🛡️ VerifiX – AI-Powered Document Verification & Certificate Automation

VerifiX is a secure, AI-driven academic document platform that enables students, colleges, and third parties to verify, request, issue, and publicly validate academic certificates using Google AI, Firebase, and QR-based verification.

It eliminates fake certificates, manual delays, and opaque approvals by combining AI forensic analysis, human-in-the-loop approval, and tamper-proof digital certificates.

✨ Key Features

🔍 Document Originality Verification

• Upload existing academic documents (Bonafide, Transcript, NOC, etc.)
• AI-based forensic analysis using Gemini:
• Logical inconsistencies
• Date conflicts
• Formatting anomalies
• Suspicious textual patterns
• Generates Explainable Trust Score with reasons
• Admin review for high-risk documents

🏛️ Official Certificate Request

• Students can request new certificates from the college
• Supported certificate types:
• Bonafide
• NOC
• Transcript
• Fee Receipt
• Requests follow a AI → Admin approval workflow
• Students can delete requests before admin action

📄 Automated Certificate Generation

• Approved requests generate official certificates using:
• Prescribed college templates
• Student details
• Authority digital signature
• Unique QR code
• Certificates generated as tamper-proof PDFs

🔍 Public Verification via QR Code

• Each certificate contains a QR code
• QR scan opens a public verification page
• Displays: -- Certificate validity -- Student email -- Certificate type
• Purpose:Issuing authority & Verification engine

👨‍⚖️ Human-in-the-Loop Admin Workflow

• AI performs initial forensic analysis
• Admin reviews trust score and AI reasons
• Final approval or rejection by admin
• Full transparency in decision-making

👩‍🎓 Student Dashboard

• Two clear flows: -- Verify existing documents -- Request new certificates -- Track request status in real time -- Download approved certificates -- Verify issued certificates anytime

🧠 AI Processing Flow

• Student uploads document or submits certificate request
• Firestore trigger activates Cloud Function
• OCR extraction using Google Cloud Vision
• Gemini AI performs forensic analysis
• Trust score and reasons generated
• Admin approves or rejects
• Approved → certificate PDF generated with QR code
• Certificate becomes publicly verifiable
