How Sootru Works

Simple. Reliable. No technical knowledge needed.

1
🔐

SIGN

Take a photo or video using the Sootru app. It is cryptographically signed using your device's secure hardware; a unique seal that can never be faked.

2
₿

ANCHOR

The signature is anchored on the Bitcoin blockchain, creating a permanent timestamp that no one can alter.

3
✅

VERIFY

Anyone can check whether the media is genuine and unedited, even after it has been shared and compressed on social media.

Two Layers of Verification

Scan. Verify. Trust.

Every Sootru capture includes an embedded QR code that lets anyone check its authenticity; instantly from a scan, or in full detail through the app.

📷
SCAN QR CODE

Preliminary Verification

Scan the QR code on any Sootru media to instantly confirm it was captured with the app. You'll see:

  • ✅Confirmation it was captured with Sootru
  • 📅Exact date and time of capture
  • 📍GPS location (if enabled by creator)
  • 🎥Media type (photo or video)
Note: A QR code confirms a capture was recorded with Sootru, but the code could have been copied onto different media. For complete tamper verification, use full verification in the app.
Works with any QR scanner app or camera. No Sootru app needed.
🛡
IN THE APP

Full Verification

Open the Sootru app's verification tab to confirm media hasn't been edited, cropped, or tampered with in any way:

  • 🔍Detects any edits, crops, or modifications
  • ✅Works even after social media compression
  • 🔗Verify from social media links (TikTok, Instagram, X)
  • 📂Upload the original file for instant analysis
Important: Screenshots cannot be verified. Only original files or direct links to the post will work.
All verification runs on-device. No file uploads.
