Secure identity

A secure identity means that the identity cannot be manipulated or falsified and used for improper purposes. It guarantees complete consistency that a person is actually who they say they are. The identities of objects or processes can also be secured accordingly.


Electronic seals are data linked to electronic information that can be used to verify the authenticity and integrity of the sealed electronic information. In contrast to electronic signatures, electronic seals are applied by authorities and companies, for example.


An electronic signature is data linked to electronic information that can be used to identify the signatory or signature creator and verify the integrity of the signed electronic information. There are three different signature levels (qualified, advanced and simple). As a rule, the electronic information is electronic documents. The electronic signature therefore technically fulfills the same purpose as a handwritten signature on paper documents. Electronic signatures are only assigned to natural persons, while electronic seals are available for public authorities and companies.

"The basis for the digital wallet." The term self-sovereign identity is also translated as self-determined digital identity. It is the basic prerequisite for modern eGovernment and the future of ID cards, Post-Ident procedures and dealing with authorities. To make this possible, the SSI approach in the highest expansion stage (ambition level 3) pursues a decentralized strategy based on blockchain: users are given full access to their personal digital identity, which they can manage independently. They are not dependent on a central identity service provider

It defines the cooperation obligations of providers who provide trust services (such as the creation, verification and validation of electronic signatures) and determines the responsible national supervisory authority in this context.


Confirmation by means of evidence that an assertion meets certain requirements and that the facts to be verified are therefore true.


The aim of encryption is to subject data to a mathematical transformation in such a way that it is impossible for an unauthorized person to reconstruct the original data from the transformed, encrypted data. However, in order for the encrypted data to remain usable for its legitimate user, it must be possible to generate the original data from it again by applying an inverse transformation.

Confidence level

The security or trust level indicates the degree of trustworthiness that a digital administrative service requires. The more confidential the data is, the better it should be protected.

The VideoIdent procedure is used by banks to open an account, by mobile phone providers before issuing a SIM card, etc. In contrast to a visual check with a physical presence, the visual check in the VideoIdent procedure takes place via the live video image. The verifier guides the person to be identified through the identification process.
