Abstract
Due to the development of technology, core technologies and information leakage of companies through mobile devices are increasing. Therefore, Various researches on electronic devices and IC elements protection technologies have been conducted. In the case of high frequency electromagnetic waves, it is harmful to the human body and damages electronic devices, making it difficult to apply them to real life. In this study, we investigated the characteristics of malfunction of shooting and recording function of smartphone near 20kHz which is audible frequency, not electromagnetic wave of high frequency band. Experimental results show that the camera is touched arbitrarily or the focus of the camera is changed. It can be applied to various industrial technology fields in the future.
