摘要：Automatic specimen polishing systems using IoT sensor technology are being developed to improve theefficiency of the passive metal polishing process. In the case of automatic specimen polishing systems usingIoT technology, a technique of analyzing and processing the data collected by sensors using a bitmap indexis used to process data at high speed. However, in order to perform remote control of IoT-based grinder, itis necessary to control access to shared resources, but existing systems are applying data processingtechnology that does not apply a method to cope with the security threat. Therefore, in this paper, wepropose a monitoring system that computes information collected from automatic specimen grinder by usingbitmap index by applying IoT layer security technology.
