The paper by Hong [1] presents a secure and light IoT protocol (SLIP) for antihacking. The proposed method introduces a number of typical applications such as the smart home, intelligent transportation, a security-issue analysis, and related convergence technologies for the realization of a secure IoT. Further, a comparison of the security issues between the IoT and the traditional network was performed, and it was concluded that the environment of the IoT-convergence system is a dangerous one with limited resources and fewer network guards. The paper by Li et al. [2] analyzes a study on the service and the trend of fintech security that is based on text mining. This study presents the tasks and directions of the fintech industry in consideration of the successful operation of fintech security through an analysis of the news articles from an online-data collection. The results contributed to a switching of the market awareness of fintech services and security in the present-day ongoing expansion of the fintech market.
