BDB: Digital identities – steps on the path to an ID ecosystem


Digital identities have now become an integral of part of our everyday lives. Nine out of ten Germans use the internet, around 80 per cent make online purchases and two thirds of them use online banking.

1 Executive summary

Digital identities have now become an integral of part of our everyday lives. Nine out of ten Germans use the internet, around 80 per cent make online purchases[1] and two thirds of them use online banking.[2] This trend has resulted in the need for digital identity data, including personal log-ins, which now form part of every digital customer journey. However, these are usually stand-alone solutions, which means a digital identity needs to be set up for each provider. In Germany, there is still a lack of available and widely accepted solutions with which people can digitally identify themselves to business partners everywhere (i.e. across various sectors). This is not only due to the lack of interoperability among existing solutions, but also because the identity data collected by businesses may not be used externally. The resulting lack of widely available digital identity data is holding back the urgent digitisation of Germany, and also of Europe.

It is, therefore, all the more important to create an ecosystem for the use and management of digital identities that can be employed across sectors and providers. The aim must be to enable people and, by extension, companies and things (Internet of Things) to be seamlessly integrated into digital value creation processes based on digital identities. At the core of an ecosystem of this kind is the provision of identity data that have already been confirmed by one party (e.g. a bank) and which other business partners can rely on. The identity data should be controlled by the respective identity subject, in keeping with the principle of digital sovereignty and in line with data protection legislation. 

Businesses must work together with government to achieve this goal of a flourishing ID ecosystem. It would require new and close cooperation between the public and private sector, whose objective might even extend to formulating standardised procedural and organisational rules (a governance structure) as well as minimum technical standards. The ecosystem would not compete with existing providers of identity solutions, on the contrary, it would allow them to (further) develop their offers and innovations in a joint environment.

However, to achieve this, the legal and regulatory requirements for verifying identities, which are currently inconsistent, need to be harmonised across the different economic sectors. The only way to ensure that the new standards are widely accepted and that the market can adapt to them quickly is for the ecosystem to allow identity data to be used and exchanged across all sectors and for all parties. To achieve this, there needs to be equivalent requirements for the identification processes and mutual recognition by the respective supervisory authorities for all the regulated areas. The most effective way to attain full harmonisation would be by creating a standardised, cross-sector legal framework. 

The ID ecosystem should be launched as a national initiative which could then also be developed into a standardised European framework and interoperable identity solution. European payment transactions provide a good example of how the rules and technological standards might be standardised. The private banks expressly welcome the German government’s initiative launched late last year to create an open European ecosystem of digital identities.

In order for an ecosystem of digital identities to become a reality, the current legal framework needs to be adapted by incorporating the following measures.
  1. There must be a general equivalence of requirements for identification processes in sector-specific rules (including in anti-money laundering and terrorist financing, in the telecommunications sector, the public sector and for trust services). Where these rules are based on European legislation, full harmonisation in the form of a European regulation will be required.
     
  2. The most effective way to achieve full harmonisation would be using a single cross-sectoral European legal framework, which could then act as a reference for sector-specific regulations. This would also ensure that the scope of the data collected by those obliged to check identities is identical in order to make them re-useable throughout the EU.
     
  3. Furthermore, the legislator must continue to create the framework conditions required to ensure legal certainty in the relationship between identity verifier and issuer. This should also include taking account of questions of legal responsibility, such as liability limits, in order to ensure a fair balance of interests and to provide the necessary incentive.

The upcoming revision of the eIDAS Regulation[3] should be used to define horizontally standardised requirements in the sense of full harmonisation at European level, thereby making the whole cross-border verification process much easier.
