Safe & legal

The European ETSI standards ensure that the digital signature is set up in a technically correct manner. The signing process is primarily an authentication of the signer, who does this at the moment that he/she has taken cognisance of the document and agrees with its contents.

In accordance with the ETSInorm, Zynyo has recorded this agreement in the Deed of Signature, which then forms part of the signed document. This deed contains several crucial aspects of the digital signature:

  • Method of signature
  • Time stamp with time of signature
  • Sealing the document

The sealing prevents the document from being altered or falsified. The act of signing allows the signatory to prove its validity after signing, if necessary.
