The USB memory 100, which is miniaturized and can be easily carried by a user, is suitable for storing and using data requiring security such as internet financial transactions and personal information.

The USB memory 100 is mainly used as an external computer. When the USB memory 100 is connected to the external computer, the USB memory 100 is gradually reduced in size. (100) are becoming increasingly dangerous.

Further, since the data stored in the USB memory 100 is data containing the privacy of the user, information about finance or the like requiring security, data leakage may cause secondary damage.

Therefore, the USB memory 100 requires a security function to protect data when it is inevitably lost, and a restoration function that can restore data is required.

The embodiment can prevent the loss of the USB memory 100 through the display of the USB memory 100 itself or the notification through the user smartphone when there is a risk of USB loss, And data loss prevention and data security features that enable users to restore data, such as by transferring data to a smartphone, transferring it to a Web server, or storing it on a connected computer. The USB memory 100 is provided.

1, the connector 120 corresponds to a port for interfacing with an external terminal 10 such as a computer.

The connector 120 may be directly connected to the body of the USB memory 100 or may be connected to the body of the USB memory 100 via a cable in the case of an external hard disk. The connector 120 allows the data transmitted from the external terminal 10 to be transmitted to the storage unit and the data of the storage unit to the external terminal 10.

The connector 120 can directly supply power supplied from the external terminal 10 to the USB display unit, the control unit 110 or the wireless communication unit 140, . Meanwhile, the USB memory 100 may have a separate power source, and may store power through the power source and transmit the power to the respective components. However, the present invention is not limited thereto.

The connector 120 may be fixed to the external terminal 10 according to circumstances. At this time, the fixing of the connector 120 means that the USB memory 100 can not be forcibly disconnected from the external terminal 10 by another user. For example, the connector 120 may be fixed to the external terminal 10 by inserting the latching portion inside the connector 120 and latching the latching portion inside the USB port of the external terminal 10.

However, the connector 120 may be separated when the latching portion receives a force exceeding the limit. At this time, the controller 110 recognizes the forced separation of the connector 120 and can format the data of the storage unit.

This fixing of the connector 120 can be released when user authentication is performed through the external terminal 10 or the user registered mobile terminal 20. [

The data transmitted and received through the connector 120 is stored in the storage unit 130. The storage unit 130 may store data transmitted from the external terminal 10 and the external terminal 10 may read the data stored in the storage unit 130.

Then, the notification unit 150 can inform the outside that it is a lost status. For example, the notification unit 150 may include an LED to indicate that the USB memory 100 is in a lost state by lighting the LED. Alternatively, the LED may indicate whether the USB memory 100 is connected to the external terminal 10 through the lighting color.

The notification unit 150 may include an audio output unit to inform the user that the USB memory 100 is lost.

Alternatively, when the notification unit 150 senses a loss situation, the notification unit 150 can notify the user of the lost status through the monitor or the speaker of the external terminal 10 through the connector 120. At this time, the notification unit 150 can display the previously stored loss contrast information on the monitor of the external terminal 10. In this case, the loss preparation information may be a cell phone number, personal information, and the like stored by the user in the storage unit.

Through these various notification methods, the risk of loss can be reduced by informing the user of the loss situation.

Meanwhile, the wireless communication unit 140 may interoperate the USB memory 100 and the user's mobile terminal 20. The wireless communication unit 140 may use the Bluetooth communication scheme, but is not limited thereto.

The wireless communication unit 140 may be paired with the mobile terminal 20 of a predetermined user when power is supplied. The wireless communication unit 140 may allow data of the storage unit to be transmitted and received only when the wireless communication unit 140 is paired with the mobile terminal 20 through the controller 110. [

That is, when the controller 110 confirms that the wireless communication unit 140 is paired with the user's mobile terminal 20, the control unit 110 can release the data security of the storage unit.

Then, the wireless communication unit 140 can confirm whether or not the mobile terminal 20 is continuously paired with the mobile terminal 20, and notify the controller 110 of the loss.

If the wireless communication unit 140 is not interworked with the mobile terminal 20 for a predetermined time or longer, the controller 110 determines that the USB memory 100 is lost, and proceeds to the lost state .

The reset button 160 may correspond to a button for releasing the mobile terminal 20 of a predetermined user. Alternatively, the reset button 160 may correspond to a button for canceling the pairing with the mobile terminal 20. [

The control unit 110 can control each configuration of the USB memory 100 described above.

The control unit 110 can recognize the situation through the connector 120 and the wireless communication unit 140 and operate according to a predetermined process to exert the data security, restoration and loss prevention function of the USB memory 100.

2 to 5 are flowcharts illustrating data security, restoration, and loss prevention processes of the USB memory 100 of the control unit 110 according to the embodiment.

2 is an initial flowchart showing a data security, restoration, and loss prevention process of the USB memory 100 of the control unit 110 according to the embodiment.

When the user connects the connector 120 of the USB memory 100 to the external terminal 10, power is supplied through the connector 120 so that the controller 110 can operate.

The control unit 110 attempts to pair with the mobile terminal 20 of the predetermined user through the wireless communication unit 140. [ (S101). When the pairing is performed, the controller 110 can release the lock of the storage unit and allow the storage unit and the external terminal 10 to transmit and receive data. If the pairing is not performed, the control unit 110 may maintain the lock in the storage unit. However, in order to use the USB memory 100 even when the user does not have the mobile terminal 20, the user can authenticate the external terminal 10 by inputting a password or the like and unlock the storage unit.

The control unit 110 may continuously attempt to access the user's mobile terminal 20 through the wireless communication unit 140 to confirm whether the pairing is maintained. (S103)

That is, when the pairing with the mobile terminal 20 is not maintained through the wireless communication unit 140, the controller 110 may determine that the USB memory 100 is in a lost state. (S200, S300, S400)

When the pairing is maintained, the controller 110 maintains the unlock state of the storage unit, and the storage unit can transmit and receive data to / from the external terminal 10 through the connector 120. [ (S105)

If the pairing is not maintained, the controller 110 notifies the user of the loss, stores the data so that the data can be recovered, and protects the data from other users.

Hereinafter, a method for a user to restore data in the USB memory 100 when the USB memory 100 is lost will be described.

FIG. 3 shows a flowchart for restoring data in the USB memory 100 according to the embodiment.

The control unit 110 may transmit the data of the storage unit to the user's mobile terminal 20 when the controller 110 determines that the data is lost. To the mobile terminal 20 of the user. If some data of the USB memory 100 is stored in the mobile terminal 20, only newly added data can be stored. That is, the controller 110 may synchronize the data of the storage unit with the mobile terminal 20 through the Internet network of the external terminal 10.

When the data can not be transmitted to the mobile terminal 20, the controller 110 may transmit the data of the storage unit to the predetermined web server. For example, data in the storage unit can be transmitted to a predetermined cloud server or a mail server. (S203)

The user can authenticate the user and connect to the cloud server or the mail server to restore the data of the storage unit.

Meanwhile, when data can not be transmitted to the mobile terminal 20 and data can not be transmitted to the web server, the controller 110 can store data in the external terminal 10 by encrypting the data. (S205)

The order of the data transmission to the mobile terminal 20, the data transmission to the web server, and the method of storing the encrypted data in the computer may be changed.

When the data can not be stored in the external terminal 10, the controller 110 may maintain the lock state of the storage unit and may not delete the data. (S207)

The controller 110 may delete the data when it is confirmed that data is transmitted to the mobile terminal 20, data is transmitted to the web server, or data is encrypted by being encrypted in the computer. (S209)

Thus, according to the embodiment, the user can recover data even if the USB memory 100 is lost.

Hereinafter, a method for protecting data in the USB memory 100 when the USB memory 100 is lost will be described. (S300)

FIG. 4 shows a flowchart for data protection of the USB memory 100 according to the embodiment.

First, when the controller 110 recognizes that the USB memory 100 is in a lost state through the wireless communication unit 140, the control unit 110 may lock the data transmission / reception of the storage unit. (S301). For example, the control unit 110 may disconnect access to the storage unit data by disconnecting the connector 120 from the terminal. Alternatively, the control unit 110 may disconnect data from the storage unit by disconnecting the storage unit from the connector 120. [

The controller 110 controls the external terminal 10 to prevent access to the data stored in the storage unit. (S303) For example, when the controller 110 recognizes that the terminal is in a lost state, the control unit 110 may display the preset loss contrast information on the monitor of the external terminal 10 and maintain a locked state that does not respond to the input to the interface. Alternatively, the controller 110 may block access to the data stored in the storage unit by interrupting the input of a mouse, a keyboard, etc. of the external terminal 10.

Meanwhile, the controller 110 may operate the latching portion of the connector 120 to fix the USB memory 100 to the USB port of the external terminal 10. (S305) When another user intends to forcibly remove the USB memory 100, the latching portion may be caught in the USB port.

In order to prevent damage to the USB port of the external terminal 10, when the USB memory 100 is subjected to a predetermined force or more, the latch of the latch can be released. At this time, the controller 110 recognizes that the USB memory 100 has been stolen by another user, and can format the data of the storage unit. (S307)

Hereinafter, a method of informing the user of the lost status when the USB memory 100 is lost will be described. (S400)

5 is a flowchart showing a lost state of the USB memory 100 according to the embodiment.

First, when the controller 110 recognizes that the USB memory 100 is in a lost state through the wireless communication unit 140, the controller 110 may notify the USB memory 100 that the USB memory 100 is in a lost state. For example, the controller 110 may turn on the LED included in the notification unit 150 to inform the outside that the LED is in a lost state. (S401). Alternatively, the controller 110 may output sound through the sound output unit included in the notification unit 150 to inform the outside that the sound is lost. (S403)

The controller 110 can notify the USB memory 100 that the USB memory 100 is lost through the external terminal 10. (S405). For example, the control unit 110 may output the loss contrast information stored in the storage unit through the monitor of the external terminal 10 to notify the lost status of the USB memory 100 to the outside. At this time, the lost information may correspond to the number and address of the mobile terminal 20 stored in the storage unit by the user.

The controller 110 may notify the USB memory 100 that the USB memory 100 is lost through the speaker of the external terminal 10. Alternatively, the controller 110 may transmit a signal to the user's mobile terminal 20 through the Internet network of the external terminal 10 to inform the user that the USB memory 100 is in a lost state. At this time, the controller 110 may inform the information of the external terminal 10 together. For example, the name of the external terminal 10 or the Internet port information to which the external terminal 10 is connected may be informed to inform the user of the lost location. (S407)

When the pairing with the wireless communication unit 140 of the USB memory 100 is canceled, the mobile terminal 20 can notify the user of the lost state through a pop-up window, sound or vibration.

According to the embodiments of the present invention described above, it is possible to prevent loss of the USB memory, prevent data leakage even if it is lost, prevent secondary damage, and further restore data.
