I agree with the intent here, but not the recommended means.
A personal data store is a collection of physical and cloud-hosted software components that provide for an individual data subject to manage, log and audit access to their data by other parties (Mortier et al., 2016).
While such facility is purportedly designed for a more active type of economic actor, directing instead of being directed by the emerging data economy (Crabtree and Mortier, 2016), is each actor to act alone?
Data potentially form valuable, actionable insight only when data flows in combination. Flow does not require static facsimile, and perhaps more pertinently, facsimile will by definition never be master. I cannot conceive my bank ever relying on my version of accounts. I cannot conceive of any party relying on a verified credential I may have stored to warrant a clean (no penalty points) driving license simply because I may have been penalised subsequently.
In fact, such stores are architecturally irrelevant before they’ve even seen wide adoption. Data must reside where it has contextual authority.
I contend we require insight into where our personal data is flowing and for what purposes (personally and socially material), entailing an interface into and onto the permissions and flows rather than anything resembling the metaphoric connotations of a store.
