Our recent Data Policy Network (DPN) evening considered some of the knotty issues around valuing data. We’re grateful to Jeni Tennison, Vice President of the ODI, who kicked off an evening of discussion by sharing her reflections on the topic. She drew on the ODI’s joint report on the Value of Data, co-authored with the Nuffield Foundation and the Bennett Institute for Public Policy.
I’ll try to capture some of the themes from our discussion in this blog, with the caveat that my efforts will be far from exhaustive. First, I’ll look at why we might want to value data in the first place. Then, I’ll highlight some of the challenges relating to valuing data, including defining the concept of value and enabling that value to be shared fairly. Finally, I’ll use real-world examples to show how we can work around those challenges to capture the benefits data can offer.
We can all agree that valuing data is difficult, and vitally important. If we understand the value of data, we can judge whether there is a fair exchange between those who generate (often individuals in the case of personal data), curate and use data. Longstanding Data Policy Network members will remember that we looked at equitable data sharing in a previous event. We may also want to treat data as an asset, similar to other intangible assets like intellectual property, where an understanding of its value can inform conversations about how to regulate or even tax companies that derive value from data.
The fact that data can be valuable in different ways and that we may want to value data for different purposes illustrates the first challenge: how should we define value? The answer might vary depending on why we want to value the data. Three examples show the range of possible approaches:
These examples show that value will often arise from data being used or shared. In the TfL example, commuters save time because a developer has used the data to build a journey planning app that helps the commuter navigate the city more efficiently. This property of data, the fact that sharing and using it can make it more valuable, makes data different from other types of tangible or intangible asset and leads to a second question: how to share value fairly between different parties?
As with approaches to valuing data, there are different models for sharing that value. For example, a company developing a new medical treatment based on NHS data might become a commercial success in revenue or profit terms. Some models allow financial value to be shared, for example the agreement between Sensyne Health and the Wye Valley NHS Trust. Sensyne gets access to patient data to power their AI-based clinical research and the Trust gets an equity stake and a share of royalties arising from discoveries. Patients in turn benefit from improved treatment and society as a whole benefits from better health. Fair value sharing can incentivise data use, which in turn increases the value of that data.
But the fact that multiple parties with different incentives are involved brings us to the question of trust. Unlocking the value in data relies on building trust between all of the parties involved. For personal data, that includes the individuals to whom the data relates. A focus on trust allows us to address the underlying driver for valuing data, without needing to actually place a value on data.
Sticking with personal data sharing as an example, how might we build trust between individuals, or society at large, and the organisations seeking to generate value from personal data? We had a few ideas:
I’ve written previously about techlash, surveillance capitalism and the theme of individuals being suspicious about how data about them is collected and used. The health sector, drawing on the three points on building trust above, provides a counterexample.
Researchers and commercial companies can access and use NHS data, but are subject to strict controls and well developed data governance systems including ethical review, technical controls like pseudonymisation and legal restrictions in contracts and licenses. Their work must comply with general data protection laws like the GDPR and specific rules governing confidential patient information. And they show benefits e.g. by publishing work in academic journals, paying license fees to access data and enabling advances in patient care.
Organisations like UseMyData show that building trust can turn suspicion about data use into individuals calling for their data to be used. The potential benefits are enormous.
