SPIN Tag Camera

About the Project
Project Overview
SPIN Tag Camera captures field photos and videos with coordinate, altitude, accuracy, address, timestamp, and on-device DigiPIN context. Media remains on-device; optional cloud upload is limited to audit metadata. SPINTag API and Admin Dashboard let operators review audits, devices, and users without a cloud photo gallery.
Problem Statement
Field surveys, inspections, and infrastructure documentation need location, time, and integrity context at the moment of capture. Typical cloud photo pipelines store full media on servers, while loose geotags are easy to spoof.
Solution
On-device location stamping with DigiPIN, optional integrity signatures, and metadata-only audit upload so evidence stays on the device.
Target Users
- Field survey teams
- Site inspectors
- Infrastructure documenters
- Compliance auditors
Key Features
GPS-Stamped Capture
Photos and video with coordinates, altitude, accuracy, address, and timestamp.
On-Device DigiPIN
Generates DigiPIN from GPS using the public DigiPIN specification.
Integrity & Audit
Hashes and Ed25519 signatures with metadata-only cloud audit.
Photo Map Gallery
In-app gallery and map with Esri / OpenStreetMap layers.
Value Proposition
Trusted field evidence with location, time, and DigiPIN at capture — without storing full media in the cloud.
