In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of functions in the present invention, and this may vary depending on the intentions or customs of the user, the operator, and the like. Therefore, definitions of these terms should be made based on the contents throughout this specification.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating a schematic configuration of an apparatus for preventing physical probing of a financial terminal according to an embodiment of the present invention; FIG.

Referring to FIG. 1, an apparatus 400 for preventing a physical probe of a financial terminal according to the present embodiment includes an MSR header 100, an information transmission medium 200, and a card reader module 300. The device 400 for preventing physical probe of the financial terminal can transmit a warning message by communicating with the external device 500 when a physical probe is detected by at least one of the configuration means 100 to 300.

The MSR header 100 is an element for reading the magnetic information of the card.

The card read module 300 receives the magnetic card information read through the MSR header 100 through the information transmission medium 200 (for example, a cable) to which the physical probe prevention function according to the present embodiment is added.

Although the MSR header 100 and the card read module 300 are shown separately for the sake of convenience, the MSR header 100 may be included in the card read module 300 to be implemented .

The MSR header 100 reads the magnetic card information using the magnetic sensor unit exposed in the front side (front side) (refer to FIG. 4A) and transmits the cable (i.e., information transmission medium) connected to the rear side And outputs the magnetic card information read through the magnetic sensor to the card read module 300. [ At this time, since the magnetic card information is not encrypted, information can be leaked by the physical probe.

The information transmission medium 200 internally includes a transmission line (i.e., a cable) for transmitting information (or data, control signals, etc.), and externally, a physical probe detection and prevention function Is added. That is, the information transmission medium 200 is formed by superimposing the upper and lower layers on the information transmission layer composed of a plurality of transmission lines (i.e., cables) with the physical probe detection and prevention layers (see FIG. 5).

At this time, the information transmission medium 200 is a kind of flexible cable, but it may be formed in the form of a flexible substrate.

The MSR header 100 may be connected to an electronic substrate (e.g., a printed circuit board) (not shown) to which the MSR header 100 is attached, Terminal (not shown) (see Fig. 4). The other longitudinal end of the information transmission medium 200 is connected to the card reader module 300 (see FIG. 2).

The connection terminal of the MSR header 100 or the electronic substrate (not shown) of the MSR header 100 are connected by the information transmission medium 200.

At this time, the rear surface of the MSR header 100 is bonded with a shielding material (e.g., epoxy) to prevent external exposure and physical probing (see FIG. 4B). That is, since the bonding is hardened in a solid state after a lapse of a predetermined time, the back surface of the information transmission medium 200 and the MSR header 100 are closely contacted to fix the physical probe.

The card read module 300 reads the magnetic card information read from the MSR header 100 and transmitted through the information transmission medium 200 or encrypts the specific information (e.g., card number, user information Etc.) to be transferred to a main board (not shown) or an external device 500 of the financial terminal.

The card reader module 300 reads and encrypts the smart card (or IC card) information or reads specific information (e.g., card number, user information, etc.) through arbitrary information processing, Or to the external device 500 via the network.

That is, the card read module 300 according to the present embodiment is an integrated module capable of integrally processing magnetic card information and IC card information.

The card read module 300 includes a plurality of electronic components (or electronic components) 310 mounted on an electronic substrate. Therefore, physical probing is possible through the lead wire (or connection terminal) of the electronic element (or electronic part) 310 exposed on the electronic substrate.

Therefore, in this embodiment, the electronic board of the card reader module 300 is formed of a multi-layer substrate, and a physical probe prevention function is added to the back surface of the electronic board to which the electronic element 310 is attached . A cover 360 having a function of preventing a physical probe is attached to a front surface (or an upper surface) of an electronic substrate to which the electronic device 310 is attached (see FIG. 2).

Accordingly, physical probing at any of the upper and lower portions of the card reader module 300 is prevented, thereby protecting information from being leaked.

In this embodiment, the description of the joining member and the joining method of the electronic board 320 and the cover 360 is omitted so as not to obscure the technical gist.

The cover 360 to which the physical probe prevention function is attached is coupled to the front surface FRONT (or the top surface) of the electronic substrate 320 of the card lead module 300, Arrangement of elements (or electronic components) and lead wires (or connection terminals) are prevented from being exposed to the outside, thereby preventing physical probing.

Also, the card reader module 300 may detect that the cover 360 is disengaged. The card reader module 300 adds a tamper switch 311 on the electronic board 320 to detect that the cover 360 is disengaged (see FIG. 2). The tamper switch 311 may be added to at least one arbitrary position (for example, an edge portion) of the electronic substrate 320.

The tamper switch 311 is a kind of contact switch which is operated when the engagement of the cover 360 coupled to the electronic board 320 of the card reader module 300 is released, The control unit 312 detects a change in the state of the tamper switch 311 to detect a physical probe attempt (see FIG. 2).

The control unit 312 of the card reader module 300 includes a MSR header 100 to which a physical probe detection and prevention function is added as described above, an information transmission medium 200, a card reader module 300, (E.g., an encryption key, a software integrity hash value, etc.) corresponding to a situation in which the probe attempt is detected when a physical probe attempt is detected from the cover 360 and the electronic boards 320 to 330 Destroys or deletes the external device 500 and outputs a warning message to the external device 500.

The external device 500 may be another financial terminal connected to the network, or may be at least one of a financial service server of an upper layer, a security server of a security company, or a warning device outputting an alarm.

FIG. 2 is an exemplary view for explaining an outer appearance of a device for preventing physical probing of a financial terminal according to an embodiment of the present invention, and FIG. 3 is a view for explaining a connection structure of the cover in more detail Fig.

As shown in FIG. 2, the device 400 for preventing physical probing of the financial terminal according to the present embodiment may include all of the card reader module 300 and may be formed therein.

The card read module 300 is composed of a plurality of electronic boards 320 and 330.

A plurality of electronic elements (or electronic components) 310 are mounted on the first electronic substrate 320 of the multilayer electronic boards 320 and 330. At least one second electronic substrate 330 is formed on the inner or rear surface of the first electronic substrate 320. The at least one second electronic substrate 330 is a pattern layer formed with a pattern.

A physical probe-preventing layer 340 is formed on the rear surface of the second electronic substrate 330.

The physical probing prevention layer 340 is a mesh layer made of an electronic mesh. However, since the mesh layer is a very thin film layer, the inner mesh structure can be seen through.

Accordingly, a film-shaped shielding layer 350 for visual shielding is formed on the rear surface of the mesh layer. For example, the shielding layer 350 may be formed of a copper material, but not limited thereto, and may be formed using another material having a visual shielding effect.

Since the electronic device 310 is mounted on the FRONT (or the upper surface) of the multilayer electronic boards 320 and 330 including the physical probing preventing layer 340 and the shielding layer 350, the physical probing preventing layer Layer) can not be formed. Thereby coupling the cover 360 to which the physical probe detection and prevention function is added. At this time, the height of the cover 360 to which the physical probe detection and prevention function is attached depends on the height of the internal electronic device 310, the slot for loading the card, the mounting position of the MSR header 100 mounted therein, 200 is prevented from being bent.

A mesh film 360b made of an electronic mesh for detecting and preventing a physical probe is formed on an inner surface (or an outer surface) of the cover 360 (see FIG. 3).

At this time, the cover 360 also functions as a case for protecting an IC card slot (not shown, mounted on the electronic board), and also functions as a card input port for inserting the IC card into the IC card slot And a mesh film 360b made of an electronic mesh for detecting and preventing a physical probe for the IC card slot is formed on an inner surface or an outer surface of the cover 360. [

3, the cover 360 is opened at one side so as to be coupled to the upper surface of the multilayer electronic substrate 320, 330 including the physical probing prevention layer 340 and the shielding layer 350, And a mesh film 360b attached to at least one side (inner side or outer side) of the housing 360. As shown in FIG.

A lead wire (not shown) of the mesh film 360b is connected to an arbitrary terminal of the control unit 312 of the card reader module 300 so that a state such as disconnection or short can be detected.

For example, the lead wire (not shown) of the mesh film 360b may be connected to an arbitrary terminal of the control unit 312 of the card lead module 300 through the tamper switch 311. Accordingly, when the cover 360 is disengaged, the controller 312 may immediately detect the state of the cover 360. Or when the cover 360 is disconnected by supplying power through the tamper switch 311, the power supply is automatically stopped so that the information stored in the volatile memory can be automatically deleted.

FIG. 4 is a diagram illustrating an exemplary combination of an MSR header and an information transmission medium in FIG. 1, FIG. 5 is a diagram illustrating an exemplary combination structure of an information transmission medium, .

4, the MSR header 100 reads magnetic card information through a magnetic sensor exposed on the front surface (FIG. 4A), fixes the magnetic sensor on the rear surface of the MSR header 100, (I.e., an information transmission medium) for transmission (Fig. 4 (b)).

5 is a cross-sectional view of a cable (i.e., an information transmission medium) for transmitting the information. The cable 220 for information transmission is disposed at an upper portion or a lower portion thereof with an electronic mesh The formed mesh films 210 and 230 may be formed.

In other words, the information transmission medium 200 includes an information transmission layer 220 formed with a plurality of transmission lines (i.e., patterns or cables) for transmitting information (or data, control signals, etc.) internally, Each of the physical probing preventing layers or sensing layers 210 and 230 (that is, the mesh film) is formed on or under the layer 220.

The physical anti-tampering or sensing layers 210 and 230 are formed of a mesh membrane in the form of a thin film (or film) composed of an electronic mesh.

At this time, the information transmission medium 200 may be formed of a flexible film cable such as a membrane cable, or may be formed as a flexible flexible substrate.

The MSR header 100 may be connected to an electronic substrate (e.g., a printed circuit board) (not shown) to which the MSR header 100 is attached, (Not shown), and the other end of the information transmission medium 200 is connected to the electronic board 320 of the card reader module 300.

Therefore, a film-like shielding layer (not shown) for visual shielding may be formed on the rear surface of the mesh layer, because the mesh layer can be seen through the mesh layer. For example, by adhering or coating (or applying) a film or paint of a material capable of being visually shielded.

FIG. 6 is an exemplary diagram showing a schematic internal structure of the card read module in FIG. 1;

6, the card lead module 300 according to the present embodiment includes a tamper switch 311, a controller 312, an MSR controller 313, an MSR connector 314, an IC controller 315, An IC slot 316, a battery 317, and a communication unit 318.

The tamper switch 311 is a switch for detecting that the cover 360 coupled to the board of the card reader module 300 is released as described above, The state of the tamper switch 311 is changed and the controller 312 detects that there is a physical probe attempt from a change in the state of the tamper switch 311.

The MSR controller 313 performs various processes on the read magnetic card information. For example, the magnetic card information may be encrypted or only specific information may be read.

The MSR connector 314 is a connection means for receiving the magnetic card information read from the MSR header 100 through the information transmission medium 200. At this time, until the card information read from the MSR header 100 is transmitted to the MSR controller 313, it is a plaintext communication interval. That is, the card information read from the MSR header 100 is plain text information that is not encrypted. Therefore, conventionally, there is a high possibility that card information is leaked by an external physical probe in the plain text communication section.

However, in this embodiment, in order to solve such a problem, card information read from the MSR header 100 is transmitted using the information transmission medium 200 to which the physical probe prevention function is added so that card information is leaked .

The IC controller 315 performs various processes on the IC card information read through the IC slot 316. For example, the IC card information can be encrypted or only specific information can be read.

The controller 312 monitors the state of the physical probe prevention function to detect whether there is a physical probe attempt from the outside. If a physical probe attempt is detected from the outside, the internal data (or program) is destroyed or deleted and a warning message is output to the external device 500.

The control unit 312 transmits the card information processed by the MSR controller 313 and the IC controller 315 to the external device 500 through the communication unit 318. [ At this time, since the card information processed through the MSR controller 313 and the IC controller 315 is encrypted information, the card information transmitted through the communication unit 318 is in a safe state even if it is leaked by the physical probe.

The battery 317 is a power source used for driving the card reader module 300 and monitoring the state of the physical probe prevention function.

The battery 317 is a power source used to hold an internal memory (e.g., a volatile memory) (not shown) in which internal data (or a program) of the card read module 300 is stored. Accordingly, when the battery 317 is removed, the internal data (or program) can be automatically deleted.

Also, the battery 317 performs an operation for destroying or deleting the internal data (or program) and transmitting a warning message to the external device 500 when the physical probe attempt is detected from the outside Or the like.

In the present embodiment, the physical probe prevention function is a means for detecting the presence or absence of a physical probe using an electronic mesh. When the mesh is partially broken due to a hole or a break in the mesh, . The mesh is formed in the form of a thin film or a film in which at least one or more electron lines are arranged at a very narrow interval. Therefore, when the film or the mesh in the form of a film is partially broken, the electron lines are easily broken.

At this time, the design in which the electron lines are arranged (i.e., the mesh structure) can be variously changed. The electronic line may be formed by using a general copper wire as a means through which the power of the battery 317 can be conducted, or may be formed by depositing an optional conductive material in the form of a thin film. Therefore, the electron line can be damaged (that is, short-circuited or short-circuited) when a voltage higher than a predetermined voltage (i.e., battery voltage) is applied.

As described above, according to the present embodiment, by covering the entire electronic board with a mesh, it is possible to protect each electronic device (or an electronic part), which had previously required individual security, at one time, (Eg, POS, subway, ID card terminal, etc.) other than the financial terminal can be easily applied by removing the internal data (or program) And it is possible to manufacture and sell a single module in the form of a module.

7 is a flowchart illustrating an operation of a device for preventing physical probing of a financial terminal according to an embodiment of the present invention.

7, in the apparatus for preventing physical probe of the financial terminal according to the present embodiment, the controller 312 of the card reader module 300 checks the mesh state using the power of the battery 317 (S101).

The MSR header 100, the information transmission medium 200, the cover 360 of the card reader module 300, and the electronic boards 320 to 350 ). ≪ / RTI >

The check of the mesh state may be performed periodically or at all times, and the check of the mesh state may detect a voltage, a current, or a resistance value of the battery 317, and check the mesh state using a change in the value have.

The controller 312 determines whether the mesh damage is detected through the check of the mesh state (S102).

If the damage of the mesh is detected according to the determination result (YES in S102), the control unit 312 destroys or deletes the internal data (or program) and transmits a warning message preset in the external device 500 (S103 ). At this time, the warning message may include information about the position where the physical probe is detected (i.e., the mesh where the physical probe is detected). As described above, the internal data (or program) is destroyed or deleted, thereby preventing leakage of important information (i.e., card information, user authentication information, device related information, encryption key, software integrity hash value, etc.).

If the damage of the mesh is not detected according to the determination result (NO in S102), the magnetic card information or IC card information is encrypted and transmitted to the external device 500 (S104). The encrypted card information is transmitted as described above, thereby protecting the card information.

It should be noted that the features of the inventions described above can be applied to each other even if they are described in other embodiments.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
