About
Building the trust layer for digital content
AuthProof helps organizations create cryptographically verifiable proof records for digital content, register integrity fingerprints, build chain-of-custody audit trails, and publish verification certificates that third parties can independently inspect.
Our Mission
As digital content becomes easier to duplicate, modify, and generate at scale, organizations need reliable ways to prove what was submitted, when, and that it has not been altered since. AuthProof provides the infrastructure to create, store, and share those proof records.
We focus on cryptographic integrity, transparent proof scope, and honest communication about what our records confirm and what they do not. Optional duplicate-registration lookups provide informational advisories alongside hash-based integrity proof.
Built across core disciplines
AuthProof is built across cryptographic proof, security, infrastructure, and registry systems - all working together to deliver verifiable content proof at scale.
Cryptographic Proof Systems
SHA-256 integrity hashing, Ed25519 signing, tamper-evident report generation, and public verification certificates.
Security Engineering
Encrypted signing key management, secure upload pipelines, access control, and tamper-resistant evidence records.
Platform Infrastructure
Scalable architecture for high-volume proof generation, verification delivery, and global availability.
Registry & Analysis Systems
Optional duplicate-registration lookups that provide informational advisories alongside cryptographic proof.
