When media can be faked,
prove yours is real.

Sootru signs every photo and video the instant you capture it, so anyone can confirm it is authentic and unaltered, even after it has been shared online.

Anyone can fake anything now.

Edited photos, AI deepfakes, and online scams mean seeing is no longer believing. When it matters that something is real, you need proof, not just your word.

How Sootru Works

Three steps, from the moment you capture to proof anyone can check.

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.

What You Can Prove

🛒

Buying & Selling

Prove an item is real and show its true condition before money changes hands, so no one can dispute what you sent or received.

📱

Creators

Prove your photos and videos are really yours and really happened, and sign your name into every capture so your audience knows it came from you.

📸

Everyday Proof

Accidents, deliveries, agreements, and moments you may need to stand behind later. Capture them with proof built in.

⚖️

Newsrooms, Legal & Insurance

Submit tamper-evident, court-ready media to the organizations that need it, with cryptographic timestamps and a full chain of custody.

For Organizations

Partner with Sootru

The proof you create is the proof they require. Newsrooms, insurers, legal teams, and NGOs use Sootru to receive media they can trust, verified with cryptographic proof before anyone acts on it.

📥

Receive Verified Media

Contributors or the public submit media straight into your review queue, each piece already checked for tampering. Keep intake open to anyone, or private to a registry of devices you invite.

✓

Review & Chain of Custody

Review with full cryptographic metadata, approve, reject, or flag, and export a chain-of-custody PDF. Every decision is logged with who made it and when.

📡

Field Tools Built In

Live upload streams a recording to you as it happens, so footage survives even if the phone is lost or seized. Dispatch reporters with Field Ops, and screen audio for AI voice deepfakes.
