Sign & Secure Adobe PDF with PDF Signing
Certified Document Services (CDS) is the first digital signing solution that allows authors to create Adobe® PDF files that automatically certify to the recipient that the author's identity has been verified by a trusted organization.
Authors of PDFs add digital Certifying Signatures and Approval Signatures to documents they distribute over the Internet. The process is the virtual equivalent to sealing a document and adding wet-ink signatures and assuring the recipient that the document is authentic, comes from a verified source, and the contents have not been tampered with since being published.

GlobalSign is an authorized participant in Adobe's Certified Document Services (CDS) program and operates under a stringent set of policies and standards developed by Adobe and audited by WebTrust to allow GlobalSign to issue Adobe recognized CDS Certificates, branded as PDF Signing Digital IDs, to individuals and departmental entities.
PDF Signing users can add Certifying and Approval Signatures to PDFs using a trust model used in Adobe Reader 6.0+ without installing any new plug-ins, configuring Adobe Reader/Acrobat to non-default settings, or needing to make confusing trust decisions.

How it works

Certifying Signatures
Using GlobalSign PDF Signing, PDFs can be certified by a person or department by adding a Certifying Signature, and when viewed will present the document recipient with a prominent "blue ribbon" displayed within Adobe Reader. Recipients can then easily determine the document authenticity and authorship. Prior to certifying the document the signer may specify the types of changes allowed for the document to remain certified (e.g. what is allowed without invalidating the Certifying Signature) such as "changes not permitted, form filling only or form filling and commenting".
Approval Signatures
PDF Signing allows PDFs to contain one or more Approval Signatures, added by individuals or departments, and when viewed present the document recipient with a "green checkmark" displayed within the PDF itself. Approval Signatures show which people or departments have consented to, approved or accepted to the contents of the PDF.
