Description

[0001] METHOD AND APPARATUS FOR PREVENTING OF TAPPING [0002]

The present invention relates to the field of telephones and, more particularly, to a method and apparatus for preventing eavesdropping and eavesdropping using Internet telephones connected to a network.

Since the Internet telephone is connected to the Internet, it is convenient to remotely manage and control it. On the other hand, it is easily exposed to the outside, and the Internet intruder intrudes into the Internet phone through the network and executes the CPU (Central Processing Unit) (Digital Signal Processor), codec (codec: decoder) and so on, or is exposed to the risk of tapping using a microphone included in the Internet telephone. Since the microphone is always connected to the codec in the Internet telephone, the voice data formed by acquiring the voice signal from the microphone can be introduced into the codec. Accordingly, the Internet intruder can control the CPU, the DSP, and the codec to transmit voice data to a desired IP address, analyze the voice data, and intercept the voice signal acquired through the Internet telephone.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions will not be described in detail if they obscure the subject matter of the present invention. In the drawings, the same reference numerals are assigned to the components having the same configuration and function, and a detailed description thereof will be omitted.

FIG. 1 is an exemplary view showing a configuration of a telephone set according to an embodiment of the present invention.

1, the telephone 100 may include a microphone 110, a switching unit 120, a display unit 130, and a communication line CW having a path for performing a call. In one embodiment, the microphone 110, the switching unit 120, and the display unit 130 may be connected to each other using a communication line CW. In one embodiment, the eavesdropping prevention device may be included in the telephone 100 or may be provided separately from the telephone 100, including the switching unit 120 and the display unit 130. [

The microphone 110 can convert a sound signal such as a human voice into an electrical signal. In one embodiment, the microphone 110 may include a hands free microphone or a handset microphone included in the handset of the telephone.

The switching unit 120 can physically connect or disconnect the communication line CW for performing communication using the electrical signal formed by the microphone 110 and the microphone 110. [ In one embodiment, the switching unit 120 includes a mechanical switch to allow a user to operate a speaker phone for use of a hands-free microphone or to turn on a hook switch to use a handset microphone The microphone 110 and the communication line CW can be physically connected.

The display unit 130 may indicate whether the microphone 110 is connected to the communication line in the form of sound or light. In one embodiment, the display unit 130 may include an LED (Light Emitting Diode), a chime bell, or the like, and may use an electrical signal formed by the microphone 110 when the microphone 110 and the communication line CW are connected And can stop driving when the connection between the microphone 110 and the communication line is released.

2 is a schematic circuit diagram of a telephone according to an embodiment of the present invention.

As shown in FIG. 2, the eavesdropping prevention apparatus 200 in the telephone 100 may be connected to the processor P through the switching units 120-1 and 120-2. The eavesdropping prevention device 200 may include a handsfree microphone 110-1 and a handset microphone 110-2 as a microphone 110 and may include a microphone for performing a call using a handsfree microphone as the switching unit 120 A first switching unit 120-1 physically connected to a hands-free button (not shown) and a second switching unit 120-2 physically connected to a hook switch (not shown) for making a call using the handset, And may include an LED 130-1 as the display unit 130. [

When the user of the telephone set 100 turns on the hands-free button for telephone conversation, the first switching unit 120-1 physically connected to the hands-free button operates so that the hands-free microphone 110-1 is connected to the first communication line CW- The second switching unit 120-2, which is physically connected to the hook switch, operates when the user turns on the hook switch by picking up the handset for telephone conversation, and the handset microphone 110 -2 may be connected to the processor P via the second communication line CW-2. In one embodiment, the processor P may include a central processing unit (CPU), a digital signal processor (DSP) for performing voice processing, a codec (codec) and the like.

The first switching unit 120-1 or the second switching unit 120-2 operates so that the handsfree microphone 110-1 or the handset microphone 110-2 is connected to the first communication line CW- When an electric signal formed in the hands-free microphone 110-1 or the handset microphone 110-2 is applied to the turn-on resistor R2 included in the display unit 130, the transistor (CW-2) A current generated from the power source V _CC is applied to the LED 130-1 through the resistor R1 and the transistor TR1 so that the LED 130-1 can emit light.
