TrustCapture

TrustCapture is a field photo verification app for vendors and field workers. Every photo is GPS-stamped, sensor-validated, and cryptographically signed using your device's hardware security module — making it impossible to fake location, timestamp, or image authenticity.

BUILT FOR FIELD OPERATIONS
Whether you're verifying billboard installations, documenting deliveries, or conducting site inspections, TrustCapture ensures every photo is captured live, at the right place, at the right time.

HOW IT WORKS
1. Log in with your Vendor ID and OTP (first time only — subsequent logins use device key authentication, no SMS needed)
2. Select your assigned campaign
3. Capture photos — GPS, barometric pressure, magnetic field, and accelerometer data are collected automatically
4. Photos are signed with your device's hardware-backed key and uploaded securely

KEY FEATURES
• Forced live capture — gallery uploads blocked, every photo must be taken through the camera
• GPS geofence verification — photos captured outside the designated area are flagged
• Multi-sensor validation — barometric pressure, magnetic field, and hand tremor analysis
• Hardware-backed signatures — ECDSA keys stored in Android StrongBox/TEE, impossible to clone
• Visible watermarks — GPS coordinates, timestamp, and vendor ID burned into image pixels
• Offline-ready — photos stored in encrypted local database, auto-uploaded when connectivity returns
• Background sync — WorkManager handles uploads even when the app is closed
• Device key authentication — after first OTP login, sign in instantly with hardware key (no SMS costs)
• Battery optimized — adaptive GPS power modes reduce battery drain during extended field sessions

SECURITY
• End-to-end encryption for photo storage and transmission
• SQLCipher encrypted local database
• Certificate pinning for API communication
• No photo data stored on device after successful upload
• GDPR-compliant with privacy consent and data export options

REQUIREMENTS
• Android 7.0 (API 24) or higher
• Camera and GPS access required
• Internet connection for upload (offline capture supported)
• Vendor ID provided by your employer
