In episode 6 of The Decentralized Web podcast, Jonathan Bingham is joined by Paul Henninger, Head of Lighthouse and Partner at KPMG. Lighthouse is KPMG’s data analytics and engineering team that develops data and artificial intelligence solutions for businesses. During the conversation Paul explains the concept of ‘the digital self’ in a world driven by data and explores decentralization’s key role in tackling the problem of interoperability across healthcare systems, and how this can provide better care for patients and even give birth to new industries.
The Digital Self
The digital self can be described as the data people leave behind on the internet. Most of this data is produced and stored in centralized systems. Now however, the average citizen is cognisant of the way their data is stored and shared. In fact, people are not only aware that their digital self exists, but increasingly people are much more intentional about the data they share. In the past it was very difficult for consumers to have any control over the data they left behind, now it is common for companies to ask its users about what data they would like to share, and how.
The Problem of Centralized Data – For Consumers and Organisations
The Benefits of Decentralization
Centralization has been a barrier to realizing the benefits of innovation. The problem lies in the fact that centralized systems collect data in one place. The main pain point for organisations is to get the right data at the right time. The solution for this problem is a decentralized system where people can choose what data they give out, and the time the other party receives it. The simplicity of letting people own their data solves many problems that large organisations face. Decentralization avoids issues that come with selecting the right technology to handle data, or security issues caused by having data stored in one place
Trusting People with Data
The question of whether society at large should trust people to own and manage their data has no straightforward answer. It is true that decentralization will have unintended consequences, such as a person only willing to share data within a niche community. In a centralized system this person’s data would be more accessible. However, decentralization is about giving people control, it provides people a middle ground between opting into a completely centralized system versus having no digital presence at all. Decentralization requires trust from institutions that the public are capable of controlling their own data and that this is desirable for people, and for organisations.
Healthcare Data and Decentralization
One use case for decentralized data systems is in healthcare. A contemporary example is the current backlog of care facing NHS trusts in the UK due to the pandemic. If patients carried around their own data they could travel between trusts and see different healthcare professionals, this would remove the pain for providers when it comes to accessing patient data from a centralized system. Practically for a patient this would include less form filling, and for hospitals it would improve interoperability and the diffusion of data. The NHS Data Saves Lives strategy perfectly exemplifies this approach. In order to improve health outcomes at a population level the public must take control of their health, and this now necessitates that they should have control over their health data.
