Inspiration

Traditional mobile vaults and secure note managers rely entirely on passive encryption: data sits idle in storage while brute-force or key-tampering attacks happen in the background. We built Omen Vault with the AI Omen Oracle to transform personal storage from a passive target into an active, autonomous cyber-defense system that evaluates threat telemetry and takes immediate defensive action.

What it does

• Autonomous Threat Evaluation: Analyzes real-time telemetry anomalies (e.g., rapid unauthorized decryption bursts, cryptographic signature tampering).
• Multi-Turn Function Calling: Powered by Gemini 2.0 Flash, the agent autonomously executes specialized defensive tools:
  • inspectVaultIntegrity: Verifies cryptographic checksums and calculates risk scores.
  • isolateCompromisedNode: Quarantines compromised keys, isolates the node, and revokes active sessions.
  • logSecurityEvent: Commits immutable incident records to the audit ledger.
• Biometric Edge Gate: Local hardware biometric authentication gating all vault entries.
• Isolated Cloud Persistence: User-isolated Firebase Cloud Storage rules ensuring zero cross-tenant access.

How we built it

• Framework: Flutter & Dart for cross-platform edge performance.
• AI & Agent Architecture: Google Generative AI SDK (google_generative_ai) integrated with gemini-2.0-flash for high-throughput, low-latency autonomous tool calling.
• Cloud & Auth: Firebase Authentication, Cloud Firestore, and Cloud Storage.
• Monetization: RevenueCat Firebase Extension for subscription entitlement gating.
• Mobile-First Pipeline: Built, tested, and committed 100% on mobile using GitHub Codespaces.

Challenges we ran into

• Implementing deterministic multi-turn tool calling on mobile without blocking the UI thread.
• Balancing edge-first local encryption with cloud-backed anomaly stream processing.

Accomplishments that we're proud of

• Creating a fully working autonomous cybersecurity agent loop using Gemini 2.0 Flash function calling directly inside a Flutter client.
• Executing the entire development and deployment pipeline entirely on mobile.

What we learned

• How to structure deterministic function declarations and tool schemas with the Gemini 2.0 API.
• How agentic loops elevate standard apps into proactive autonomous assistants.

What's next for Omen Vault

• Distributed multi-node peer verification across local networks.
• Deploying Omen Vault as a foundational cybersecurity learning tool for youth technology initiatives at the Bennett World Youth Center in Panama.
