Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a diagram schematically showing a system configuration diagram for terminal data transfer according to an embodiment of the present invention. 2 is a block diagram illustrating an internal structure of a terminal data transfer device according to an embodiment of the present invention.

1 and 2, the data transfer apparatus 100 is communicably connected to the source terminal 210 and the target terminal 220, and is communicably connected to the external server 250. [ Here, the source terminal 210 and the target terminal 220 include all personal mobile terminals such as mobile phones, feature phones, smart phones, and tablets. The data transfer apparatus 100 includes any device used for transferring data of a terminal such as a PC, a laptop computer, a workstation, and a server computer.

The data transfer apparatus 100 may be connected to the source terminal 210 and the target terminal 220 in a wired or wireless manner. For example, the data transfer apparatus 100 may be connected to the source terminal 210 and the target terminal 220 through a USB cable, or may be wirelessly connected via Bluetooth or Near Field Communication (NFC).

Also, the data transfer apparatus 100 can communicate with the source terminal 210 and the target terminal 220 using various communication methods. For example, the data transfer apparatus 100 may be connected to the source terminal 210 and the target terminal 220 via an ADB (Android Debug Bridge) communication, a USB communication, a modem communication, a port communication, a mobile disk communication, a Multicast Transport Protocol ) Communication.

The original terminal 210 represents a terminal that is the source of the data transfer, and the target terminal 220 represents the terminal that is the object of the data transfer. Although the models of the original terminal 210 and the target terminal 220 are different from each other, they may be the same type.

The data transfer apparatus 100 is provided with a data transfer program for performing the data transfer method shown in FIG. 3, and executes a data transfer program to convert the format of the original data of the source terminal 210 into the target data, (220). Wherein the source data and the destination data include at least one of an address book, a photograph, a text message, a call log, and an application list. Since the format of data is different for each model of each terminal, the original data and the target data have different format from each other. Therefore, the data escrow program of the data transfer apparatus 100 changes the format of the original data to the format of the target data.

Also, the data transfer apparatus 100 transmits the read result information of the original data to the external server 250.

2, the data transfer apparatus 100 includes a volatile storage unit 110, a non-volatile storage unit 120, and a control unit 130. [

The volatile storage unit 110 represents a storage medium for temporarily storing data for data processing, and specifically includes a random access memory (RAM), a cache memory, and the like.

The volatile storage unit 110 stores data in the form of data structure in a state where the data transfer apparatus 100 executes the data transfer program. Here, the data structure represents a concept in which the data escape program conceptually captures and stores the relationship existing between the data in terms of processing the data. The data structure is classified into a linear structure, a tree structure, and a network structure according to a reference relationship between data. The data structure is classified into a static data structure and a dynamic data structure depending on whether there is a change in structure or size during processing. In a static data structure, an array, a record structure or a book structure, . Most advanced programming languages tend to clearly define data structures as data types, particularly abstract data types that describe and describe the representation of data structures and manipulation procedures for them. Specifically, data structures may be represented by variable values within a class. For example, a method of realizing the data structure within the volatile storage 110 space is as follows. (1) A method of storing data in the memory space from the beginning to the end; (2) A method of distributing and storing data in a memory space in accordance with a distributed memory structure, and the like.

The original data represents data structure data having a data storage format of the source terminal 210 and the target data represents data structure data having a data storage format of the target terminal 220.

The volatile storage unit 110 stores the original data and the target data in respective data structures. In this case, the data structure is a data structure of a class type defined in the source code of the data escalation program. Specifically, the volatile storage unit 110 stores the original data as a variable value in a class corresponding to the source terminal 210, and stores the target data as a variable value in a class corresponding to the target terminal 220.

The nonvolatile storage unit 120 represents a storage medium for permanently storing data in the data transfer apparatus 100 in the form of a file. The nonvolatile storage unit 120 may be a hard disk drive (HDD), a solid state drive (SDD), a CD ROM drive, a DVD drive, a flash memory, or the like. The non-volatile storage unit 120 may store the encrypted original data and the encrypted object data.

The control unit 130 performs various functions of the data transfer apparatus 100, and in particular, executes the data transfer program to perform the data transfer method shown in FIG.

Hereinafter, the data transfer method will be described in detail with reference to FIG.

The data transfer apparatus 100 receives the data format related data format for each terminal type from the external server 250 at the first execution of the data transfer program and stores the data structure in the data structure inside the data transfer program at step S305. Specifically, the data transfer apparatus 100 receives data structures related to data formats corresponding to various types of terminals from the external server 250 at the time of initial execution of the data transfer program, Stored in the volatile storage unit 210 in the form of a data structure class.

The data transfer apparatus 100 confirms connection of the source terminal 210 and the target terminal 220 (S310). When the connection between the source terminal 210 and the target terminal 220 is confirmed, the data transfer apparatus 100 transmits the terminal device information of the connected source terminal 210 and the target terminal 220 to the pre- It is determined whether the device information is included in the data structure (S320).

Here, the device information of the terminal indicates information on a device (cell phone, printer, CDROM, USB memory, etc.) connected to the data transfer apparatus 100, and is information that can be confirmed through a device manager menu or the like. Specifically, the data transfer apparatus 100 includes a device PID (Product ID), a device VID (Vendor ID), a device PORT number (Port Number), a device INF File Name, device service name, and device version.

For example, a data structure for device information can be defined in the source code in a data escalation program in the following form:

class CMobileData

{

..

// variable

private:

CString str_Vid; // VID (Vendor ID)

CString str_Pid; // PID (Product ID)

CString str_PortRev; // Port Number

CString str_Inf [MAX_DEVICE_NUM]; // INF FileName

CString str_Service [MAX_DEVICE_SVC]; // Service Name

CString str_Version; // Service Version

int nComponentCount; // Device Count

int nStartComponentNum; // Start Device Count

CString nAnotherModel; // Another Model

int nAnotherModelCount; // Another Model Count

..

}

The data structure class for the device information of this type is stored in the volatile storage unit 110.

If the terminal device information of the connected source terminal 210 and the target terminal 220 is not the device information included in the previously stored data format related data structure for each terminal type (S320-N), the data transfer device 100 generates an error (S325), and then returns to the step S310.

If the terminal device information of the connected source terminal 210 and the target terminal 220 is the device information included in the previously stored data format related data structure for each terminal type (S320-Y), the data transfer apparatus 100 transmits, (Step S330). At this time, the data transfer apparatus 100 stores the original data in the volatile storage unit 110 in the form of a data structure. Specifically, the data transfer apparatus 100 stores the original data as a variable value in a class corresponding to the original terminal 210.

For example, the data structure of the data corresponding to the address book among the original data defined in the source code of the data escalation program is as follows.

class CAddressBook

{

public:

..

int addr_id; // AddressID

// BYTE code [5];

BYTE groupid; // GroupID

CString name; // Name

CString phonenum [5]; // Phone Number

WORD num_index [5];

CString shortnum [5]; // Short Number

CString email [3]; // EMail 1/2/3

CString memo; // Memo

BYTE addr_class [5]; // Address Class

CString birthday; // Birthday

BYTE prikey; // Primary Key

CString Address; // address

CString BDay; // Birthday date

CString BDayType; // Birthday Ms. Yang

};

In addition to the data structure of the address book as described above, the data structure of other original data may also be defined separately in the data evacuation program source code.

Then, the data transfer apparatus 100 converts the format of the original data into the target data (S340). Since the formats of data are different for each model of each terminal, the formats of the original data and the target data are different from each other. Therefore, the data escrow program of the data transfer apparatus 100 changes the format of the original data to the format of the target data. At this time, the data transfer apparatus 100 changes the data structure of the format corresponding to the original data to the data structure of the format corresponding to the object data in the state stored in the volatile storage unit 110.

Thereafter, the data transfer apparatus 100 stores the converted target data in the data structure (S350). Specifically, the data transfer apparatus 100 stores the target data as a variable value in a class corresponding to the target terminal.

Then, the data transfer apparatus 100 transmits the target data to the target terminal 220 (S360). Then, the target terminal 220 stores the target data in its own storage area.

Then, the data transfer apparatus 100 encrypts the original data and stores the encrypted data in the non-volatile storage unit 120 as a temporary file (S370). Since the data stored in the internal data structure is automatically discarded when the program is terminated, the data transfer apparatus 100 encrypts the original data using a cryptographic algorithm and stores the encrypted data in a temporary file. Stored temporary files can only be used for data escalation programs through the program.

Also, the data transfer apparatus 100 transfers the original data read result information to the external server (S380). Specifically, the data transfer apparatus 100 stores the original data read result information in the program internal data structure, and transmits the result to the external server 250 at the end of the data read / write operation. Here, the original data read result information includes at least one of the read time, the user ID, the mobile phone model, the operation type (read / write), the program version, and the number of read data.

An example of the data structure of the result information of reading the original data is as follows.

class CPhoneBook

{

public:

..

int gacnt; // Total number of groups

int gccnt; // Current number of groups

int acnt; // total number of contacts

int ccnt; // Current number of contacts

int cindex; // Current Index

int tindex; // Total Index

int maxindex; // Max Index

..

};

Thus, the data structure of the result information of the original data reading can be defined in the form of a class in the source code of the data escalation program.

Thereafter, the data transfer apparatus 100 displays a data transfer completion message on the screen (S390).

In this way, the data transfer apparatus 100 can convert the original data of the original terminal 210 into the target data format and transfer it to the target terminal 220. Therefore, the data transfer apparatus 100 transfers the internal data of the terminal within the data transfer apparatus, thereby minimizing the possibility of the leakage of the user's personal information.

It will be appreciated that the technical idea of the present invention can also be applied to a computer-readable recording medium having a data evacuation program installed in the data evacuation apparatus 100 according to the present embodiment to perform the data evacuation method. In addition, the technical idea according to various embodiments of the present invention may be embodied in computer-readable code form recorded on a computer-readable recording medium. The computer-readable recording medium is any data storage device that can be read by a computer and can store data. For example, the computer-readable recording medium may be a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical disk, a hard disk drive, or the like. In addition, the computer readable code or program stored in the computer readable recording medium may be transmitted through a network connected between the computers.

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 will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
