How does the QR verification actually hold up if someone just screenshots the signed PDF and shares it without using your platform, would the audit trail still flag that as the original copy?
@hakan38824 If a user takes a screenshot of the signed PDF and shares it, the security system actually holds up incredibly well against tampering, though there is a specific visual loophole to keep in mind.
Here is how the QR verification and audit trail handle this scenario:
1. The QR Code Still Links to the Truth
If the screenshot is clear, scanning the QR code will still work perfectly. The QR code contains an embedded URL with a unique identifier linked to a SHA-256 cryptographic hash of the original document.
When scanned, it will always direct the verifier to the tamper-proof audit trail hosted on PDF Verified.
The moment a user completes signing a document and prompts a download, that unique digital fingerprint (hash) and its complete audit history are securely locked into the platform.
2. The Screenshot File Will Fail Integrity Checks
If someone tries to take that screenshot file (e.g., a .png or .jpeg) and upload it directly into the platform’s verification tool to check its validity, it will fail completely.
A cryptographic hash acts like a unique digital fingerprint of the file itself.
Because a screenshot changes the file format, strips the original metadata, and alters pixel data, its SHA-256 hash will be completely different from the original PDF generated at download.
The platform will instantly flag the screenshot file as unverified or altered.
3. The Visual Loophole (What to Watch Out For)
While the QR code securely proves that a valid, original document exists on the platform, it cannot stop someone from using image-editing software (like Photoshop) to alter the text visible on the screenshot itself before sharing it. but the platform solves this by showing you the original file so youy can compare sensitive files the original person who made it is prompted to authorize to let you view it. Now if lets say its a sensitive document one needs to follow due legal processes per country
