True Presence

Inspiration

Physical keys get lost, shared, and copied. We wanted a true presence-based access system that works 100% offline without cloud dependency. Inspired by Ring's mission of safer neighborhoods, we built a face-based unlock system.

We built entire project with Kiro Crew:

• Kiro generated offline-first architecture
• Kiro wrote ring_service.py and main.py with best practices
  
• Used Vibe coding + Spec-driven development

What it does

TruePresence is a Ring-powered access control system:

• Webcam acts as Ring camera simulator
• Detects motion -> Captures face -> Verifies offline with dlib in <1 sec
• If known user -> Calls Ring API to unlock door
• 100% Offline, No proxy, No cloud needed
• Live Demo: https://komalsaha8.github.io/True-Presence/

How we built it

• Ring Track: Created RingAccessController in ring_service.py - simulates Ring motion events and unlock() API calls as per hackathon rules (no physical device needed)
• Core: main.py uses OpenCV for camera, dlib face_recognition for matching, encrypts templates
• Frontend: index.html hosted on GitHub Pages for demo
• Built with Kiro: Used Kiro IDE for scaffolding and best practices
• Open Source: MIT Licensed, public repo with 5 Amazon collaborators added

Challenges we ran into

• Making face verification work under 1 sec offline without internet
• No physical Ring device - so we had to build proper simulator that still calls Ring API in code to satisfy judge requirement
• GitHub Pages deployment and making demo video under 3 min

Accomplishments that we're proud of

• <1s verification, fully offline - no cloud failure
• Satisfies all Ring track requirements: code calls Ring API, simulator works, open source with license, 5 collaborators added
• Live demo website in 2 mins

What we learned

• How Ring's ecosystem can be extended for access control without hardware
• Offline-first architecture is critical for security systems
• Kiro's spec-driven dev speeds up hackathon builds

What's next for True Presence

• Integrate AWS S3 for encrypted backup of face templates
• Add Amazon Bedrock for anomaly detection
• Support actual Ring devices + Alexa+ voice unlock
• Mobile app
