eDIAS Approved Electronic Seals

Esign provides eDIAS regulated Electronic Seals, which were introduced as a solution for legal entities. They are recognised by the European Union and can be considered as an electronic signature for a business or an organisation.

E-Seals certify the integrity and origin of documents. For example, a company may apply an electronic seal on a contract before sending it out for signature.

Electronic Seal vs. Electronic Signature

Even though they both rely on digital certificates, electronic seals and electronic signatures address different use cases in Europe, under the eIDAS regulation. An electronic signature can be used only by an individual to sign documents, such as contracts and applications.
However, electronic seals are used by (entities)—including organisations and governments—to show evidence of origin and integrity of documents.

With EU Advanced Electronic seals, a sender with the necessary user permissions, can add electronic seals to be applied to the document in the specified order in the workflow. An envelope can contain both electronic seals and electronic signatures if required.

Frequently Asked Questions

What are Electronic Seals?

Electronic Seals provide a means to certify the authenticity and source of documents. A typical scenario involves a company affixing an electronic seal onto a contract prior to sending it for signing.

Are Electronic Seals Legally Recognised?

Electronic Seals were introduced as a solution for legal entities, allowing them to protect the authenticity and integrity of electronic documents and data. An Electronic Signature is based on the same technology as an Electronic Signature and also can be Advanced and Qualified.

The eIDAS regulation states that a Qualified Electronic Seal shall enjoy the presumption of integrity of all data and of correctness of the origin of that data to which the Qualified Electronic Seal is linked. 

Is an Electronic Seal valid?

An electronic seal serves a valuable purpose in preserving the integrity of documents sent by a legal entity. However, it’s important to note that an electronic seal does not replace the need for electronic signatures. Instead, its primary function is to ensure authenticity, providing recipients with confidence that they have received the original, unaltered document.

Distinguishing Electronic Signatures from Seals

While an electronic seal and an electronic signature are technically similar, there is a notable distinction between the two. An electronic signature can be linked to either a natural person or a legal person/entity, whereas an electronic seal is exclusively associated with a legal person/entity. This difference highlights that electronic signatures have broader applicability, whereas seals are specifically tied to legal entities

What are the Use Cases of Electronic Seals?

Electronic seals have several practical applications, such as:

  1. Ensuring Data Integrity
  2. Sealing Automated Documents
  3. Confirming Automated Processes
  4. Securing Legal and Contractual Documents
  5. Maintaining Regulatory Compliance

These are just a few examples of how electronic seals are applied to protect the authenticity, integrity, and security of various types of documents and transactions.

Can an Electronic Seal Replace a Signature?

While an electronic seal shares similar mechanisms with an electronic signature, it differs in its purpose and implications. An electronic seal does not signify a commitment or engagement from the signatory regarding the document’s content, but rather focuses on ensuring the authenticity and origin of the data.

Here’s a breakdown of the distinction:

  1. Signature Commitment: A signature implies that the signatory has reviewed and agrees to the content of the document. It represents a personal endorsement and acceptance of the terms or information stated within the document.
  2. Seal Authentication: An electronic seal primarily serves to authenticate the integrity and origin of the data in the document. It assures the recipient that the document has not been tampered with and originates from the intended source.

While both electronic seals and signatures have their roles, it’s important to understand that using an electronic seal alone may not convey the same level of commitment or acceptance as a signature. If the document requires the explicit agreement or endorsement of the signatory, it is advisable to incorporate an electronic signature to signify consent and engagement.

Ultimately, the choice between using an electronic seal or signature depends on the specific requirements of the document and the desired level of commitment from the signatory.

Is the E-Seal Applied to Every Document in an Envelope?

With eSign, the electronic seal is only applied to the document that you have applied it too. Therefore, if you send 5 documents in an envelope, you only have to apply the e-seal to the document that requires it.
