Abstract

A computer hard disk self-destruction device based on double protection and its self-destruction method. The device includes blasting charges, a box body and a switch controller for reading the password of the computer hard disk. There are multiple grooves for placing explosive charges on the side of the box body and the disk adjacent to each other. The legs of the blasting charges in the same box are connected in series, and the legs of the blasting charges in different boxes are connected in series. The wires are connected in parallel with each other, and the two ends of the foot wires connected in parallel are connected in series with the power supply of the computer hard disk through a switch to form a closed circuit. When the device fails to read the password of the computer hard disk, the switch controller controls the switch to be in the closed state, detonating the blasting charge, and the high explosion heat and acid corrosion cause the hard disk to be destroyed. The invention can apply double destruction protection functions of high explosive heat and strong acid corrosion to the computer hard disk, and completely destroy the computer hard disk and the stored data.

Description

technical field [0001] The invention relates to the field of safety engineering, in particular to a computer hard disk self-destruction device based on double protection and a self-destruction method thereof. Background technique [0002] With the rapid development of information, information leakage incidents have increased. In consideration of information security, financial, securities, government, enterprises and other institutions have daily storage of sensitive data secret files, confidential files, a large number of user data, other sensitive data and other carrier hard drives , floppy disk, U disk, CD, etc. use certain technical means to destroy data, especially in the military industry and other secret-related departments have special regulations and requirements for the destruction of computer hard disks. The invention patent with the patent number of 201210030309.6 provides a method for destroying computer hard disk data by a pulse circuit, and the invention paten...
