苹果：Google，使用蓝牙的联系人跟踪：Android和iOS / API，将于5月发布
苹果和谷歌：
4月11日，该公司宣布将联合部署蓝牙解决方案以减少COVID-19大流行。
用户隐私和安全性是设计的核心。
世界领先的公共卫生当局，大学和非政府组织正在开发“选择加入的丰富的接触检测和跟踪技术”。
开发时间表：
第一步，五月发布了一个公共卫生官方应用程序，它是一个Android / iOS设备互操作性API。
以此为基础，我们旨在基于多种蓝牙实现丰富的触摸检测/平台。
该计划强调隐私，透明和同意。将来，我们将与相关各方协商，着重于此功能的开发。
将发布技术数据的草案版本，包括蓝牙和加密规范以及框架材料。

Apple, Google Alert to Coronavirus Exposure
The new system from the two tech giants addresses some of these worries.
It would rely on Bluetooth,
a technology that allows a device to communicate with other devices nearby.
If people choose to participate, their phones will keep a 14-day log of other devices they come into proximity with, whether that’s in a grocery store, on a bus, or along a city street.
Then, if someone tests positive for COVID-19 and chooses to report the result to a contact-tracing app, other users who crossed paths with that person in the past two weeks will be notified, so that they can get tested or self-isolate.
