Digital signatures are the most advanced and secure type of electronic signature.
They are used to comply with the most demanding legal and regulatory requirements because they provide the highest levels of assurance about each signer’s identity and the authenticity of the documents they sign.
Digital signatures use a certificate-based digital ID issued by an accredited Certificate Authority (CA) or Trust Service Provider (TSP) so when you digitally sign a document, your identity is uniquely linked to you.
The signature is bound to the document with encryption, and everything can be verified using underlying technology known as Public Key Infrastructure (PKI).
What makes a digital signature so secure?
A digital signature is built to prevent tampering.
It’s created, protected, and surrounded by the highest levels of security – from the time the digital certificate is issued to the time the signed documents are archived and beyond.
Here are the main reasons a digital signature is so secure:
Digital IDs are trusted
Compliant, certificate-based digital IDs come from accredited providers. You need to prove your identity before you can get one.
It’s unique
Every time a document is signed, a unique digital certificate and PIN is used to validate the creators credentials and prove they are who they say they are.
It’s easy to validate
Both the signed document and the digital signature can be re-validated by a CA or TSP for up to 10 years after the signing event.
