In response to the coronavirus (COVID-19) pandemic, Government and public health authorities around the world are developing contact tracing apps as a way to trace and slow the unfold of the virus. There is major divergence among nations, however, between a "privacy-first" approach that protects citizens' information at the price of very restricted access for public health authorities and a "data-first" approach that stores massive amounts of knowledge that, whereas of immeasurable price to epidemiologists. Contact tracing apps work by gathering information from people who have tested positive for the virus and so locating and notifying individuals with whom those people are in shut contact, oftentimes by use of GPS, Bluetooth, or wireless technology. All of the user's information is employed and picked up, the study found that users' information would be created anonymous, encrypted, secured, and can be transmitted on-line and stored solely in an aggregated format. Contact tracing apps use either a centralized or a decentralized approach to work the user's information. Apps that use a centralized approach have high privacy risks. In this paper, the researcher's contributions related to the security and privacy of Contact tracing apps have been discussed and, later research gaps have been identified with proposed solutions.
为应对冠状病毒（COVID-19）大流行，世界各国政府和公共卫生当局正在开发接触者追踪应用程序，作为追踪和减缓病毒传播的一种方式。然而，各国之间存在重大分歧，一种是以“隐私优先”为原则，以牺牲公共卫生当局非常有限的访问权限为代价来保护公民信息；另一种是“数据优先”原则，存储大量对流行病学家来说价值不可估量的知识。接触者追踪应用程序通过收集病毒检测呈阳性者的信息来定位并通知与这些人密切接触的个体，通常利用全球定位系统（GPS）、蓝牙或无线技术。该研究发现，用户的所有信息都被使用和收集，且用户信息将被匿名化、加密、安全处理，并能在线传输且仅以汇总格式存储。接触者追踪应用程序采用集中式或分散式方法来处理用户信息。采用集中式方法的应用程序存在较高的隐私风险。本文讨论了研究人员在接触者追踪应用程序的安全性和隐私方面的贡献，随后还确定了研究差距并提出了解决方案。
