feat(hardware): add pHash to handle image compression
The current SHA256-based logic is a bit too "brittle"—even a tiny bit of compression during network transit breaks the entire ZK verification. To fix this, I’ve added Perceptual Hashing (pHash) support on the hardware side.
What I did:
imagehashandPillowto generate a visual fingerprint of the photo at capture time.PHASH_AVAILABLE) so the app doesn't crash if these libraries aren't installed.pHashinto the upload metadata.The Bigger Picture:
This is actually the first step for my GSoC 2026 proposal. My plan is to use this pHash inside a RISC Zero ZK circuit (using Rust) to calculate Hamming Distance. This way, the system can mathematically tolerate minor compression while still blocking AI-generated fakes.
This approach is inspired by my research on image forensics in the "Yuanjing" project. Excited to see this moving forward!
