Why Bandhan? (User Psychology & Impact)
When people lose essential belongings—a passport, a child’s medical supplies, or a family member—the primary emotion is panic. Traditional help desks lead to long queues and fragmented records.
Bandhan restores calm through compassionate transparency:
- Community Trust: When people can see what is lost and found in real time, quiet kindness turns into immediate action.
- Ground Officer Empowerment: Gives crowd management teams and volunteers a simple, instant way to log reports, verify claims, and mark cases resolved.
- Instant Peace of Mind: Eliminates waiting games by using mathematical AI vector matching behind the scenes to link lost items with found reports in seconds.
How Bandhan Works (Simple 3-Step Flow)
- Direct Data Logging: Ground officers instantly log lost or found item details and photos onto a live, accessible open ledger network.
- Automatic AI Matching: Our AI engine converts descriptions into mathematical vector embeddings to automatically connect matching reports.
- Protected Return: To prevent false claims, officers ask targeted verification questions (e.g., “What is the registration or serial number?”). Once confirmed, the case status updated to Resolved.

CockroachDB Tools Used
1. CockroachDB Distributed Vector Indexing
- How It Was Used: Stores 1536-dimensional text and image embeddings directly in CockroachDB using the
VECTORcolumn type. - What the Agent Did: Executes native vector distance queries (
ORDER BY embedding <=> query_vector LIMIT 5) to instantly surface high-probability lost-and-found matches across thousands of records.
2. CockroachDB Cloud Managed MCP Server
- How It Was Used: Connected to
https://cockroachlabs.cloud/mcpusing read-only Bearer token credentials. - What the Agent Did: Allowed our AI development environment to inspect table schemas, review vector index health, and debug zero-match edge cases safely without touching production data.
AWS Services Used
1. AWS Cognito
- How It Was Used: Secures user identity management and role-based access control.
- What It Powered: Protected sensitive citizen reports while granting entry creation and verification powers to ground officers.
