Advanced Electronic Signature (AdES)

An Advanced Electronic Signature (AdES) is a secure, digital way of signing documents that goes beyond a simple electronic signature. It verifies the identity of the signer and ensures that the signature is unique to them. An AdES links the signer's identity to the signed document, making it tamper-evident; any changes to the document after signing can be detected. They comply with strict legal standards, ensuring that they hold the same legal weight as traditional handwritten signatures, making them reliable for important transactions in business and legal contexts.
