I built ProofFace a visual provenance & content verification engine in Rust I have been building ProofFace an end-to-end visual provenance and content verification engine built in Rust.

The idea is simple:

Finding an image online doesn’t prove that it’s authentic, original, or unchanged.

So I built a verification pipeline that goes from:

📸 Image input → 🧠 Neural face detection → 🔎 Web visual discovery → 🧬 Biometric similarity → 🔐 Deterministic SHA-256 fingerprinting → ⛓️ Polygon Amoy blockchain proof → ✅ Verification result

Some of the things I worked on:

• ONNX-based face detection • 128-dimensional biometric embeddings • Presentation attack detection • Parallel visual candidate evaluation • Cosine similarity matching • RFC 8785 JSON canonicalization • SHA-256 content fingerprinting • Polygon smart-contract integration • Automated unit & integration testing

The project currently has 30 passing tests.

What I enjoyed most was bringing several different areas together computer vision, Rust systems programming, cryptography, and blockchain into one reproducible verification workflow.

Would love to hear what you’d improve or add to a system like this.
