Description

[0001] The present invention relates generally to flash memory, and more particularly,

[0001] The present invention relates to a composite apparatus for security processing including data of a flash memory disk used in a solid-state drive (SSD), and more particularly to a dual- Function and a function of a defogger that completely disables the function of the laser and the SSD disk.

The title of the present invention, entitled "Hard Disk Drive (HDD) Hard Disk Drive ", which is a composite apparatus in which data of a hard disk is securely processed, is disclosed in Korean Patent No. 10-1684670 (registered on December 2, 2016) Discloses a laser and a device that functions as a degausser. The disclosure of this patent is hereby incorporated herein by reference.

When financial information, public institutions, or corporations bring out the important information stored in the hard disk to the outside without being completely deleted (dispose, return and sell), it causes social and national problems, and since December 2005, It is mandatory to delete such information. Accordingly, in the present hard disk supplement market, a laser which can logically erase data of a hard disk and reuse it is used, and a digger which physically makes the hard disk completely unusable is used.

According to the present invention, there is provided an apparatus for removing personal data of a hard disk according to the present invention, comprising: a substrate; a connector extending from the substrate; A first function coupled to the board for recognizing a connection state of an external hard disk drive, a second function for removing data of the connected external hard disk drive, a second function for inputting a fixed value to the external hard disk drive, And a fourth function for inputting the random number in an infinite overwriting manner, and is configured to make the recovery of the deleted personal data impossible, whereby the hard disk The drive can be easily recycled, and leakage of personal information can be blocked at the source.

In addition, in Patent Publication No. 10-2007-0032764 (2007.02.22), which is an example of prior art relating to a digzer, the present invention uses an external magnetic field to record the data area of one or a plurality of magnetic recording media in the magnetic recording device, And a permanent magnet of the drive motor in the case of a magnetic recording device driven by a drive motor. The present invention relates to a magnetic recording and reproducing apparatus and a magnetic recording and reproducing apparatus, which are capable of processing various types of magnetic recording devices, are highly susceptible to information erasing efficiency by directly exposing magnetic recording media to an external magnetic field physically, And is not influenced by the number of magnetic recording media.

The present invention makes it possible to erase all the data in the data area by inserting the magnetic recording media in various cases of the magnetic recording device into a place where strong magnetic force is applied without disassembling the case. In addition, the system area of the recording medium and the hard disk drive can completely destroy the track and sector delimiter. Further, in the case of a magnetic recording device operated by a drive motor, the permanent magnet of the drive motor is caused to be an element, thereby causing the motor function to be lost. Thereby causing the information storage function to be completely lost in the magnetic recording device. A magnetic circuit is implemented with the most efficient structure capable of generating a magnetic field using a permanent magnet so as to provide a leakage magnetic field intensively to the magnetic recording medium. The external magnetic field generated by the magnetic circuit is configured to be exposed directly to the front surface of the magnetic recording device.

FIG. 1 corresponds to FIG. 4 of Patent Publication No. 10-2007-0032764, and shows a diagram of a data erasing mechanism 400 of a first invention for implementing a data erasing technique. The data permanent erase mechanism 400 is composed of a magnet fixing part 401 at the upper part, a lower part magnet fixing part 403, and a connection part 402 connecting the upper part and the lower part to each other. The upper permanent magnets 410 and 411 are fixed to the upper magnet fixture 401 and the lower permanent magnets 420 and 421 are fixed to the lower magnet fixture 403 And the upper permanent magnets 410 and 411 and the lower permanent magnets 420 and 421 are arranged to have opposite polarities. The polarities of the upper and lower permanent magnets 410 and 411 may be reversed and the polarities of the lower permanent magnets 420 and 421 may be changed so that the upper permanent magnets 410 and 411 and the lower permanent magnets 410 and 411 The permanent magnets 420 and 421 may be aligned so as to have opposite polarities. The permanent magnets 410, 411, 420, and 421 are permanent magnets having the highest magnetic flux density, for example, Nd-Fe-B series permanent magnets. The upper and lower portions The connecting portion 402 for connecting the magnet 421 and the connecting portion 402 must also function as the magnet 410 and the magnet 411 and the magnet 420 and 421 on the lower portion. Therefore, the ferromagnetic material is used.

As described above, the basic technology related to this laser and the degausser has already been disclosed.

However, for security reasons, when the disc is processed by the software, that is, logically deleted by the software and the disc is recycled, the disc is not recognized by this laser due to the defect of the disc, And the data can not be erased by the software, so that the disc is sometimes completely discarded. Hereinafter, these discs are referred to as "bad disc ". However, some bad data on the bad disk often remain, so some data can be recovered. In this case, it may be contrary to the disk supplement and processing guidelines as described above. Therefore, it is necessary to degrade the disk so that the data can not be completely restored to these bad disks.

Therefore, in order to secure the disk, it is necessary to have two equipments of the laser and the digger, respectively, and to handle them separately. Therefore, in the computer room, the laser and the digzer are separately purchased and operated, resulting in economical / temporal waste and labor. Therefore, there is a need for equipment for fully erasing data and for handling defective disks in one device in batches.

In addition, it is not possible to manage what kind of disc is discarded because it is used only for the purpose of discarding a conventional defoaming apparatus. Therefore, it is necessary to scan the information of the bad disk to the mobile and collect logs and manage them on their programs.

To mount the disk to the server or storage, a guide is screwed to the side of the disk and the guide is fixed to the server or storage. Normally, when detaching a disk from a server or storage, the guide is still mounted on the disk. Conventionally, in this laser, a guide is separated and only a disk is mounted in a slot, and a data terminal and a power terminal are connected to each other. Such a separation operation makes the working time longer and inconvenient. The guide of the disk is made variously according to the server and the kind of the storage. Therefore, there is a need for a storage tray for storing disks capable of accommodating various types of disk guides.

Conventionally, in this laser, since data can not be permanently erased by one fiber disc, it is wastefully wasted due to degaussing. Therefore, it is necessary to completely erase and reproduce the data of the fiber disk to prevent the loss of industrial resources and to protect the customer's assets.

In addition, due to the speed and noise of hard disk drives (HDDs), data is stored using semiconductors, and the demand for fast, noise-free solid-state drives (SSDs) is increasing. However, in the case of HDD, there is still a demand because the data is kept for a long time and is very stable. Therefore, in recent years, by taking advantage of the advantages of these two drives, HDDs are often used as an auxiliary to the SSD in the main. In this case, equipment for erasing and / or degaussing the HDD and equipment for erasing and degaussing the SSD are separately required.

In addition, there is a growing demand for personal information security services related to flash memories related to smart phones, tablets, camera memories, SSDs, prevention of digital crime, various announcements and private organizations.

On the other hand, in the method of erasing a flash memory device of Korean Patent No. 10-0721623 (May 17, 2007, May 17, 2007), an electric field is formed between a substrate and a control gate and an erase pulse is supplied to move electrons of the floating gate toward the substrate Wherein the erase pulse is supplied in such a manner that the erase pulse initially supplied is gradually increased to a predetermined value and in the latter half of the erase operation a comparatively large erase pulse is supplied at equal intervals to erase the program , It is possible to shorten the time required for erasing and testing, and to lessen the influence due to the difference in erase speed between cells due to the difference in characteristics, and to prevent over-erasing, thereby improving the yield and productivity of the flash memory device.

In the security device for preventing the leakage of data information of the solid state drive (SSD) of Korean National Publication No. 10-2016-0129924 (public date: November 10, 2016), a user can directly destroy the flash memory by self- A data interface for data communication with a host; a data interface for communicating data between the flash memory and the host via the data interface; A controller for controlling a data exchange operation; and a buffer memory for temporarily storing data read from the flash memory and data to be written into the flash memory by the controller, in a solid state drive

In the flash memory, a wiring for allowing a high-voltage pulse to be applied to the source bias voltage terminal of the flash memory by bypassing the controller is provided, and a transistor junction of a cell of the flash memory is connected to the wiring by a user's switching And a high-voltage pulse generator for generating a high-voltage pulse to the extent that breakdown of the high-voltage pulse is generated and output to the wiring.

In addition, KCOM Co., Ltd. developed a digger that completely erases the HDD data and erases the data of SSD memory, SDHC card, USB memory and micro SDHC card. And is commercially available. In this case, there is a problem that the disk is physically completely destroyed using the magnetic force of 19,000 Gauss or more, and the SSD can not be reproduced.

The above-described prior art technique is to erase and degauss only the SSD, and it is necessary to separately purchase and use a device for erasing and degaussing HHD, which is widely used for secure data storage.

And these degausser products are the physical characteristics of the flash memory, making it impossible to erase the magnetic data. Therefore, it is only possible to physically dispose of them by the digzer. In this case, ASR is generated in the flash memory including heavy metals such as lead, mercury, cadmium, arsenic, and other environmental pollutants. And the economic losses are large due to discarding them.

Considering the necessity of the above-described conventional technology of the present invention, the HHD is a composite device capable of integrating a laser and SSD into a single device and locking and managing a work result using a mobile scan function ≪ / RTI >

Also, it is intended to provide a disk tray that can be used without detaching various disk guides in a combined apparatus.

Also, we want to provide software and hardware that can provide a hot swap function to continuously erase a disc without turning off the equipment when erasing various kinds of discs in a complex equipment.

In addition, it is an object of the present invention to provide an apparatus for physically reproducing or extinguishing a flash memory of a smart phone, an SSD disk, a tablet or a camera by using an electric field as a flash memory storage medium, and more particularly to an apparatus for physically erasing data in an SSD . In addition, we would like to provide an additional HDD size adapter that can be used for SSD to HDD docker.

It is also intended to provide a means for applying a voltage to the SSD to generate an additional electric field in SSD de-sizing.

The present invention relates to a laser for permanently erasing data from a disc using software, comprising: one or more trays for receiving the disc; a computer for driving the disc, identifying a bad state of the disc and erasing the disc; A laser connected to the substrate via a cable and comprising a flashing light indicative of a failure of the disk; A display connected to said laser for controlling and confirming the operation of said laser and displaying login information; A degausser which disposes a set of N-pole and S-pole permanent magnets capable of generating a magnetic force of 12,000 to 15,000 Gauss to face each other and inserts a hard disk therebetween, thereby completely disabling the hard disk; And a shielding film surrounding the permanent magnet so that the magnetic force of the permanent magnet does not exert any influence on the computer or the re-spinning disk, wherein the power is supplied and the voltage is controlled to recover the data of the SSD And a flashing lamp connected to the substrate of the computer by a cable and indicating a failure of the SSD disk, wherein the SSD includes a laser, And an adapter for enabling the disk to be used in the gateway. The display is connected to the SSD by the SSD to control and confirm the operation of the SSD emulator and display login information.

In addition, the shielding film is made of a special material so as not to damage the server or the human body in order to prevent damage to the hard disk, memory, and board inside the server, The shielding film comprises a high permeability disk-shaped metal or zinc special alloy disposed between the permanent magnets in one preferred embodiment.

In addition, the manufacturer provides the computer with a hot-swap capability that can be supported by software programs, even if the disks themselves do not essentially support hot-swap.

In addition, it provides an erasure function of the SAN / NAS / DAS storage connected to the computer with the cable.

In addition, it includes a mobile device capable of communicating with the computer to provide log collection and statistics of the disk.

In addition, the tray has a laterally slidable side so as to have sufficient space to accommodate a hard disk with various guides in the preferred embodiment.

The laser and the DIGAU are installed at the same time in one complex equipment, so that the purchase cost of the equipment can be lowered, the work can be made convenient, and the computer operation management can be efficiently performed.

It is possible to process both erasing and de-guarding of a hard disk and an SSD disk with one combined apparatus of the present invention, thereby lowering the purchase cost of the apparatus, Computer operation management can be done efficiently.

In order to prevent the economic damage caused by leakage of confidential data of an individual and an enterprise, it is necessary to erase information data of individuals and companies existing in various storage media, or to perform security processing of a disk including de- And these discs can be reproduced and reused, thereby reducing environmental and economic losses.

The present invention will now be described more fully with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with one embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

First, the SSD disk and the HDD disk will look exactly the same, and the way they are used is the same, which looks the same on an SSD disk or an HDD disk on Windows, same. However, SSDs and HDDs are hardware devices that are completely different. For example, HDDs are mechanical devices that use magnetic fields to store data, whereas SSDs are electrical devices that use floating gate transistors for data storage And the physical structure of the HDD has a structure in which a platter is divided into a cylinder, a track, and a sector, whereas an SSD has a block-and-page-based structure on a chip-by-chip basis. The physical structure of the SSD includes a control gate (CG), a floating gate (FG), an oxide film, a P layer, a drain and a source. When a voltage is applied to the control gate to fill electrons in the floating gate (FG) The voltage is applied to the layer to erase the data by emptying the electrons from the floating gate. Then, voltage is applied from the source to the drain, and the data is read by measuring and analyzing the charge of the floating gate.

2 shows a front perspective view of the composite device 1 in which the laser 3, the degausser 6 and the SSD are laser 50 (here, simply, the eraser means the HDD is a laser) at the same time. Referring to Fig. 2, the laser 3 includes at least one slot 2 for receiving a disk 5, and in Fig. 2, four slots are shown on the left. And a tray 4 on which the hard disk 5 can be seated and inserted into the slot. The main body of the eraser has a plurality of connectors for connecting the data terminal and the power terminal of the hard disk, and these connectors include various types of terminals (not shown) for connecting the terminals of various hard disks. The laser main body includes a computer for checking the state of the disk, erasing the disk, and checking the log. Also included in the array is a blinking light 16, which is connected to the computer board by cables and indicates a failure of the disk.

SSD This laser 50 includes at least one slot 52 for receiving a disk 55, and in FIG. 2, four slots are illustratively shown on the right. Each slot 52 has a tray 4 on which an SSD disk 55 can be seated and inserted into a slot. The main body of the SSD erasure device has a plurality of connectors for connecting the data terminal and the power terminal of the disc, and these connectors include various types of terminals (not shown) for connecting the terminals of various SSD discs. SSD This laser body includes a computer to check the status of the disk, erase the disk, and check the log. The SSD eraser also includes a blinking light 16, which is connected to the computer board by cable and indicates a bad check of the disc. As shown in FIG. 10A, in the case of the one-stage security state, the voltage of the voltage section that can be restored to the drain and source of the SSD through the power source connected to the terminal of the SSD disk is set to, for example, about 1 to 7 V To block access to data by thermal deformation effect. In this case, the SSD can be recovered and recovered. In the case of the two-step security state, a strong voltage is applied to the source and the drain of the SSD disk, and a voltage of 7 V or more, for example, as shown in FIG. In this case, since the SSD is physically damaged, it can not be reproduced anymore. These tasks are controlled by the computer's controller.

Figure 3a is a perspective view of the disc 5 placed on the tray 4 of the present invention and the tray 4 is inserted into the slot 2 shown in Figure 3d and connected to the apparatus. Normally, a guide 15 is attached to the disk 5 and mounted on various servers and storage. In order to mount the disk 5 to various servers and storage, guides corresponding to these slots are required. Therefore, the sizes and shapes of the guides are different according to the type of server and storage. Even the size and shape of the hard disk differ depending on the needs of the maker of the hard disk or the customer. The tray 4 of the present invention is made in a size and shape that can be used in the complex equipment as it is without loosening the guide 15 attached to the disk 5. [ In the preferred embodiment, as shown in FIG. 3A, the tray is configured in an oval shape instead of a conventional rectangle. In this case, since the disk separated from the server and the storage can be installed in the existing server and the storage by rebooting after the data is completely erased by the complex apparatus without disassembling the guide 15 attached thereto, Time can be greatly reduced. Fig. 3D includes a trough 21 in which the tray 4 shown in Figs. 3A to 3C can be easily inserted and fixed. And guiding lines 22 and 23 for guiding the hard disk size-wise without a tray. When the disc is inserted along the guide lines 22 and 23, the contacts of the disc with the apparatus coincide with each other.

In a preferred embodiment, Figure 3b shows the tray 4 with the slidable sides 41,42 of the present invention. FIG. 3C shows a state in which the side of FIG. 3B is expanded. The side surfaces 41 and 42 are slidably engaged with the bottom surface 43 of the tray 4 and can be moved laterally and adjusted in accordance with the size of the disc. Therefore, although the illustration shows the disc without the guide 15, it can be mounted on the tray 4 even with the guide 15 attached.

4A is a perspective view of a disc 55 in which the SSD of the present invention is placed on a tray 4 used for a laser and the tray 4 is inserted into the slot 52 shown in FIG. Usually, a guide 15 is attached to the disk 55 and mounted on various servers and storage. In order to mount the disk 55 to various servers and storage, guides corresponding to these slots are required. Therefore, the sizes and shapes of the guides are different according to the type of server and storage. Even the size and shape of the SSD discs differ depending on the needs of the manufacturer or customer of the SSD disc. The tray 4 of the present invention is made in a size and shape that can be used in the composite apparatus as it is without loosening the guide 15 attached to the SSD disk 55. In a preferred embodiment, as shown in FIG. 4A, the tray is configured in an oval shape instead of a conventional rectangle. In this case, since the disk separated from the server and the storage can be installed in the existing server and the storage by rebooting after the data is completely erased by the complex apparatus without disassembling the guide 15 attached thereto, Time can be greatly reduced. 4D includes a trough 21 in which the tray 4 shown in Figs. 4A to 4C can be easily inserted and fixed. And guide lines 22, 23 for guiding the SSD disk by size without a tray. When the disc is inserted along the guide lines 22 and 23, the contacts of the disc with this apparatus coincide.

In a preferred embodiment, Figure 4b shows the tray 4 with the slidable sides 41,42 of the present invention. 4C shows a state in which the side of FIG. 4B is expanded. The side surfaces 41 and 42 are slidably engaged with the bottom surface 43 of the tray 4 and can be moved laterally and adjusted in accordance with the size of the disc. Therefore, although the illustration shows the disc without the guide 15, it can be mounted on the tray 4 even with the guide 15 attached.

Note that SSDs are actually smaller in size than HDDs, so even though they are shown to be the same size in the drawings, the trays and guides are tailored to the SSD disk.

 2, a slot 2 of the laser 3 of the composite apparatus 1 of the present invention and a digger 6 in which the SSD is placed between the slots 52 of the laser 50 . DiGa proposed that the N pole and S pole permanent magnet sets 11 and 12, which are able to generate magnetic force of 12,000 to 15,000 Gauss, are disposed opposite to each other and a space in which the disk 5 or the SSD disk 55 can be inserted therebetween Have. The shielding film 7, which can block the magnetic force lines of the permanent magnets, surrounds the permanent magnets. The shielding film is made of special material to prevent any damage to the memory or board of the internal hard disk or SSD disk inside the server while minimizing the external leakage magnetic property of the magnetic field to a proper value of 40 Gauss or less. Do. The shielding film comprises a high permeability disk-shaped metal or zinc special alloy disposed between the permanent magnets in one preferred embodiment. In a preferred embodiment, when the shielding metal having a high permeability is wrapped around the permanent magnet, the magnetic field is caught by the metal, so that it can not extend outward. It is desirable to replace the shielding metal after a certain period of time because the metal itself is magnetized for a long time and a magnetic field is generated. Referring to FIG. 5, the garage door 10 of DiGauze is shown, and the garage door is also made of a metal having high permeability. A handle 8 is provided on the front side of the door hatch 10 and a storage compartment 9 capable of housing the disk 5 is provided on the rear side. During the erasing operation, the door 10 is closed, and instead of the disk, a high permeability metal is mounted in a disk shape. Also, the magnetic force of the permanent magnet is connected to the permanent magnet so that the magnetic force is not affected by the erasing operation of the disk. The smaller the space between the permanent magnet sets 11 and 12, the stronger the magnetic force. Therefore, unlike this laser, the guide 15 is used separately here. The disk 5 is inserted into the compartment 9 and placed in the space between the permanent magnets to carry out the degassing. Therefore, various data remaining in the hard disk storage device are destroyed by the magnetic force of the strong permanent magnet, thereby eliminating the anxiety due to data leakage.

6 shows an adapter capable of accommodating various types of flash memory (smartphone, tablet, SSD), the size and appearance of the adapter 60 is substantially the same as the size and outwardness of the hard disk 5, And a space 62 into which a flash memory (smart phone, tablet, or SSD) is to be inserted. For example, a terminal of the SSD is inserted toward the open end 61, and this terminal is connected to the power source of the main body. Therefore, by using this adapter 60, various flash memories can be processed. When the SSD disk is inserted into the adapter 60 to be placed in the space between the permanent magnet sets 11 and 12, the performance of the semiconductor is destroyed by the magnetic force of the permanent magnet. Also, by applying a strong voltage to the P layer through the terminal of the SSD, a strong electric field can be generated in the P layer to destroy the memory cell.

Next, referring to FIG. 7, the complex equipment, the complex equipment, the switch, and the storage are shown. The mobile will scan and collect the information recorded on the referenced disk, for example barcode, Q-code or recorded information, and automatically input it to the computer of this multifunction device. Also, the statistics of the data stored in this multifunction device Manage, and query the data. In addition, this combined device can recognize each disk installed in SAN / DAS / NAS storage via switch (SW) of all kinds of SAN / DAS / NAS and erase function to completely erase data.

FIG. 8 shows a data deletion detail report for log confirmation. In this report, deletion information, hardware information, and other information can be input and managed.

Next, how to operate will be briefly explained.

First, the information of the collected disc is input to the composite apparatus using the mobile and the desired data is input by using the keyboard. Next, put the disc in the tray, insert it into the slot, connect the terminals of the disc to the terminals of this multi-function device to check whether the disc is defective. For example, if the disc is recyclable, blue blinking light will come in. Come in. This information is input to the composite equipment, the discs that are recyclable are left as they are, and discs with red blinking lights are not recyclable, so disconnect the connection terminals and remove them from the slot. Then, the remaining data is completely overwritten by overwriting the entire data in the disc several times with data streams such as data, streams, special characters, and the like generated through an internationally verified algorithm to completely delete the existing data. A report such as this one is displayed on the display so that the operator can check it. After this erasure, the disc is reusable. A hot swap function is provided so that an additional disk can be inserted into an empty slot in addition to the slot during the erasing operation of the disk so that the additional disk can be continuously operated according to the operation sequence. In this way, work efficiency can be improved.

In a preferred embodiment of the present invention, a computer provides a hot-swap function that can be supported by a software program, even if the manufacturer does not essentially support hot-swapping on the disc itself.

In the same way, each disk installed in the SAN / DAS / NAS storage can be recognized via the switch (SW) of the SAN / DAS / NAS to judge whether it is defective, and the data of the disk can be completely erased.

Next, since the disk with the red blinking light is not recyclable, it is necessary to separate the connection terminals from the slot, complete the erasing operation, cut off the erasing power, insert it into the compartment of the digger, To completely destroy the data, as well as to make the disk non-recyclable. When DiGauzer finishes this task, DiGeorge's blinker lights up. The information on the disk on which de-gaming has been completed is displayed on the display as a report as shown in Fig. 9 so that the operator can confirm it.

As described above, the combined apparatus capable of processing both erasing and degaussing of the disk of the present invention includes a function of completely defogging the defective disk by inserting the defective disk into the blade, the function of checking the defective disk, It has the function to record and log the result, the function to save the result of the self-employment as a log file, the date, the time, the deletion method, the serial confirmation function of the disk and the report- , It is possible to lower the purchase cost of the equipment, make the work convenient, and efficiently manage the operation of the computer.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
