Mr Schneier said he believed in Sir Tim's vision of creating a new distributed data ownership model to challenge the "digital feudalism" of the big tech companies. "The problem is that your data is not under your control. It is on computers owned by lots of other people. And you have no control over it and you do not have access to it in ways that are useful to you," he said in a telephone interview.
Mr Schneier said it would be an immense challenge to create workable authentication and permission processes to enable Solid to work at scale, but he was convinced it was achievable. "It is 'going to the moon' hard rather than 'faster than light travels' hard," he said.
"It is easy if some big party is in control. It has this massive power that decrees this and this is allowed. But if you want to distribute that authority so that users are in control, it is a lot harder."
Inrupt was founded in 2017 to operationalise the Solid decentralisation technology, developed by Sir Tim's team at the Massachusetts Institute of Technology. Last year, Inrupt raised a "significant" sum of money, in excess of $10m, from interested tech companies, individuals and institutions to fund the company's development.
Some of the big tech companies privately dismiss Solid as a quixotic academic project that is unlikely ever to succeed because users are so path dependent on existing data platforms. But some of the biggest tech companies, including Apple, Google, Facebook, Microsoft and Twitter, are publicly backing the Data Transfer Project, launched in 2018, to help create an open-source, data portability platform that could integrate with Solid.
John Bruce, Inrupt's co-founder and chief executive, said the company was working on several pilot projects, including the one in Manchester.
"We are seeing if we can collectively deliver better healthcare to UK residents. At the moment that data resides in silos across the NHS. Wouldn't it be cool if it could be securely delivered straight to your nurse or your caregiver," he said. "You would then have a holistic representation of your healthcare."
