Signaturportal FAQ
- Easy signing without local installation: Documents can be signed directly in the browser without having to install additional software or plugins.
- Flexible remote signature: Signatories can participate in the signature process at any time, regardless of their location. The invitation is sent via email link; the actual signature is then carried out directly in the signature portal—even on mobile devices.
- Flexibly control multiple signatures: Workflows can be defined with or without a fixed order. Without a fixed order, participants can sign independently of each other; with a defined order, signatures are made one after the other according to the specified sequence.
The eIDAS Regulation on electronic identification and trust services contains binding regulations applicable throughout Europe in the areas of “electronic identification” and “electronic trust services.” The regulation creates a uniform framework for the cross-border use of electronic identification means and trust services.
According to eIDAS, the following categories must be distinguished:
- The simple electronic signature (“EES”)
- Fortgeschrittene elektronische Signatur (FES)
- The qualified electronic signature (“QES”)
No, you do not need any additional programs to sign using the CIB signature portal.
The CIB signature portal uses certified trust service providers (TSPs) to provide qualified signatures.
A VDA is an entity that creates, verifies, manages, or validates certificates and signatures/seals, for example. The highest level is the “Trust Center” – as a qualified VDA.
Yes, the user is identified via SMS through approved mobile phone providers. The prerequisite is that the mobile phone provider does not allow anonymous users.
According to eIDAS, an electronic signature is a legal term for the signature of a natural person on digital platforms. It enables the identification of the holder of the underlying certificate and the integrity of the document.
The term “digital signature” refers to the underlying cryptographic mechanism. The two terms are often confused or used imprecisely.
A digital certificate is an electronic data record containing specific information for identifying a natural or legal person. It is based on asymmetric cryptographic algorithms (division into private and public keys).
A digital certificate can be used to perform several functions, in particular, the electronic/digital signing of documents.
An electronic seal uniquely identifies a legal entity, such as a company or public authority.
Applying a seal to a document proves the origin and integrity of the sealed document, but is not considered a personal signature.
For this reason, we refer to seals rather than signatures.
A digital seal is, therefore, the electronic signature of a legal entity that guarantees the origin and integrity of a document.
