IT devices such as the computer monitors, printers and copy machines radiate electromagnetic waves. If someone uses TEMPEST technologies, he or she can steal information on your computer monitor, a password from your keyboard, and information from you printer. The automatic cash dispensers, e-voting systems, and IC cards also contain potential risks. Receiving electromagnetic radiation  ・an antenna or a probe  ・a receiver　 Data processing 　・noise processing 　・abstraction of specified frequency Display of information 　・supplement information 　・reproduction of monitor information 　　 To block TEMPEST attack 　This group is researching and studying adequate means to protect infomation from  TEMPEST threats, and is conducting experimentation on monitoring in different conditions, and evaluation of existing anti-TEMPEST technologies.　 　TEMPEST experiment: Intercepting image on the notebook computer from 4 meters distance with an antenna and a receiver. 　TEMPEST experiment: Identify the informaition of the specified computer out of other running computers. 　Interception experiment from power cable.
