# FuzzyPSI-hamming: Deployment-Oriented FPSI Demo

This Hugging Face Space presents **FuzzyPSI-hamming** as a reviewer-facing, deployment-oriented demo for privacy-preserving fuzzy private set intersection over Hamming distance.

## What this Space demonstrates

- **Image-driven query workflow** for a public demo frontend
- **Binary-code matching** derived from the Hamming-FPSI pipeline
- **E-LSH candidate generation + exact verification story** exposed in a product-style interface
- **Protocol metrics panels** showing threshold, communication, latency, and Gao-feasibility information
- **Dual backend modes**:
  - **Simulation mode** for robust public interaction
  - **Optional full protocol mode** when native FPSI binaries are configured

## Reviewer-facing positioning

This Space is designed to show the engineering effort beyond the paper artifact:

1. turning the protocol into an interactive web application;
2. bridging uploaded images to binary-code matching;
3. exposing system metrics and deployment status in a usable UI;
4. organizing the project as an isolated Hugging Face deployment target.

The current public release is **image-first**. The code layout also includes a path for short-video analysis, but the first deployment focuses on making the image path reliable.

## Demo data policy

The public demo uses a **fixed LFW-derived gallery** so reviewers can test the system in a stable and reproducible way. The deployment project is intentionally isolated from the main research artifact repository.

## Notes

- The protocol core is adapted into this Space as a separate deployment project.
- Public demo mode prioritizes reliability and reviewer usability.
- Full native protocol execution is exposed only when the deployment environment is provisioned for it.
