The Problem
Deepfake technology enables fabrication of video and audio evidence, eroding trust in digital media. Centralized verification authorities are single points of failure.
The Solution
Pin Point runs ML filtering on-device before capturing, stamps each piece of media with GPS data, and anchors the hash to the Solana blockchain for trustless, immutable verification.
01
On-Device ML Authenticity Filter
Detects manipulation artifacts before capture, preventing tampered media from entering the pipeline.
02
GPS Cryptographic Anchoring
Media is bound to precise GPS coordinates and timestamp before Solana submission.
03
Immutable On-Chain Record
Solana ledger stores the evidence hash with no central authority required.
04
Instant Public Verification
Any viewer can verify authenticity in real-time via the public Solana explorer.
