Photo Verification
How to check the integrity of a capture.
The core value of Verifield is the ability to prove a photo has not been tampered with.
Using the Web Verifier
You can upload any photo captured by Verifield to our online verifier tool. The tool will recalculate the image's SHA-256 hash and check it against our immutable ledger.
- If the hashes match, the tool will display the original, verified time and location data.
- If a single pixel has been changed (e.g., Photoshopped), the tool will flag the image as tampered and invalid.
