Description

TECHNICAL FIELD [0001] The present invention relates to a portable memory security system,

The present invention relates to a mobile memory security system and method having security functions, and more particularly, to a mobile memory security system and method for activating a security module according to whether an activation signal is detected by communicating with a local wireless emitter.

In general, a removable memory device typified by a USB memory is a device that can be connected to a port of a computer to exchange and store data. In recent years, a memory using a USB port is mainly used in consideration of the convenience of automatic recognition. However, if necessary, a portable memory device may be considered in which a memory card or the like is connected to a communication port of a computer or the like.

However, since such a conventional mobile memory device has a standardized connection method, if a portable memory device is lost, the lost mobile memory can recognize and recognize data from any computer.

As a result, there has been a need for restrictions on the use of removable memory in places such as companies and laboratories where security data is frequently used.

To this end, a method for enabling the use of mobile memory only within a predetermined interval based on Bluetooth communication has been developed in the prior art No. 10-1445617.

However, according to the conventional technology, only a mobile memory can be controlled within a specific area because Bluetooth can only transmit and receive signals between a specific terminal and a specific mobile memory. Accordingly, although the prior art may be suitable for the personal use, there is a problem in that the use of the portable memories can not be controlled by the public facilities, the organization, the group, and the like.

In addition, since the mobile memory according to the related art operates only on the basis of the Bluetooth communication, there is a problem that the mobile memory can not be universally used under various usage environments.

FIG. 2 is a block diagram showing the configuration of a mobile memory security system according to the present invention, and FIG. 3 is a block diagram showing the configuration of a mobile memory according to the present invention.

Hereinafter, a specific embodiment of a mobile memory security system according to the present invention will be described in detail with reference to FIG.

As shown in FIG. 2, the mobile memory security system according to the present invention includes a local area wireless transmitter 100, a mobile memory 200, and a terminal 300.

First, the local wireless radiotelephone 100 transmits a specific signal within a short distance so that the mobile memory 200 can receive the signal.

The mobile memory 200 is connected to a mobile memory access interface of the terminal 300 and senses a signal from the local area wireless transmitter 100. To this end, A control unit 220, a security module 230, and a storage unit 240. [0033]

The receiving unit 210 receives a signal of the local area wireless radiotelephone 100 and transmits the signal received from the local area wireless radiator 100 to the controller 220. The controller 220 controls the security module 220, (230) is activated.

The control unit 220 determines whether the security module 230 is activated by determining whether the activation signal is sensed by the reception unit 210. If the security module 230 is activated, And the type of data input / output.

In this case, the security module 230 is a part for data security of the mobile memory 200. To this end, the security module 230 may include a power cutoff unit 232 or may be configured to include an encoding unit 234 And a decoding unit 236.

First, according to the first embodiment of the present invention, the security module 230 includes a power shutoff unit 232.

In this case, the power cut-off unit 232 is activated or deactivated according to whether the activation signal is detected. When the activation signal is detected, the power cutoff unit 232 is deactivated and supplies power to the storage unit. And is activated to cut off power to the storage unit.

According to the second embodiment of the present invention, the security module 230 includes an encoding unit 234 and a decoding unit 236. When an activation signal is detected And encrypts the save data transmitted from the terminal 300 with a unique key value included in the activation signal and transmits the encrypted save data to the storage unit 240.

The decoding unit 236 is activated when an activation signal is detected and decodes the load data to be transmitted from the storage unit 240 to the terminal 300 into a unique key value included in the activation signal .

If the activation signal is not detected, the encoding unit 234 and the decoding unit 236 are inactivated to store or read the data in the removable memory 200 without encrypting or decrypting the data.

For example, when the mobile memory 200 is used in the space where the activation signal is received, the encoded and stored data among the data stored in the storage unit 240 is decoded through the decoding unit 236 As shown in FIG.

However, in the case of unencoded data, the data modulated through the decoding unit 236 is provided, so that it can not be utilized on the terminal 300.

Conversely, when the mobile memory 200 is used in a space in which no activation signal is received, as the decoding unit 236 is deactivated, in the case of unencoded data, unencoded circular data is transmitted to the terminal 300 However, since the encoded and stored data is provided to the terminal 300 in a non-decoded state, the terminal 300 can not use the decoded data.

The terminal 300 is a device having a removable memory interface, and may be configured as a computer, a notebook computer, a tablet PC, or the like. The terminal 300 is connected to the portable memory 200 through a removable memory interface, .

Hereinafter, a first embodiment of a mobile memory security method according to the present invention will be described in detail with reference to FIG.

According to the first embodiment of the present invention, the security module 230 includes a power cutoff unit 232.

As shown in FIG. 4, the first embodiment of the mobile memory security method according to the present invention starts with detecting whether the removable memory 200 is connected to the mobile memory interface of the terminal 300 (S 110) .

At this time, when the mobile memory 200 is connected to the mobile memory interface, power is supplied through the mobile memory interface, and the mobile memory 200 activates the receiving unit 210 and the control unit 220 by the supplied power.

Thereafter, the activated receiving unit 210 of the mobile memory 200 determines whether the activation signal transmitted from the local area wireless radiator 100 is sensed (S130).

When the receiving unit 210 receives the activation signal, the control unit 220 deactivates the power cutoff unit 232 in step S140 and supplies power to the storage unit 240 so that the portable memory 200 (S150).

If the receiving unit 210 does not receive the activation signal, the control unit 220 activates the power cutoff unit 232 (S160) and turns off the power of the storage unit 240 so that the portable memory 200 (S170).

Of course, even when the storage unit 240 of the mobile memory 200 is inactivated, the receiving unit 210 and the control unit 220 of the mobile memory 200 remain activated, The power is supplied to the storage unit 240 at any time so that the portable memory 200 can be used.

Hereinafter, a second embodiment of the mobile memory security method according to the present invention will be described in detail with reference to FIG.

According to the second embodiment of the present invention, the security module 230 includes an encoding unit 234 and a decoding unit 236.

As shown in FIG. 5, the second embodiment of the mobile memory security method according to the present invention starts with detecting whether the removable memory 200 is connected to the mobile memory interface of the terminal 300 (S210 ).

Thereafter, the control unit 220 of the mobile memory 200 activates the receiving unit 210 (S220) and determines whether the signal transmitted from the local area wireless radiator 100 is sensed (S230).

When the receiver 210 receives the activation signal, the controller 220 calculates a unique key value from the received activation signal at step S240 and activates the encoding unit 234 and the decoding unit 236 S250).

When receiving a data read request signal from the terminal 300, the load data is read from the storage unit 240 (S260), the load data is decoded into the previously calculated unique key value (S270) And transmits the load data to the terminal 300 (S280).

When receiving a data storage request signal from the terminal 300, the terminal 300 receives the save data from the terminal 300 (S290), encrypts the save data with the unique key value (S300), and transmits the encrypted save data And stores it in the storage unit 240 (S310).

If the receiving unit 210 does not receive the activation signal, the control unit 220 deactivates the encoding unit 234 and the decoding unit 236 (S320) The data is stored and read (S330).

Accordingly, the use of the stored and read data is limited depending on the type of the activation signal and whether or not the activation signal is received.

For example, when data is stored in the first activation signal state and data is read in the second activation signal state, the data encoded and stored as the unique key value of the first activation signal is stored as the unique key value And is provided to the terminal 300, so that the data can not be used.

When data is stored in the first activation signal state and data is read in the absence of the activation signal, the data encoded in the unique key value of the first activation signal is stored in the terminal 300 in a state that the stored data is not decrypted. So that the terminal 300 can not use the provided data.

Similarly, when data is stored in the absence of the activation signal and data is read out in the first activation signal state, the unencoded circular data is decoded to the unique key value of the first activation signal and provided to the terminal 300 It can not be utilized on the terminal 300. [

It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the appended claims. It is self-evident.

The present invention relates to a mobile memory security system and method having security functions, and more particularly, to a mobile memory security system and method for activating a security module according to whether an activation signal is detected by communicating with a local wireless emitter, According to the present invention, it is possible to control the activation and deactivation of the mobile memory according to receipt of an activation signal provided in a specific area, thereby controlling activation of a plurality of mobile memories in the corresponding area.
