Description

Portable auxiliary memory with monitor and its data protection method

The present invention provides a means for connecting to a computer by wire or wirelessly, and includes a 'connecting unit' which is characterized by a function of exchanging data, and a 'data storage unit' which is a means of nonvolatile semiconductor memory. This is to increase the utility of this portable data storage device.

A computer, as illustrated in FIG. 1, generally includes a printer showing a result of processing information of the computer 100, an output device 101 such as a monitor, a RAM, a ROM, and the like, and is responsible for storing data. 'Input device 103' and 'output device' and 'storage device' characterized by means for inputting necessary information such as 'storage device 102', keyboard, camera, mouse, scanner, touch sensor, etc. And a 'central processing unit 104' which is responsible for the function control and calculation of the 'input device'. The above-mentioned

On the other hand, in the 'memory device', it is known that the RAM cannot maintain the stored data when the power supply is cut off, and the ROM cannot write any data, and the expansion of the storage capacity is not easy, and thus the 'secondary memory device ( It is common to supplement this using '

The auxiliary storage device includes a circular disk which is a rotating data storage means made of magnetic particles, and a mechanical header that reads data from or writes data to the disk. 'Hard Disk Drive (HDD)', which is characterized by being integrally configured with a 'driver', which is a feature that is fixed and used inside a computer due to the above-described structural features. It is easy to read and write a large amount of data including an application because of its high speed of reading and writing (106), but it is characterized by the purpose of repeatedly operating an operating system such as Windows, but using mechanical 'disk' and 'header'. It is known to be weak in shock or vibration due to the movement of 'and noise is generated. Recently, instead of the 'disk' and the mechanical 'header', a nonvolatile semiconductor such as a flash memory and an electrical 'controller' such as freely reading and writing and maintaining data stored without a power supply are used. As a 'semiconductor drive (SSD, Solid State Drive)' with an integral feature, there is a trend to replace a conventional HDD (see Patent Publications 10-0621631 and 10-0660546).

On the other hand, floppy disks are characterized by the arrangement of magnetic particles in plastic circular disks, and CD-ROM (CD) and optical disks are used to create physical grooves by optical methods such as lasers. Storage means such as 'DVD' and 'magnetic tape', which is characterized by changing the magnetization state of a tape composed of magnetic particles, are known in the art. Such storage means rotates the storage means to read or write data. There is a need for a separate 'driver' device that includes the ability to move and to read or write data stored on it. It will be referred to as a 'portable auxiliary memory device' which is different from the 'secondary memory device' such as the HDD or SSD having the characteristic of using.

On the other hand, the conventional 'portable auxiliary memory device' has low durability (CD, DVD, magnetic tape, floppy disk, etc.), difficult to repeatedly store data (CD, DVD, etc.), and the speed of reading and writing data is limited (self Tape, a floppy disk, etc.), and a data storage unit 203, which is characterized by a nonvolatile semiconductor (hereinafter referred to as a 'semiconductor memory') as described above in recent years, and wired or wireless to an external computer. The portable auxiliary storage device 110, which includes a connection unit 201 and a control unit 202, which provide a means for connecting and transmitting data to and from a computer, is widely used. (202) a procedure for recognizing and determining a signal exchanged through the connection unit 201 so as to connect the 'portable auxiliary memory device' to the external computer 110 by wire or wirelessly; In accordance with the present invention, the data storage unit 203 writes the data to the data storage unit 205 or reads the stored data to the data storage unit 203.

On the other hand, the above-mentioned 'output device', 'memory device' and 'input device' and the technology characterized by providing the connection means and data transmission between the computer, the power supply, signal exchange method with the computer, data transmission speed, etc. Therefore, Universal Serial Bus (USB), Personal System / 2 (PS / 2), Small Computer System Interface (SCSI), Integrated Drive Electronics (IDE), Advanced Technology Attachment (ATA), and IEEE 1394 are known. The connection terminal is simple and can supply driving power, and there is an advantage in that it is possible to simultaneously connect various convenience devices such as a mouse, a keyboard, a camera and a scanner with a simple operation, thereby supplementing or replacing the above-described techniques. In the case of USB 2.0 and USB 3.0, it surpasses the prior art (USB 1.1) transfer rate (5 million bits per second), up to 480 million bits and 5 billion bits per second, respectively. Are known to be transferred, is characterized by the use of 'portable auxiliary storage device "is a technique described in the USB' connection 201 '.

In particular, the 'portable auxiliary storage device' is similar in structure to the SSD described above, but unlike the 'portable auxiliary storage device', the 'driver' which acts as a 'controller' of the SSD is different from the 'portable auxiliary storage device'. And the control unit is characterized in that the control unit (202) is configured to respond to the request of the driver in accordance with the first procedure of connecting the 'portable auxiliary storage device' to the computer connection terminal. And a second procedure of recognizing a 'portable auxiliary storage device' as a removable storage device and a third procedure of 'driver' inside the computer preparing to exchange a signal with a control unit, which is the SSD. Not only is it a distinctive feature from its function, but it also enables the portable auxiliary storage device to be simplified and downsized, as well as portable. It will be. On the other hand, SSD, like the HDD described above, is used for repeatedly operating the operating system and applications such as Windows, and is directly fixed to a computer using high speed connection technology such as IDE and serial ATA, and recognized as a fixed storage device. Additional features such as the ability to process multiple 'semiconductor memories' in parallel to speed up reading and writing, and to manage unit storage areas with poor 'semiconductor memory' functions to improve the reliability of stored data. It is characterized by including a function, which is clearly distinguished from the 'portable auxiliary storage device', and is classified roughly into the 'secondary storage device' of the same class as the HDD.

On the other hand, due to the development of technology using a single substrate, integrated circuit technology and single chip integrated device technology, 'semiconductor memory' can be easily implemented to include various application functions other than storage functions, and compared to the standard storage capacity. The size of the component has been reduced, and accordingly, recently, a portable USB authentication device having an MP3 player and OTP (one-time password) random number generator having a functional feature of playing a sound source (see Patent Publication No. 10-0872901) ), It is also used as a storage device for various 'digital devices' such as digital cameras and mobile phones. Thus, when the 'digital device' is connected to a computer using the USB connection means provided with the 'digital device', the 'data storage' function of the 'portable auxiliary memory device' as the 'semiconductor memory' included in the 'digital device' Of course, the 'digital device' independently performs its original functions such as media playback, authentication, video recording, and telephony in a stand alone state regardless of computer connection. It is characterized by a self-running function, which is not only a cause for increasing the volume and size of the digital device, but also the original 'portable auxiliary memory device'. This is also clearly distinguished from 'data storage'.

Compared to the conventional 'portable auxiliary storage device' such as CD, DVD, magnetic tape, floppy disk, etc. described above, the 'portable auxiliary memory device' is able to repeatedly store data by using 'semiconductor memory'. Due to advances in electronic devices and semiconductor technology, miniaturization of the volume is advantageous. As a result, various shapes of rods, spheres, and the like are possible, and storage costs are known to be low. However, as repeated storage becomes possible, the loss of the 'portable auxiliary storage device' has a disadvantage in that it is vulnerable to security risks such as theft, unauthorized deletion and unauthorized changes of stored data.

It is a procedure to confirm the contents to the user by displaying the information on the screen, that is, a series of conversations between the 'portable auxiliary storage device' and the user, which can be directly used for user authentication of the 'portable auxiliary storage device'. Not only that, but also the conventional security means described above (see the Patent Publication 10-2009-0062199 to 10-2008-0085980, etc.) and the like can also be parallel.

On the other hand, the monitor is characterized in that the computer, TV, navigation devices, cameras, etc., to display the results of the operation or the information being performed on the screen in the form of charts, letters, numbers, the cathode ray and (CRT) , Plasma display (PDP), liquid crystal display (LCD), light emitting diode (LED), organic light emitting diode (OLED), etc., and features such as LCD, LED, OLED, etc. It is also widely used as a monitor for digital devices. On the other hand, the touch screen, a touch sensor that recognizes the contact with the monitor and converts it into an electrical signal, will be referred to as a monitor having a feature to include a function as an 'input device'.
