Dot2Dot was inspired by Dottie Howe, and has been created by as a joint venture between Faye Grundy and Dan Howe.

We’ve talked to UK experts, and we were surprised to find there wasn’t a solution in place.

China and South Korea have both controlled the spread of the virus, but experts are concerned that when they reduce the lockdown, the virus will start spreading again.

China’s control of the virus surprised epidemiologists who thought this was impossible. China achieved this by a combination of strong state authority, huge investment in contact tracing, proactive testing and isolation and (probably) innovative technology.

At this point, it’s not clear if Western Democracies will try to duplicate this approach. See here for more information on this topic.

This is complex. To be useful at population scale, you need a large percentage of the population using the App. This may be easier to achieve in China, where WePay and AliChat are pervasive, but it’s much harder in other countries. That said, when the alternative is manual contact tracing, any digital assistance can save a lot of time.

The mobile phone network includes built-in location tracking of all devices – it has to do this, because the network needs to know which mast to send your next call to. This data is recorded by the network operators and with the right laws might be used for help with contact tracing. However, this data isn’t quite as good as GPS data, because a single phone mast may cover a wider area (there are techniques to triangulate) – and extracting and working with this data for whole populations is quite challenging technically!

Gonorrhea, HIV, TB, Ebola and even Measles. 

Right now, we’re still developing the first version. We’re hoping to get grants or donations to fund development of the system, and then we hope to find real world users. We are not aiming to make large profits from this software, and we hope to be able to make it available at low cost to places that can’t afford other solutions. But we need to fund development and promote the concept.

We want Dot2Dot to reach the market quickly and on a sound financial footing so we can continue development. At this point, we think open source might make this harder. We’ll keep this under review, and if it seems better to open-source the system, we will.

Vestigo is fully compliant with UK GDPR, and we are conscious of the level of personal data the system will maintain. Within UK law, there are exceptions within the Data Protection Act 2018 for collection of sensitive personal data for the purpose of infection prevention and control – it provides specific mechanism for how that data must be treated and disseminated. Once an outbreak is contained, all data would be securely destroyed by the system.

We note that privacy is handled differently in different countries, and we will need to review the necessary rules on a per-country basis.
