Smartphones on wheels? Giving back control to users is key to ethical data usage and acceptance in smart mobility ecosystems

· As companies shift from big data to small and wide data, SSI and Compute-to-Data become a new paradigm for how we interact with our digital world as ethical data usage is becoming a major concern.

A secure and simple digital identity can make mobility safer.

In the mobility sector, a secure and simple digital identity will be a game changer for users and developers. It will allow users, infrastructure owners and fleet owners (data subjects and data owners) to control their data in a way that was previously impossible, while also allowing developers to create better services by leveraging user data as an asset. The benefits of this approach are clear:

Self-Sovereign Identity and Compute-to-Data are key to control information in the digital age.

· SSI and Compute-to-Data are vital for protecting people from the negative impacts of digitalization as both are ways to regain control over personal data and sensitive information.

SSI and Compute-to-Data share core principles

1. Control — Users must be enabled to control their data. Control differs from just stating what data is associated with a user or what can be done with it.

Providing interoperable infrastructure for Self-Sovereign Identity and mobility services will be crucial

Interoperability is an essential aspect of any future mobility solution. Open standards will be needed to ensure that different systems can connect. Open-source software is needed to allow for innovation on top of the base platform. Interoperability will also make it easier for organizations that want to participate in the value creation process by investing in their own software or hardware solutions without locking themselves out of the standardized ecosystem.

Stakeholders should focus on value creation instead of data dominance

Data has unique properties that make it different from all other types of assets: it becomes more valuable the more it is used. Trust and data ethics form the fundament for this, unlocking the willingness and ability to sustainably share data to the extent needed to truly leverage this unique resource.

Self-Sovereign Identity and Compute-to-Data will protect people from the negative impacts of digitalization by enabling them to retain control over their own data.

SSI is a digital identity that is not controlled, but enhanced by existing authorities, as opposed to established identity frameworks such as government IDs or social media accounts that are not under the user’s control. Both concepts allow users to manage their information in a decentralized manner and make the most out of it.

With Compute-to-Edge data sovereignty will be further expanded and the Cloud-to-Edge continuum will be more secure.

You have seen the statistics: Gartner predicts that data volumes will reach 44 zettabytes by 2025, an increase of over a thousand times compared to 2017. Furthermore, Gartner says 70% of organizations will shift their focus from big to small and wide data by 2025.


The future of mobility is about Self-Sovereign Identity, technical data sovereignty and sustainable, ethical use of data. It will empower people to retain control over their own data and make mobility safer, more convenient, and more efficient for everybody.
