Research on Automatic Search of Internet of Things in Big Data Era Based on Merge Sorting Method

As we enjoy these emerging technologies, we also face the risk of information being leaked. The information security problem has been plaguing us all the time. This is also the era of big data. Due to the continuous development of science and technology, the society has also caused the strong wind of the Internet of Things, and it is increasingly understood by ordinary consumers. As a consumer, it is necessary and necessary to understand the related security issues of the Internet of Things. According to this situation, this article makes a general analysis of the security holes in the Internet of Things, and proposes some prevention and control measures in light of the current network conditions. Based on the analysis of data processing of Internet of Things technology and logistics unified information system, and according to the characteristics of Internet of Things technology and unified information, an improved Shell ranking optimization algorithm in data processing of logistics unified information system is proposed.
