Question details
Users are experiencing an issue where Topaz signature pad signatures can be removed by unauthorized users following an Adobe Reader DC software update.
- Product
- Adobe Reader DC / Topaz Signature Pad
- Device & OS
- not provided
- Scenario
- Securing signed PDF documents against unauthorized alterations or signature removal.
- Observed behavior
- A person who did not sign the document is able to click and remove the Topaz signature from the PDF.
Ensure you have administrator privileges to install new drivers on your computer, and verify that your PDF document doesn't have existing restrictive permissions that conflict with the certification process.
Verify and Certify the Digital Signature Workflow
Use a certified digital signature rather than a simple image-based signature, and lock the document after signing to prevent tampering.
If a signature is applied merely as an image stamp, it lacks cryptographic protection and acts like a standard image object, which anyone can delete. Transitioning to a certified digital signature workflow ensures the document's integrity.
Open your PDF document and navigate to the Tools menu to initialize the Topaz signature process.
Instead of inserting an image or stamp, ensure the Topaz integration is configured to apply a cryptographic Digital Signature bound to a certificate.
During the signing process in the dialogue box, look for the checkbox labeled 'Lock document after signing' and check it.
Save the document. This certification step ensures that any further changes, including attempts to remove the signature, will invalidate the document.
Update Topaz Software and Drivers
Compatibility issues caused by recent Adobe Reader DC updates can often be resolved by installing the latest Topaz signature pad software.
Securely Sign and Manage PDFs with WPS Office
If you are experiencing persistent compatibility issues with Adobe Reader DC plugins, consider switching to WPS Office. It provides a lightweight, comprehensive PDF toolkit that allows you to securely sign, edit, and manage your documents for free.
- 1. Download WPS Office: Visit the official WPS website to download the free installation package.
- 2. Open your PDF: Launch WPS PDF and open the document you need to sign securely.
- 3. Apply a signature: Navigate to the PDF Sign tab to insert and securely lock your digital signatures.
Frequently Asked Questions
Why did my Topaz signatures become removable after an Adobe update?
Adobe updates can occasionally reset security settings or alter how third-party plugins function. If the update caused the plugin to default back to an 'image-based' stamp rather than a certified digital signature, the signature loses its cryptographic protection and can be easily deleted.
What is the difference between an image-based signature and a digital signature?
An image-based signature is simply a graphic or picture of your handwriting placed on the PDF page, which anyone can select and delete. A digital signature uses a cryptographic certificate to bind your identity to the document, locking it and tracking any unauthorized modifications.
How do I ensure a PDF document is locked after signing?
When applying a digital signature in professional PDF software, the signature dialog box will typically present an option to 'Lock Document After Signing' or 'Certify Document'. Checking this box ensures no further edits or signature removals can occur without breaking the document's validation.
Are Topaz signature pads compatible with WPS Office?
WPS Office fully supports standard PDF digital signatures and importing signature images. However, specific hardware plugin integration depends on whether Topaz Systems provides dedicated drivers for alternative office suites. You can always use Topaz software to generate a signature image or certificate, which can then be securely imported into WPS.
