Apple-Google tech draws interest

Authorities in 23 countries across five continents have sought access to contact tracing technology from Apple and Alphabet’s Google, the companies announced as they released the initial version of their system.

But authorities would have to stop requiring phone numbers from users under the companies’ rules, one of several restrictions that have left governments fighting the novel coronavirus frustrated that the world’s top two smartphone software makers undercut the technology’s usefulness by prioritising user privacy.

Apple and Google said several US states and 22 countries have sought access to their technology, but it is unclear how many will end up publishing mobile apps that use it.

Using apps to accelerate contact tracing, in which authorities identify and test people who were recently near a virus carrier, has emerged as a tool to stem new outbreaks. It could help authorities test more potentially infected individuals than they would normally be able to based on patients recalling recent interactions from memory.

But some governments contend their app-based efforts would be more effective if they could track users’ locations to identify hot spots for virus transmission and notify them about possible exposure through calls or texts, rather than a generic push notification.

Apple and Google have barred authorities using their technology from collecting GPS location data or requiring users to enter personal data.

“We have a collision of tech, privacy and health professionals and the Venn diagram doesn’t really have a spot where they all overlap,” said Chester Wisniewski, a principal research scientist at cybersecurity company Sophos.

Australia, the United Kingdom and other countries that have sought to develop their own technology are experiencing glitches, draining device batteries and seeing limited adoption.
