Dr Michael Veale said that using a centralised data app will give away personal data of themselves and others they have been in contact with, which is complex from a data security and consent perspective. He also said that cyberattacks on the technology could be plentiful as people could try and find the location of celebrities or other public figures. It also becomes difficult to compare and conflate apps with overseas travellers.
Ivana Bartoletti reinforced the point that the framing of the app had been bad for public trust. She stated that the app was being introduced at a time of lowering COVID deaths and relaxation in UK policy, which may make the public question the need for the app, which could reduce uptake.
Professor Johannes Abeler made the international comparison using a survey data from the UK, France, Germany, Italy and the US. He said most people cited privacy as a concern, but that they would install the app anyway, suggesting privacy would not necessarily stop people downloading the app.
Steve Clark said that data through the app at this point is anonymous and may protect yourself and your community from a potentially deadly disease making it little problem. However, having population-wide data in a centralised system could be different.
