蘋果和谷歌聯手追蹤新冠患者

Apple and Google are partnering to help authorities track exposure to the coronavirus using Bluetooth technology.

蘋果和谷歌正在合作利用藍牙技術幫助當局追蹤冠狀病毒感染情況。

The two Silicon Valley giants will work on a platform to enable contact tracing, a measure that identifies people who have been exposed to the virus and who they have been in contact with, the companies announced.

這兩家硅谷巨頭公司稱，它們將在一個平臺上合作，啓用接觸追蹤，利用這種方法確認誰接觸過感染者，他們又接觸過誰。

The companies will first release interfaces built on existing public health apps in May that can work on iOS or Android systems, followed by a more comprehensive platform in the coming months to which users will be able to opt in.

兩家公司將於5月份首次推出建立在現有公共衛生應用程序上的接口程序，可以在iOS或安卓系統上運行，未來幾個月還會推出一個更復雜的平臺，用戶可以參與進來。

A smartphone user that tests positive for the coronavirus can input their result into an app from a public health authority, which will feed into an anonymous "identifier beacon," according to an explanation from Google. That identifier will then be anonymously exchanged with anyone the user comes into contact with who also has the service enabled.

谷歌解釋說，一位冠狀病毒檢測呈陽性的智能手機用戶可以在公共衛生當局的應用程序上輸入檢測結果，檢測結果會被添加進一個匿名的“標識符”。然後這個標識符會匿名交換給任何他接觸過並且也啓用了這一服務的人。

Users then upload their identifier records to the cloud, following which they will receive a notification if they have been exposed to anyone who has tested positive for the virus.

然後用戶將標識符記錄上傳到雲端，如果他們曾接觸過病毒檢測呈陽性的人就會收到通知。
