💡 Inspiration
Law enforcement agencies today face a growing challenge — managing vast amounts of digital evidence from CCTV cameras, mobile phones, body cams, and online data. Often, this evidence is scattered, unsecured, or difficult to verify, leading to delays in justice and weakened cases. We were inspired to create EVIDEX to simplify and secure this process — empowering police and investigative agencies to handle digital evidence efficiently, transparently, and intelligently.
⚙️ What It Does
EVIDEX is a secure, AI-powered digital evidence and case management system that:
Collects and organizes digital evidence (photos, videos, documents, recordings, etc.) in one secure platform.
Tracks the chain of custody to ensure authenticity and prevent tampering.
Uses AI for smart tagging, categorization, and case linking.
Provides role-based access control for authorized officers.
Enables real-time collaboration between departments.
Generates automated reports and maintains audit trails for legal admissibility.
🛠️ How We Built It
We built EVIDEX using:
Frontend: React.js (for an interactive, responsive user interface)
Backend: Node.js with Express.js
Database: MongoDB for secure, scalable data storage
AI Integration: Python-based modules for automatic file tagging and facial/object recognition
Security: AES-256 encryption and blockchain-backed integrity verification
Cloud Integration: AWS for storage and role-based access management
UI/UX Design: Canva and Figma for clean, minimal, and intuitive design
🚧 Challenges We Ran Into
Integrating multiple data formats like video, images, and PDFs securely.
Maintaining end-to-end encryption while ensuring fast access.
Designing a scalable architecture to handle large evidence files.
Creating a user-friendly dashboard for officers with varying technical skills.
Ensuring data compliance and legal standards for digital evidence admissibility.
🏆 Accomplishments That We’re Proud Of
Successfully built a working prototype of a secure digital evidence system.
Implemented AI-based evidence tagging to speed up investigation workflows.
Created a blockchain verification module for evidence authenticity.
Designed a clean, modern interface that simplifies case tracking for officers.
Developed a solution that could realistically support law enforcement and judicial transparency.
