Digital contact tracing will fail unless privacy is respected, experts warn Digital contact tracing will fail unless governments build the technology in a way that respects user privacy, a group of nearly 300 experts have warned.Digital contact tracing, pioneered by Singapore in late March, uses the Bluetooth connection in modern smartphones to keep track of meetings between individuals, in order to allow self-isolation instructions to be sent automatically to everyone a newly diagnosed patient has interacted with while infectious.It is possible to carry out such tracing without needing to build a centralised database of every meeting between individuals, which could be abused by authoritarian governments or overzealous officials: one proposal, backed by Apple and Google, sees every smartphone build a decentralised record of only the other phones it has interacted with, and waiting to hear from the state if any of those phones have been marked as infectious.But the NHS is understood to be focusing on a different approach, which uploads far more data. That brings with it numerous technological hurdles, since it won’t be supported by the two main smartphone operating systems, and has sparked concern among privacy campaigners.
