Description

This invention relates to an information leakage suppression device, such as an information leakage suppression device for suppressing information leakage from a hard disk. In recent years, various countermeasures have been proposed to prevent the leakage of information stored on hard drives. While measures have been taken to prevent network intrusions into hard drives, a challenge remains in preventing information leakage from physical theft of computers, such as when a hard drive is stolen along with the computer, or when the computer is forcibly taken even after the theft is detected. For example, Patent Document 1 proposes a PC theft prevention system that utilizes the positional relationship between the PC main unit and peripheral devices to lock the hard drive installed in the PC main unit in the event of the PC main unit being stolen. Japanese Patent Publication No. 2012-053815 This is a side view showing the internal structure inside the case of a personal computer equipped with an information leakage suppression device according to one embodiment of the present invention, with the side panel removed.This is a schematic perspective view of an information leakage prevention device according to one embodiment of the present invention.This is an exploded perspective view of an information leakage prevention device according to one embodiment of the present invention.This is a cross-sectional view of an information leakage suppression device according to one embodiment of the present invention, taken along the line IV-IV in Figure 1.This is a cross-sectional view of an information leakage suppression device according to one embodiment of the present invention, taken along the line V-V in Figure 1.This figure shows the combustion process in an information leakage suppression device according to one embodiment of the present invention, as viewed along the line IV-IV in Figure 1, where the combustion section is burned to form holes in the first plate and the second plate.This is a block diagram showing the configuration of an information leakage prevention device according to one embodiment of the present invention. The following describes an information leakage suppression device 1 according to one embodiment of the present invention, with reference to the attached drawings. The embodiments described herein are illustrative and will be apparent to those skilled in the art that many modifications, changes, and substitutions are possible within the spirit and scope of the present invention. Therefore, the present invention is not limited to the embodiments disclosed, and various modifications, changes, etc., are possible in its form and details without departing from the claims. Furthermore, the components disclosed in the specification can be freely combined. As shown in Figure 1, an information leakage suppression device 1 according to one embodiment of the present invention can provide a device to suppress information leakage from a hard disk. The information leakage suppression device 1 also functions as a device that makes it difficult to read information from the platters of the hard disk so that the information in the hard disk 50 (see Figure 6) becomes unusable. For example, if the hard disk is about to be forcibly taken away along with the computer, or if it has been taken away, the information leakage suppression device 1 can create a path for introducing material from the housing to the hard disk by igniting explosives in a short period of a few seconds, making it difficult to read the information in the hard disk and thus suppressing information leakage from the hard disk. The hard disk 50 generally has the characteristic of being relatively hard and difficult to break even if one tries to destroy it physically, such as having the lower part of the hard disk case formed of die-cast aluminum. In the following description of one embodiment of the present invention, as shown in Figure 2, one longitudinal side of the information leakage suppression device 1 is referred to as the front, and the opposite side as the rear. When the information leakage suppression device 1 is facing forward, the right side is referred to as the right side, the left side as the left side, the upper side of the information leakage suppression device 1 is referred to as the upper side, and the lower side is referred to as the lower side. As shown in Figure 1, the information leakage suppression device 1 is placed inside the case 3 of a personal computer (PC) 2. The PC 2 is, for example, a stationary PC placed on an office desk. The case 3 is box-shaped; Figure 1 shows the case 3 with its side panel removed to reveal its internal structure. The PC 2 comprises a motherboard 6 on which the CPU and memory are located, a first power supply unit 7 that supplies power to the motherboard 6 and the hard disk 50 (see Figure 3), the hard disk 50, and the information leakage suppression device 1.
