3 . Tech giants Apple and Google are teaming up to create a system that would let smart phone users know when they’ve come into contact with someone who has COVID-19.
The technology would rely on the Bluetooth signals that smart phones can both send out and receive. If a person tests positive (阳性) for COVID-19, they could inform public health authorities through an app. Those public heath apps would then warm anyone whose smart phones had come near the infected person’s phone in the previous 14 days. The technology could be used on both Google Android phones and Apple iPhones.
The companies insist that they will preserve smart phone users’ privacy and their technology will be used only by public health authorities to trace the spread of COV1D-19. Smart phone users can choose to use it. The software will not collect data on users’ physical locations or their personally identifiable information. People who test positive would remain unknown to the public, both to the people who came in contact with them and to Apple and Google. “Privacy is of greatest importance in this effort,” the companies said in a joint statement.
The American Civil Liberties Union has warned that using cellphone data to handle the pandemic carries risks of “destruction of privacy”. In a statement on Friday, ACLU cyber security counsel Jennifer Granick said, “The system also can’t work well if people don’t trust it”. She said that the joint Apple and Google project “appears to reduce the worst privacy risks, but there is still room for improvement.” She added that the contact tracing app should be used only for public health purposes and only for the duration of this pandemic.
Public health officials say the contact tracing — finding people who have been in contact with an infected person will be a key step in lifting shelter-in-place restrictions.
It would allow people who are known to have been exposed to the virus to isolate themselves, while letting others recover normal activities.
