Advanced eSignatures

What are advanced electronic signatures?

Advanced electronic signatures (AES) are a type of e-signature defined by the eIDAS regulation that is securely linked to a specific person using a special electronic seal. This helps confirm the signer’s identity. AES are sent through a secure electronic delivery system that provides proof and records of the signing process, in the form of audit trails. They often include a unique digital certificate to ensure authenticity.

In accordance with eIDAS, advanced electronic signatures must meet the following criteria in order to qualify:

Correctly identify the signer
Be specifically linked to the signer and only them
Have been created using eSignature data that the signer has full control over and confidence that they have the sole ability to sign it
Connected to data in a document that the signer(s) can monitor for any further changes

When should you use advanced electronic signatures?

Advanced e-signatures include additional security and identity verification measures compared to simple e-signatures, making them ideal for higher-risk document transactions involving sensitive or personal data. Businesses across many industries, such as healthcare, education, finance, and the government, utilise advanced e-signatures for their digital document workflows. The robust criteria to protect and verify e-signatures offer peace of mind to organisations and signers that their documents and data are secure and legal.

Are advanced e-signatures legally binding?

Yes, advanced electronic signatures are legally binding. If questioned or disputed, the in-depth verification process and audit trails can be referenced to support the security and authenticity of the signature.
