Abstract

A device and a method for maintaining voice communication security in a terminal are provided, which enable the terminal to maintain security for a conversation during voice communication. The device includes a microphone for receiving voice data through a microphone in a voice communication mode; and a controller for making a control to decode encoded characters included in voice data received through a microphone in a voice communication mode, and then transmitting the decoded characters to a counterpart terminal communicating with the device.

Claims

1. A device for maintaining voice communication security in a terminal, the device comprising:

a microphone for receiving voice data through a microphone in a voice communication mode; and

a controller for making a control to decode encoded characters included in voice data received through a microphone in a voice communication mode, and then transmitting the decoded characters to a counterpart terminal communicating with the device.

2. The device as claimed in claim 1, wherein the controller converts a voice communication mode into a voice communication security maintaining mode in response to a specific user input in the voice communication mode, the decoder decodes encoded characters included in the voice data received through the microphone in the voice communication security maintaining mode, and the communication unit transmits the decoded characters to the counterpart terminal.

3. The device as claimed in claim 1, further comprising:

an encoder for encoding characters selected by a user through a corresponding encoding process to generate the encoded characters; and

a memory for storing the encoded characters in a character encoding mode,

wherein, when the encoded characters are included in voice data received through the microphone on the voice communication mode, the decoder decodes the encoded characters through a corresponding decoding process, and the communication unit transmits the voice data including the decoded characters to the counterpart terminal.

4. The device as claimed in claim 1, further comprising:

an encoder for encoding original characters selected by a user through the corresponding encoding process to generate the encoded characters; and

a memory for storing the original characters and the encoded characters in a character encoding mode,

wherein, the controller extracts the original characters corresponding to the encoded characters, and the communication unit transmits the voice data including the original characters to the counterpart terminal.

5. The device as claimed in claim 1, further comprising:

a memory for storing the encoded characters and original characters corresponding to the encoded characters;

an encoding unit for encoding the original characters to generate the encoded characters; and

a decoding unit for decoding the encoded characters included in voice data received in the voice communication mode.

6. A method of maintaining voice communication security in a terminal, the method comprising:

when voice data is received through a microphone in a voice communication mode, determining whether encoded characters are included in the voice data; and

decoding, upon a determination that the encoded characters are included in the voice data, the encoded characters included in the voice data and then transmitting the decoded characters to a counterpart terminal communicating with the terminal.

7. The method as claimed in claim 6, wherein determining whether encoded characters are included in the voice data comprises:

converting, when a specific user input in the voice communication mode is received, the voice communication mode into a voice communication security maintaining mode; and

determining whether encoded characters are included in voice data received from the microphone in the voice communication security maintaining mode.

8. The method as claimed in claim 6,

receiving characters selected by a user in a character encoding mode;

encoding the received characters through a corresponding encoding process to generate the encoded characters; and

storing the encoded characters.

9. The method as claimed in claim 6, further comprising:

receiving original characters selected by a user in a character encoding mode;

encoding the received original characters to generate the encoded characters; and

storing the original characters and the encoded characters.

10. The method as claimed in claim 6, wherein transmitting the decoded characters comprises:

decoding, when the encoded characters are included in the voice data, the encoded characters through a corresponding decoding process; and

transmitting the voice data including the decoded characters to the counterpart terminal.

11. The method as claimed in claim 6, wherein transmitting the decoded characters comprises:

extracting, when the encoded characters are included in the voice data, original characters corresponding to the encoded characters; and

transmitting voice data including the original characters to the counterpart terminal.

12. A computer-readable recording medium readable by a processor in which a program for executing a method of maintaining voice communication security in a terminal, the method comprising:

when voice data is received through a microphone in a voice communication mode, determining whether encoded characters are included in the voice data; and

decoding, upon a determination that the encoded characters are included in the voice data, the encoded characters included in the voice data and then transmitting the decoded characters to a counterpart terminal communicating with the terminal.

13. The computer-readable recording medium as claimed in claim 12, wherein determining whether encoded characters are included in the voice data comprises:

converting, when a specific user input in the voice communication mode is received, the voice communication mode into a voice communication security maintaining mode; and

determining whether encoded characters are included in voice data received from the microphone in the voice communication security maintaining mode.

14. The computer-readable recording medium as claimed in claim 12, wherein the method further comprises:

receiving characters selected by a user in a character encoding mode;

encoding the received characters through a corresponding encoding process to generate the encoded characters; and

storing the encoded characters.

15. The computer-readable recording medium as claimed in claim 12, wherein the method further comprises:

receiving original characters selected by a user in a character encoding mode;

encoding the received original characters to generate the encoded characters; and

storing the original characters and the encoded characters.

16. The computer-readable recording medium as claimed in claim 12, wherein transmitting the decoded characters comprises:

decoding, when the encoded characters are included in the voice data, the encoded characters through a corresponding decoding process; and

transmitting the voice data including the decoded characters to the counterpart terminal.

17. The computer-readable recording medium as claimed in claim 12, wherein transmitting the decoded characters comprises:

extracting, when the encoded characters are included in the voice data, original characters corresponding to the encoded characters; and

transmitting voice data including the original characters to the counterpart terminal.
