In-App Secure PDF Annotation


I'm using an annual subscription level SharePlus v4.1.1027 to annotate a PDF. I would like to use the 'free drawing' tool to sign documents with my signature. Is there a way to make this signature annotation secure and thereafter uneditable?

My problem is that at this stage after I sign (annotate) the document and save it to my SharePoint site I am still able to manipulate/copy/delete the signature from a desktop PDF reader (Foxit PDF Reader) and SharePlus if I reopen the PDF. Hypothetically this means my signature could be copied and used elsewhere.

Perhaps a solution involves something to do with the PDF security/privacy settings, but is there any advice on a SharePlus end?

    Hello Tim,

    Thank you for your support request!

    SharePlus doesn't have a way of flattening the PDF.

    You can try opening the PDF in a 3rd party app like PDF Expert, Adobe Reader or any other PDF tool. Then, once flattened, you can save it back to SharePlus.

    I hope this helps.

    Take care,

    Hello, I think you should consider obtaining a digital signature certificate from a trusted certificate authority (CA). This certificate will provide a higher level of security and integrity to your digital signature. PDF readers and software that support digital signatures will validate the certificate, ensuring the authenticity of the signature and preventing tampering.
