CEO of 谷歌, Mr Sundar Pichai has tweeted, “the two companies are committed to working together on these efforts”. Tim Cook, the CEO of Apple also tweeted that this new initiative made by the two companies will respect the consent and transparency of its users. In their 联合声明s the two CEOs have 说过 that “Since 新冠肺炎 can be transmitted through close proximity to affected individuals, public health officials have identified contact tracing as a valuable tool to help contain its spread. A number of leading public health authorities, universities, and NGOs around the world have been doing important work to develop opt-in contact tracing technology. To further this cause, Apple and 谷歌 will be launching a comprehensive solution that includes Application Programming Interfaces (APIs) and operating system-level technology to assist in enabling contact tracing. Given the urgent need, the plan is to implement this solution in two steps while maintaining strong protections around user privacy.”
的 two tech giants are currently working on an operating system-level technology and Application Programming Interfaces (APIs) in order to assist the health workers and officials in enabling the contact tracing. 的se APIs would help and allow Android and iOS devices to exchange information, and would further notify the health workers to keep track of the spreading of this deadly disease. So, once this feature comes into operation, whenever any two individuals would be near each other (or come in contact with each other), their phones will be exchanging an identification key and the users will get notification whether they have come into contact with any 新冠肺炎 infected person or not. 这个 would enable the users to either self-quarantine or get themselves tested. Also, if the user contracts the 新冠肺炎 virus, he can even notify the other person as well about it. 的 two companies have made sure that the privacy of their users is not breached and therefore, this application will be working without revealing the name of its users or any of their data. 的 person who got contracted with 新冠肺炎 will just be notified that he came in contact with a 新冠肺炎 infected person and nothing else. In fact, the location of the user will also not be traced by the devices.
谷歌 苹果强调他们不会聚集任何人’s exact 对抗小说的方向或坐标（或任何原因的数据） 新冠病毒。而是具有联系跟踪应用程序的小工具可以进行通信 定期向附近的各种小工具发出一种信号， 包括那些接近六英尺的物体，因为 六尺 是疾病中心提供的最小范围 社会隔离的控制和预防。
的 两家科技巨头也在他们的 联合声明 媒体说，“在未来的几个月中，苹果和谷歌 将致力于通过以下方式建立更广泛的基于蓝牙的联系人跟踪平台： 将此功能构建到基础平台中。这是更多 比API更强大的解决方案，如果 他们选择加入，并允许与更广泛的生态系统进行交互 应用程序和政府卫生部门。隐私，透明度和同意 在这项工作中至关重要，我们期待构建此功能 与感兴趣的利益相关者协商。我们将公开发布 有关我们工作的信息，供其他人分析。”
这个 倡议将分两个阶段进行。从现在开始的一个月后，Google和 苹果将发布其API，允许通过外部人员进行联系人跟踪 健康专家发布的应用程序。两种Android和iOS的用户 小工具可以通过各自的应用程序下载此应用程序 stores.
目前，用户愿意安装并向这些联系跟踪应用程序授予必要的权限，这些应用程序仍由基金会（例如，麻省理工学院的 私人自动联系人跟踪 (PACT). Also, it would be totally dependent upon the person to show on the off chance that they had gotten the infection, bringing about unknown alarms being sent to the individuals who had been in that individual’s contact. Disease transmission specialists and general health officials have as of late focused on Bluetooth innovation as an imperative instrument for human groups looking to follow and stem the pandemic’的发展。设计师说，这将补充人类接触追踪的努力，在此过程中，一般卫生官员将与个人进行交谈，以发现他们已经达到疾病发作时间或与之接触过。
的 接触追踪蓝牙规范 由Apple和Google共同开发，并且将进一步扩展和修改，因此不会使用其用户位置进行邻近检测，而仅限于蓝牙信标。 滚动接近标识符 of a user keeps on changing every 15 minutes and requires Daily Tracing Key to be related to its users which reduces its users’ risk of privacy loss and it totally depends on its users, to decide whether to contribute to contact tracing or not. 的 server will have the consent of the user to share their Diagnosis key if diagnosed with 新冠肺炎. Rolling Proximity Identifier of a user cannot be correlated without having the Daily Tracing Key. Thus, reducing the risk of privacy loss. A server operator that will be implementing this protocol will not learn who their users have been in contact with or their location until and unless users report their Diagnosis Keys without which it will be difficult for an attacker to search for a collision on Rolling Proximity Identifier. 这个 reporting will only be limited to 24hrs period. After the users have uploaded their Diagnosis Keys, the server must not be retaining any metadata of its users after including them into the aggregated list per day of its Diagnosis Keys.

罗恩·里维斯特, a famous cryptography expert and a PACT leader has already started some of the difficulties with such applications. It tends to be difficult to gauge go with Bluetooth and its results. Since such results will vary depending upon the manner in which the device is situated, regardless of whether it is tucked inside someone’s pocket or held against someone’s head for a call and the Bluetooth device apart from human beings also senses the walls, windows, and car doors, making it difficult to track the total number of 新冠肺炎 infected persons. Since the device will just be notifying its users that they came in contact with a COVID infected. 珍妮佛·格兰尼克（Jennifer Granick），网络安全顾问和ACLU监控， 说过 个人可能会相信这些框架，以确保他们确保安全，保持审慎并将信息存储在一个人身上’s小工具，不是任何集中式存储库。
