D-Trust eID Service and Authorisation Certificates

Securely identifying customers digitally with the online ID card

By integrating the online ID function into your digital offers, you can securely and unambiguously identify your customers in just a few minutes.

User-friendly identification process for your services

The use of online services has become a digital routine for many people. Many services offered by public authorities and companies require users to identify themselves. Certain providers – usually for legal reasons – need an identification procedure for their services that confirms the identity of the user at a high level of security. The procedure is mainly used for legally effective contracts, such as when opening bank accounts or taking out insurance policies and loans, and also when applying for public benefits.

The most secure means of identification is to integrate the online ID function into the digital services. According to the eIDAS Regulation, the highest level of trust is provided by the online ID function. With its eID service, D-Trust – a company of the Bundesdruckerei Group – offers you a secure and legally compliant identification procedure based on the online ID card that satisfies the requirements of the German ID Card Act and the technical guidelines of the Federal Office for Information Security (BSI).

Product details

With the eID service by D-Trust, you are not only able to identify your customers securely on the Internet, but you can also read out ID card data electronically at customer counters and points of sale (POS) and transfer the information to your processing system without errors. Thanks to standardised interfaces, this is a straightforward procedure.

Use the D-Trust eID service to integrate the eID service just the way you need it for your business model or administrative service. The following options are available:

(Online) Service provider

You identify your customers for your own service on the Internet.

On-site service provider

You read out your customers’ ID data electronically on-site.

Identification service provider

You take over the task of digitally identifying your client’s customers.

All ID documents issued in Germany with on online ID card function can be used for this purpose. Besides identity cards, such documents also include electronic residence permits (eAT) and eID cards for citizens of the European Union and nationals in the European Economic Area, also known as the EU citizen card. Anyone with an eID from other European countries that is confirmed according to the eIDAS Regulation can also be securely identified using the eID service.

As an identification procedure based on the online ID card, the eID service has a high level of security. In addition to the identity of the person holding the ID card, it also checks the authenticity and the revocation status of the ID document. The ID card data read out during the authentication process is encrypted and signed and then transmitted to the service provider via a secure SSL connection in adherence to the technical guidelines and laws. Service providers must have authorisation to access the ID card data.

To use the eID service, service providers need authorisation to read out data from the online ID card. This authorisation consists of a notice from the Issuing Authority for Authorisation Certificates (VfB) and a technical authorisation certificate for the requested service. Once the notice has been issued by the VfB, service providers can order an authorisation certificate from an authorisation certificate provider (BerCA). D-Trust is currently the sole provider of authorisation certificates in Germany and thus the only company offering the authorisation certificate and eID service from a single source.

Service providers can use the eID service for different government or private sector web applications to securely identify their users. Sample applications include:

  • Public administration:
    Applying for services such as student grants and loans (BAföG), vehicle registration and re-registration or the submission of income tax returns
  • Healthcare:
    Registering for services such as electronic patient records
  • Banks:
    Online opening of accounts, conclusion of loans and consumer credits
  • Telecommunications:
    Online activation of prepaid SIM cards
  • Other identification processes based on legal provisions

Connecting the eID service to the eID infrastructure is easier than it might seem at first glance. Integrate the eID service in just a few simple steps:

  1. Apply for the authorisation certificate at the BVA, the awarding authority for authorisation certificates.
  2. Once you have received your notice from the VfB, you conclude a contract with D-Trust GmbH to purchase the technical authorisation certificate and connect to the eID service.
  3. Implement the D-Trust eID service in your web service via a SOAP or SAML interface. Our reference system provides you with testing options using test IDs or the simulator PersoSim.

The eID service is implemented via a SOAP or SAML interface. You will receive a detailed integration manual and the current Software Development Kit (SDK) from our service portal after concluding the contract.

To use the eID service in your web application, you will need an eID client – installed on the user’s smartphone – in addition to the eID service. The eID client is software that establishes a secure connection between your online service, your customers’ online ID card and their smartphone or card reader. The most common eID client is AusweisApp2. This is available as open source software and can be deeply integrated into your web service using the Software Development Kit (SDK) of AusweisApp2.
