CDA2: Anti-Deepfake Camera

Prove your photos and videos are real. In a world of deepfakes and AI manipulation, CDA2 gives your photos and videos a unique digital fingerprint — so anyone with the app can verify they're authentic and unedited.

🔒 YOUR PRIVACY COMES FIRST

Your photos and videos NEVER leave your device unless you share them.

When you capture media, CDA2 generates a SHA-256 cryptographic hash — a mathematical fingerprint. Only this hash syncs to the cloud. Never the photo itself.

• It is mathematically impossible to recreate your photo from its hash

• No one — not even us — can see, access, or recover your media

• Use Anonymous mode — no email or personal data required

• Export or delete all your data at any time

• Review our privacy policy directly inside the app

Your trust is not optional. It's our foundation.

🤝 SHARE & VERIFY WITH OTHERS

CDA2 isn't just for you — it creates a chain of trust between people.

Here's how: you capture a photo with CDA2 and send it to someone. The recipient opens CDA2 on their device and verifies it. The app checks the file's hash against the cloud record — if it matches, the photo is confirmed

authentic and unmodified. If even a single pixel was altered, verification fails.

⚠️ Important: share photos using methods that preserve the original file — email attachments, cloud drives (Google Drive, Dropbox), Bluetooth, or USB transfer. Platforms like WhatsApp, Instagram, or Facebook often compress or

re-encode images, which changes the file and breaks verification. When in doubt, verify after receiving to check.

📸 KEY FEATURES

🔐 SHA-256 Authentication — Every capture gets a cryptographic fingerprint. Even one pixel change produces a completely different hash.

☁️ Cloud Hash Sync — Hashes sync across devices for cross-user verification. Works offline — unsynced items queue and upload when connectivity returns.

✅ Batch Verification — Verify multiple photos and videos at once with a clear results report.

🖊️ Custom Watermarks — 6 positions, 6 styles, adjustable size, opacity, colors, and background shapes.

📷 Full Camera Suite — Front/back camera, flash (off/on/auto), self-timer (3/5/10s), photo and video modes.

📁 Gallery & Management — Filter by type, multi-select, rename, share verification info, full-screen viewer.
