A New Type Of Remote Control Mobile Hard Drive Designed To Self-destruct

Removable hard disk as an information storage areas typical portable carrier, often used to store military and defense areas classified information document, is widely used to store all kinds of information secret-level and above, while in the transport, transfer and other processes are stolen or accidentally lost events frequently occur, and how to protect the hard drive out of control of the stored data information security has become the core of secret work.Therefore, one can study in the event of an accident can destroy their own hard disk storage medium is necessary.First, this new anti-lost article is designed to self-destruct mobile hard disk theft and anti-loss wireless technology used in hard disk ranging through the use of PT2262 / PT2272 encoder and decoder with matching 315 MHz, 433 MHz wireless transmitter, receiver,real-time measurements within 200 meters of the distance between the hard disk and the handset. At the same time, the transmission frequency of 315 MHz wireless transmitter module and a receiver module supporting alarm systems were embedded in the hard disk and the handset, when the distance between two objects 100 to 150 meters, the remote control beep tablets power work to achieve the anti-loss alarm function; emission frequency of433 MHz transmitter and receiver modules detonation systems were installed in the remote controller and the hard disk, when the relative distance exceeds detonated explosive units threshold value of 150 meters, a hard disk connected via the decoder output high energize it exploded without manual operation, the storage medium- irreversibly destroying the disc,make it impossible to recover data from the residual fragments of data protection. Based on the equipment used, the paper means the overall structure and circuits were designed.Secondly, for the first time in order to generate explosive destructive conduct the disc irreversible physical damage. To determine the required dose, use LS-DYNA software basedCONWEP algorithm, the steel baffles and disk model, by applying a load of the disc in the form of an explosion, the explosion in the distance was 0.4cm, 0.5cm, disc materials are aluminum, glass, respectively 0.5 ~ 1.2g, 0.3 ~ 1.0g equivalent TNT equivalent of the eight groups, 32 groups were analyzed and compared model, derived from the explosion in 0.4cm,0.6g equivalent TNT equivalent under the glass substrate disk size blow up after all the debris has reached the area after the effective residual confidential data carrier exploded no more than 3mm * 3mm high standards; and the aluminum substrate disk burst from 0.4cm,equivalent TNT equivalent of 1.0 g, the structure was blown up all of its pieces have reached a state of its unrecoverable- aluminum Alloy material yield strength(plastic deformation greater than 0.20%). After the failure to blow up all the debris and can not recover the data,the data stored information played a protective effect, and with the baffle barrier does not harm the surrounding environment.Finally, the simulation results, depending on the material of the hard disk platters,glass disk substrates using equivalent TNT equivalent of 0.6g of electric detonator damage,while aluminum substrate disk is the equivalent of TNT equivalent of 1.0g electric detonators,and to install a low-pass filter in parallel TVS diode makes this device to achieve the self-destruct mechanism EED "three" requirements, and the installation of electric detonators location and size of the hard drive was designed.
