Key Advantages

  • Cost: The cost per authentication with the cidaas ID Validator is 4.50€ for an eIDAS compliant verification (slightly less for other verifications) compared to 10-16€ per verification for other verification procedures such as Video identification.
  • Fully Automated: There is no need to interact with an employee, making it more convenient for the user.
  • No Waiting Time: The system can handle multiple cases simultaneously, so users do not have to wait before starting the identity verification.
  • eIDAS Compliant: The cidaas ID Validator will provide a certified eIDAS compliant identity verification that meets the highest market standards.

What is eIDAS?

The eIDAS Regulation (Electronic IDentification, Authentication, and Trust Services) standard was established in 2016. It sets out EU-wide regulations on electronic identification and electronic trust services to create a uniform framework across all the 28 EU member states and the European Economic Area. It is a milestone towards creating a predictable regulatory environment and intends to help businesses, citizens, and public authorities carry out secure and seamless electronic interactions.

Business Use Cases and Scenarios

The need for strong identity verification based on ID documents has become more prominent and critical in the modern digitized world. Especially in highly regulated industries like financial service providers for processes like opening a bank account (GWG), etc.

Identity theft is a grave concern for legitimate users whereas cyber criminals benefit from it. Thus, Know Your Customer (KYC) plays a crucial role in different industries. As new and innovative digital channels are introduced and scaled in the retail sector, and not all customers want to identify themselves on-site at the customer service desk, strong, online identification procedures are mandatory and in-demand.

Since mobility is also transforming business models, cidaas' Digital ID Validation is carving a niche in the following areas:

  • Identification for online business transactions: For specific contracts and business transactions like credit conclusion, the opening of a bank account, purchase of a prepaid SIM card, etc., an identity check is required by law. If these contracts are concluded online, the identity check with the cidaas ID Validator offers the advantage that the customer can quickly and comfortably carry out this check without interrupting the business process. In addition, the cidaas ID Validator will provide an eIDAS compliant and, therefore, secure and certified identity verification.
  • Car rental: When renting vehicles, it has to be ensured that the customer has a valid driving license. Often an identity check is added. This can be done conveniently with the cidaas ID Validator online and with only one check (if the identity check does not have to be eIDAS compliant).
  • Onboarding new employees: When new employees are onboarded in the company, they get many rights and access to sensitive data. Under certain circumstances, an identity check is necessary. This can be done reliably and quickly with the cidaas ID Validator.
  • Identification at events/restaurants: Due to the pandemic situation, frequent identity checks will likely become mandatory in the future at events such as concerts, sporting events, etc., or even when visiting restaurants, or museums. Thus, the cidaas ID Validator is useful in speeding up the verification process and reducing manual efforts.
  • Identification for official services: For official services and application verification during car registration, employee onboarding, etc., identification is paramount. Many of the services are already available online or being digitized. Here, the cidaas ID Validator helps perform the identity check so that the user can complete the relevant applications and services online.

Webhook Service

The Webhook Service typically connects two different applications (the trigger and the action applications) and is a way for one app to provide the other with real-time information on a process using JSON requests and responses.

To set up the Webhook Service on your app using the cidaas ID Validator, you'll need to do the following.

1. Create a new Webhook.

2. Subscribe the Webhook to the ID_VALIDATION_FINISHED event.

3. Provide a POST endpoint to accept the data.

4. Ensure that data is coming from your system by setting up an API key for the endpoint.

Example: Webhook Data

    "eventtype": "ID_VALIDATION_FINISHED",
    "sub": "852a5685-07fa-4954-8082-45d194f6ba19",

Overall Summary

This section displays an overview of all the system checks performed and the system decisions taken as a result of these checks. A reference image of this section is shown below.

Checks Performed on the Admin UI-Overall Summary Page

The cidaas ID Validator Admin UI (Overall Summary page) shall display a checklist of validation questions for the user and the system's response to each of those questions with a success icon for successful validation and error icon otherwise.

Does the person on the ID document and the person in the facial recognition match?

The ID Validator checks and compares the person being validated against the person on the ID card. If the biometric parameters of both match, the check is validated.

Did you use the front of a real ID document?

Authentic ID cards have several different holograms that can be used for validation. On the German identity card, one or more of these holograms can be found on the front side and can be used for validation.

You can find more details here.

This system check is done for the follwoing front-side security elements of the German ID card.

Type of Security Element Image Reference
OVC - Optical Variable Color
OVD - Identigram, contrast reversion
OVD - German Eagle

Did you use the back of a real ID document?

Similar to the front side validation of the German ID card, authenticity verification holograms can be found on the backside as well.

You can find more details here.

This system check is done for the following backside security elements of the German ID card.

Type of Security Element Image Reference
OVD - CLI (Changable Laser Image)
security thread containing user data

Did a real person do the facial recognition?

For this verification, the system verifies if the person was following the points with his eyes. Suppose a person is not looking on the screen or is not following the points on the screen, this check is rejected.

Are the checksums correct?

The Machine Readable Zone (MRZ) contains checksums that can be verified by applying some mathematic functions to the extracted data. You can find the information on how to calculate the MRZ checksum here. If this check gets through, the checksum is validated.

Is the ID document used valid?

The validity of an identity document is given if all of the following checks can be answered with a Yes.

  • Is the expiry date of the document in the future>
  • Is the issue date of the document in the past?
  • Is the time gap between the issue date and expiry date 10 years (might be different for some identity documents) or 6 years if the person is below 24 years old?

Do the front and back sides of the ID document match?

This check is validated if the front and back sides belong to the same document type, e.g., German Identity card.

Does the data (name, date of birth, etc.) on the front and back match?

This check is done to validate if data such as the expiry date, birth date, surname, given name, and document number present on the front and the back sides of the German identity card match.

Does the data on the ID document match your profile information?

If the user was registered using the surname, given name, and birth date; they also needs to provide their age and document number when initiating the validation process. This data is compared to the data on the identity card. This check is validated if both the data match.

If a validation attempt has been identified as fraudulent, it is mandatory to report this to the Bundesnetzagentur.

Therefor we provide a report button to initiate the action and provide additional information. In addition the expert info can be provided via a text field where the video and image data collected will also be sent.

If the validation went fine and checked by an expert, the expert labels will be stored with the Submit button.
