About this app

Protect your photos and videos with an invisible watermark, digital certificate, and Aruba legal timestamp
ShieldSnap certifies your photos and videos with professional encryption technology and an eIDAS-qualified legal timestamp. If someone uses your content without permission, you have digital evidence to take action with a DMCA request or legal action.
HOW IT WORKS
Take a photo or record a video, or choose a file from your gallery. The app applies invisible 3-layer DCT watermarks to the photo and calculates the SHA-256 hash of the video directly on your device—the video is never uploaded. A real-time selfie with the front-facing camera is embedded in the PDF certificate, linking your identity to the certified content. Each certificate is digitally signed with ECDSA and verifiable online.
PHOTO CERTIFICATION

Invisible 3-layer DCT watermarks (Anti-Deepfake, Anti-Scraping, Anti-Reposting)
8x redundancy with majority voting — resists compression, screenshots, resizing, and social media uploads
PDF certificate with ECDSA signature, GPS, date, and device

VIDEO CERTIFICATION

Locally calculated SHA-256 hash — the video stays on your phone
PDF certificate with ECDSA signature, metadata, and file fingerprint
Unique ID (SS-2026-V) for each certified video

IDENTITY SELFIE

Selfie taken in real time with the app's front-facing camera
Embedded in the PDF certificate — links your identity to the content
Certified content + a profile full of certified selfies = overwhelming proof of ownership
