Solution 1Recommended

Use Digital Signatures and Read-Only Configurations

Set up your interactive PDF to lock form fields automatically after submission or approval to ensure document integrity.

While a simple approval checkbox can be used, a genuine digital signature provides much stronger cryptographic validation for approval workflows. It ensures the document cannot be tampered with after the director signs it.

1
Insert Form Fields

Open your PDF form editor and add the necessary text fields, checkboxes, and date fields for the employee to fill out their request.

2
Add a Digital Signature Field

Insert a Digital Signature field specifically designated for the director's approval or rejection action.

3
Configure Read-Only Actions

Right-click the Digital Signature field, open its Properties, and navigate to the 'Signed' tab. Select the option to mark 'All fields' or 'Specific fields' as read-only once the signature is applied.

4
Distribute and Approve

Save the form and send it to employees. After an employee fills it out, the director can review the document, click the signature field to apply their digital ID, and lock the document.

Use Digital Signatures and Read-Only Configurations
Enhanced Security: Using a digital signature instead of a standard text field ensures that any modifications made after approval will immediately invalidate the signature, providing a clear audit trail.
