About this app

ShieldSnap certifies your photos and videos with professional encryption technology. If someone uses your content without permission, you have the digital evidence to take action with a DMCA request.
HOW IT WORKS
Take a photo or 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
• 3-layer invisible 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
• One certified content + a profile full of certified selfies = overwhelming proof of ownership
