Executive
Summary

Locating missing children and unidentified individuals across vast geographical regions traditionally involved manual flyer distribution, disjointed police logbooks, and weeks of administrative delay.

Travash built Darpan, an AI-powered biometric facial recognition platform that extracts high-dimensional facial embeddings from field photos and cross-matches them against historical police databases in seconds.

The Challenge

High noise, poor photo quality, and aging variations across historical photo records.

Field officers frequently capture photos under poor lighting, steep angles, or with low-resolution smartphone cameras. Matching these against archival photos required deep learning models resilient to age progression and illumination shifts.

KEY CHALLENGES:

Varying lighting conditions, image blur, and off-axis camera angles in field conditions
Age progression matching between childhood photos and adolescent records
Massive database size requiring sub-second vector search response times
Strict zero-trust security and data privacy safeguards for sensitive citizen data

When dealing with missing children, every second and every data point counts. Travash didn't just build an app; they engineered a massive, highly secure database powered by advanced AI and facial recognition. The way their system analyzes complex biometric patterns against thousands of records in real-time is extraordinary. Because of their robust data architecture, we have successfully identified and reunited over 70 children with their families. Travash’s technology is quite literally changing lives.

Why This Matters

Does Your Organization Face a Similar Operational Challenge?

THIS CASE STUDY IS RELEVANT FOR ORGANIZATIONS MANAGING:

  • •High-volume transactions slowing down customer or citizen service delivery
  • •Legacy databases unable to meet modern mobile and cloud scalability expectations
  • •Need for secure, compliant automation without disrupting existing daily operations
  • •Desire to harness AI and modern web engineering for measurable business ROI

It is to identify what can be automated, what should be flagged, and where human decision-making should remain in control.
