[v4.52] Define signature qualities
Content
This article clarifies the definition of signature qualities. You will learn more about the individual qualities and how to define and change signature qualities.
1. What are signature qualities and what types are there?
Electronic signatures increase users' efficiency and their flexibility in terms of time and place. Since documents may be subject to different security and legal requirements, we distinguish between three types of electronic signature quality according to eIDAS or ZertES:
Simple Electronic Signature (SES or EES)
Advanced Electronic Signature (AES or FES)
Qualified Electronic Signature (QES)
XiTip
To determine which signature you should use for which process in your context, it makes sense to define an internal regulation.
1.1. Simple electronic signature
eIDAS recognises three security levels. The simple electronic signature (EES) or standard electronic signature (SES) is the first and simplest security level.
SES can be used wherever a QES is not required. It is used, for example, in protocols, documentation and general terms and conditions.
XiTip
The SES does not require a certificate from the signatories. Nevertheless, in order to meet the highest possible quality standards, XiTrust always selects a qualified company seal for the simple electronic signature as well. Customers of the Business or Enterprise Cloud can use the XiTrust MOXIS company seal. Customers of the Enterprise Cloud or MOXIS On-Premises can store a qualified company seal for their company themselves. For more information about the XiTrust company seal, please contact your responsible XiTrust representative.
1.2. Advanced electronic signature
The advanced electronic signature (AES) must meet certain requirements:
Timestamp
Possibilities for verifying the identity of the signing person
Signing of the signature by a professional service provider such as XiTrust
Integrity and immutability of the signature through the use of encryption techniques and mechanisms that ensure that the document cannot be modified.
The advanced electronic signature is used for purchase or rental agreements.
1.3. Qualified electronic signature
The qualified signature (QES) according to eIDAS and ZertES represents the highest level of security for electronic signatures.
XiTip
QES: MOXIS uses the highest security standard for electronic signatures
In accordance with Regulation (EU) No. 910/2014 on electronic identification and trust services for electronic transactions in the internal market (eIDAS Regulation) and the Swiss Federal Act on Certification Services for Electronic Signatures, a MOXIS electronic signature is almost equivalent to a handwritten signature. It is not the signature itself that is decisive, but the technical and legal certification process in the background.
2. What signature qualities does MOXIS offer?
The following parameters define the signature qualities in MOXIS:
the iteration level
the security and legal recognition of the document
2.1. Levels of signature quality at the internal level
The following levels are available for the signature quality at the internal level (see Table 1):
Level 1: Approval
Level 2: Simple signature
Level 3: Qualified signature
2.2. Levels of signature quality at the external level
The following levels of signature quality are available at the external level (see Table 1):
Level 1: Simple signature
Level 2: Advanced signature
Level 3: Qualified signature
The signature qualities at the external level are described in the articles Creation of external orders and Advanced signature for external signatories.
2.3. Common signature qualities in MOXIS – overview
Signature quality | Iteration level | Description |
---|---|---|
Approval | Internal | This signature quality can be selected when it is necessary – regardless of the iteration level – to merely confirm that a job can be forwarded to the next iteration level. In this case, no signature is left in the document. |
Simple Signature | Internal/External | This form of signature quality is suitable for internal documents or written processes for which unequivocal verifiability of the signing person or their certificate is not absolutely necessary. |
Advanced Signature | External | If the liability risk for documents without formal requirements can be calculated, this signature quality can be used. The qualified electronic seal, which is left in the document by FES, guarantees the authenticity and integrity of the document and confirms the time of the signature. A certificate for the signee is not required. The signing person is identified by means of authentication via SMS-TAN or password. It is also possible to track biometric characteristics and technical device information. Examples: Sales and rental contracts, high-value contracts |
Qualified Signature | Internal/External | This signature quality has the highest security level and should definitely be used for all documents that are subject to a formal requirement and for which there is a high liability risk. The QES is based on a qualified eIDAS or ZertES certificate of the signing person. In addition to guaranteeing the authenticity and integrity of the document, the QES ensures the identity of the signing person according to the highest possible legal requirements by:
This signature fulfils the legal requirement of a handwritten signature. The signing person requires a digital identity (e.g. ID Austria) and can thus be identified beyond doubt by means of the qualified certificate. Examples: employment contracts, official business records such as audit reports, labour leasing contracts |

3. How do I set the signature quality in MOXIS?
Setting the signature quality in MOXIS is extremely easy. To define it, use the slide control (see figure 2) when creating a new job and specify the quality that the signature should have.
XiTipp
In the Enterprise version, the actual signature quality depends on the process configuration defined by the administrator. Therefore, if you are unable to select certain signature qualities, please contact your in-house administrator.

4. How do I change the signature quality in MOXIS?
Changing the signature quality is also done intuitively by adjusting the slide control. The quality of a signature cannot be mixed within an iteration level.
XiTip
If the signature quality of an iteration level is changed after recipients have been added, the system removes contacts from the iteration level that lacks the permissions.
You will receive a warning (see figure 3) that contacts will be removed.
