Qualified electronic signature is the digital equivalent of a handwritten signature, which has full legal force. It enables secure and reliable signing of electronic documents. However, in order to be sure that the document you received was actually signed with a valid signature, you need to verify its authenticity. Here are the steps to help confirm the validity of a qualified electronic signature.
How to verify a qualified electronic signature?
1. use dedicated signature verification software
Qualified signature providers provide tools for verification, such as Sign, ProCertum SmartSign, Sapphire, Sigillium. With these applications, you can verify that a document is signed and that the signature is valid. However, they do not generate any evidence.
