Notarius Digital Signature


ASET members increasingly use new technologies in their daily work. The documents they produce need to meet high standards of reliability. ASET members who wish to produce legally reliable digital documents in compliance with ASET’s requirements can now accomplish this task with CertifiO for Professionals – ASET Digital Signature (referred to as the “digital seal”). Digital seals are not to be confused with an electronic impression (scanned image) of a physical stamp.

After extensively evaluating the digital signature market, ASET has selected Notarius to provide the ASET Digital Signature to their members.

What do members need to know about digital signatures?

What is a digital signature certificate? 
It is a computer artefact issued and cryptographically protected by a certificate authority (Notarius) attesting to the authenticity of the information declared in the certificate. This information may include:

  • full name
  • email address
  • professional title
  • membership number
  • public key; and/or
  • validity period and the serial number of the certificate.

Notarius Partnership

Notarius provides the framework and the platform to allow its 38+ partners (including AAA, AALA, APEGA, LSA and ALSA) to issue trusted digital signatures to their members, without the trouble of managing the technological infrastructure related to the platform. Just as ASET controls distribution of the ink stamp, this partnership allows the association to be the exclusive provider of the ASET Digital Signature.

Members who receive an ASET Digital Signature can then start creating electronic originals and authenticating finalized documents. With the digital signature, these members use proven technology solutions that meet government standards and best archiving practices for electronic documents.

Features and benefits

When ASET members affix a digital signature to a document it:

  • guarantees the identity of the document – The origin of the document includes proof of the signer’s identity, the ASET professional affiliation and member category (at the time of the signature) as well as the date and time of the document’s finalization.
  • ensures the integrity of the document (as well as its data contents) – This ensures the document has not been altered since its completion.
  • establishes the authenticity of the document – The authenticity implies that everything necessary to prove its origin and integrity is embedded in the document. The digital signature must remain under the sole control of its holder. It cannot be shared nor delegated under any circumstances.


Notarius has been hard at work creating documents and videos to support ASET members with their digital transformation and showcase the functionalities and benefits of their digital signature tools.
