To effectively prevent the spread of COVID-19 infections, contact tracing technology based on ICT technology is used and various types exist depending on the way they are tracked. However, these technologies are always exposed to security threats and each type of threat varies. In this paper, we identified processes that occur in common in various types of contact tracing technology and identified possible threats in this process. This resulted in a common evaluation criteria applicable to all types of contact tracing technologies and applied to actual published contact tracing technologies to perform comparative analysis by type. These studies can help select safe and effective contact tracing technologies through comparisons between different types.
