ShieldSnap Certifica - Foto

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.

VIDEO CERTIFICATION

Locally calculated SHA-256 hash — the video stays on your phone

Unique ID (SS-2026-V) for each certified video

IDENTITY SELFIE

Embedded in the PDF certificate — links your identity to the content
