DAPI-PUB Use Cases: Real-World Examples of Identity and Content Verification
DAPI-PUB is a public certification system that allows you to verifiably link a digital identity to original content, trademarks, projects, and online publications. It’s not a social network or publishing platform, but a public registry of verified identities and certified content.
This page showcases 13 real-world examples of how professionals, creators, associations, and public figures use DAPI-PUB to protect their digital identity and content against cloning, deepfakes, theft, and impersonation.
Why DAPI-PUB Is Different
✓ Manual Verification
Not automated. Each identity is manually controlled through a verification and document review procedure.
✓ Legal Value
Designed for legal contexts with cryptographic hashes, eIDAS-qualified timestamps, and expert digital signature.
✓ Identity + Content
Integrated certification: identity is cryptographically linked to specific published content.
✓ Public Verification
Anyone can verify instantly via QR code and public registry, without involving DAPI.
