Contact Tracing is considered as the first and the most effective step towards containing an outbreak, as resources for mass testing and large quantity of vaccines are highly unlikely available for immediate utilization. Effective contact tracing can allow societies to reopen from lock-down even before availability of vaccines. The objective of mobile contact tracing is to speed up the manual interview based contact tracing process for containing an outbreak efficiently and quickly. In this article, we throw light on some of the issues and challenges pertaining to the adoption of mobile contact tracing solutions for fighting COVID-19. In essence, we proposed an Evaluation framework for mobile contact tracing solutions to determine their usability, feasibility, scalability and effectiveness. We evaluate some of the already proposed contact tracing solutions in light of our proposed framework. Furthermore, we present possible attacks that can be launched against contact tracing solutions along with their necessary countermeasures to thwart any possibility of such attacks.

接触者追踪被认为是遏制疫情的第一步也是最有效的一步，因为用于大规模检测和大量疫苗的资源极不可能立即使用。有效的接触者追踪可以让社会甚至在疫苗可用之前就从封锁中重新开放。移动接触者追踪的目的是加快基于人工访谈的接触者追踪过程，以高效、快速地控制疫情。在本文中，我们阐明了与采用移动接触者追踪解决方案对抗 COVID-19 相关的一些问题和挑战。从本质上讲，我们提出了一个移动接触者追踪解决方案的评估框架，以确定它们的可用性、可行性、可扩展性和有效性。我们根据我们提出的框架评估了一些已经提出的接触者追踪解决方案。此外，我们还提出了可以针对接触者追踪解决方案发起的可能攻击，以及阻止此类攻击的任何可能性的必要对策。
