🕵️‍♂️ UFDR AI — Unified Forensic Data Retrieval and Analysis Assistant

🎯 Overview

UFDR AI is an advanced AI-powered forensic intelligence system designed to revolutionize digital investigations by automating the analysis of Unified Forensic Data Reports (UFDRs). Built for law enforcement, intelligence agencies, and forensic laboratories, it transforms unstructured UFDR data into actionable, explainable, and court-ready insights — reducing analysis time from days to minutes.

🚀 Key Features

🔍 Intelligent Data Processing

• Multi-Format Ingestion: Supports UFDRs from Cellebrite, Magnet AXIOM, Oxygen, XRY, and custom exports (JSON, XML, SQLite, PCAP, Text)
• OCR & Artifact Extraction: Uses Tesseract to extract text from screenshots and image attachments
• Canonical Normalization: Converts vendor-specific formats into a unified forensic schema
• Hybrid Search: Combines keyword-based (BM25) and semantic (embedding-based) search for higher precision

🧠 AI-Powered Intelligence

• Natural Language Queries: Ask questions like "Show all chats containing cryptocurrency addresses shared with foreign numbers last month."
• Provenance-First RAG: Every answer includes exact file name, line number, and confidence score
• Entity Extraction: Detects phone numbers, IPs, crypto addresses, device IDs, and user references
• Temporal Knowledge Graph: Explore evolving relationships across people, devices, and communication events

📊 Analytical Tools

• Timeline Visualization: Chronological view of messages, calls, and events
• Interactive Graphs: Relationship mapping using NetworkX and Plotly
• Anomaly Detection: Flags irregular patterns such as sudden message bursts or new device appearances
• Risk Scoring: Assigns explainable suspicion scores to events

📄 Reporting & Evidence Management

• One-Click Report Generation: Exports findings to PDF or CSV with metadata and confidence levels
• Executive Summaries: Automatically generated concise overviews for case files
• Chain of Custody: Preserves audit trail and source citations for legal admissibility

🎨 Innovation & Uniqueness

🔐 1. Provenance-First RAG

Every AI-generated summary includes verifiable evidence citations:

"This address was identified in UFDR_20250710_chatdump.json,
lines 213–226, confidence: 0.92."

⏱️ 2. Temporal Knowledge Graph

Visualizes time-aware relationships between suspects, devices, and events:

• Detect when new numbers or wallets appear
• Track communication evolution
• Link devices across investigations

🧭 3. Smart Investigative Playbooks

Provides context-aware suggestions to guide analysts:

• "Correlate with call detail records"
• "Extract IMSI/IMEI linkage"
• "Check entity occurrence across UFDRs"

🧬 4. Domain-Tuned Forensic Models

Custom entity models trained for forensic contexts — capable of recognizing:

• Crypto addresses
• Device identifiers (IMEI, IMSI)
• Tool-specific forensic metadata
