PayProof – UPI Payment Verification System

Project Overview

UPI payments are widely used, but fake payment screenshots and risky transactions are a common issue. Many users rely on screenshots without being able to verify whether a payment is genuine.

PayProof is a web‑based system that helps users:

• Verify the authenticity of UPI payment screenshots
• Assess the risk level of a UPI payment using basic transaction details

The project focuses on a practical, easy‑to‑use solution for improving UPI payment safety.

Key Features

• Screenshot authenticity check (Genuine / Suspicious / Likely Fake)
• OCR‑based text extraction and image quality analysis
• Payment risk analysis (Safe / Medium Risk / High Risk)
• Clear, explainable results for users
