<p>The disclosure relates to a seal security device and system using fine particles having a random distribution. The security device and system are used for providing and applying a seal containing fine particles having a random arrangement to a room, a safe, a drawer, or the like requiring security where documents requiring secrecy maintenance to restrict an access is stored, scanning and storing the arrangement of the fine particles of the applied seal, and performing comparison on the stored arrangement of the fine particles when whether or not opening is performed is to be checked, thereby determining security depending on a match or a non-match. The seal security device and system provides device and system for determining whether or not secrecy is maintained for an entrance or products requiring secrecy maintenance, which includes control circuit, a device for detecting reflected signal light or magnetism, and a power supply device, and inspect the arrangement of fine particles by using a main body including an operating button unit for controlling security checking, a sensing unit which is formed at a lower end for detecting information on a seal, and a display window for displaying detection results of the sensing unit.</p> |
