tamper Detection with Cryptographic Hashing
SHA-256 hash instantly detects even a single bit change in the video. Provides mathematically tamper-proof verification.
Complete Edit History Tracking
Record all generations from original to edited versions with hash chains. Achieve blockchain-style tamper-evident history management.
Third-Party Verification
Public verification API allows even non-registered third parties to verify authenticity with UUID and video file.
How Your Industry Can Use It
For Media & Journalists
- Record authenticity of footage at time of registration
- Verify integrity of videos received from sources
- Transparently manage pre-edit and post-edit history
"Being able to prove to third parties that field footage hasn't been tampered with directly enhances journalistic credibility"
For Legal Professionals
- Preserve dashcam and surveillance evidence
- Issue tamper detection certificates for court submission
- Maintain chain of custody records
"Being able to cryptographically prove digital evidence integrity is essential in modern litigation"
For Corporate Compliance
- Guarantee integrity of factory and retail surveillance footage
- Evidence management for internal audits and incident investigations
- Prevent tampering of quality control records
"Being able to prove workplace accident footage remains as registered is crucial from a corporate defense perspective"
Simple 3-Step Process
Upload Video
Register important videos in the system. Record the state at registration with SHA-256 hash.
Auto Hash Generation
Automatically calculate cryptographic hash. When registering edited versions, relationships with parent videos are also recorded.
Verify & Issue Certificate
Later verify integrity by comparing the same video. Download PDF certificate or issue public verification URL.

Technical Details (For Experts)
How it works: Hash Chain × Edit History Tracking × Third-Party Verification
1. Video Registration
When you upload a critical video, we compute a SHA-256 hash, assign a UUID, and store it together with core metadata in a secure registry.
2. AI Assessment Recording (Reference)
A dedicated AI model estimates whether the video is real, AI-generated, or unknown, and stores the label and confidence score as reference information. ※This is auxiliary information; the primary value lies in hash-based integrity verification.
3. Edit-History Hash Chain Integrity
When you register an edited version as a child of an original, each generation forms a new block linked to the previous hash, creating an edit-history chain that is tamper-evident.
4. Verification Against Registered Record
Later, you can upload any local copy; we compare its hash against the registry and report whether it is an exact match, different, or another generation in the chain.
Key Use Cases
- News agencies and broadcasters proving integrity of field footage
- Preserving and detecting tampering in surveillance or dashcam evidence
- Managing video evidence for compliance investigations and whistleblowing
- Ensuring originality of e-learning and training materials
- Guaranteeing quality and traceability of video datasets for AI training
Patent Information
Core parts of the system are patent-pending in Japan and via PCT as an "AI-based video originality proof system using generation detection and edit-history hash chains."
