Abstract

A method for performing video communication is provided. The method includes: creating and saving a bio key using a user'"'"'s biological information before first and second terminals perform the video communication; establishing a session, wherein the first terminal requests voice communication with the second terminal; exchanging bio keys saved in the respective terminals and saving the same; starting a Secure Real-Time Transport Protocol (SRTP) session, wherein the first and second terminals create a session sharing key using the exchanged bio keys; creating a restored bio key by obtaining the biological information from data received by first and second terminals and performing a user certification by comparing the bio key with the restored bio key.

Claims

1. A method for performing communication the method comprising:

creating a first bio key using a first user'"'"'s biological information and saving the first bio key in a first terminal;

creating a second bio key using a second user'"'"'s biological information and saving the second bio key in a second terminal;

establishing a session, wherein the first terminal transmits a request for communication to the second terminal;

transmitting the first bio key from the first terminal to the second terminal and transmitting the second bio key from the second terminal to the first terminal;

creating a session sharing key using the first bio key and the second bio key;

creating a restored bio key using at least one of the first user'"'"'s biological information and the second user'"'"'s biological information; and

performing user certification by comparing the first bio key with the restored bio key.

2. The method as recited in claim 1, wherein the creating the first bio key comprises:

encoding and decoding the biological information; and

creating a digital bio key by extracting featuring information of the biological information.

3. The method as recited in claim 1, wherein the creating the first bio key comprises creating a plurality of bio keys respectively corresponding to a plurality of encoding and decoding methods.

4. The method as recited in claim 3, further comprising selecting at least one encoding method and at least one decoding method from the plurality of encoding and decoding methods.

5. The method as recited in claim 1, wherein the session sharing key is created based on a Diffie-Hellman algorithm.

6. The method as recited in claim 1, wherein at least one of the first user'"'"'s biological information and the second user'"'"'s biological information includes face featuring information extracted from a featuring point of the first user'"'"'s face or the second user'"'"'s face.

7. An apparatus for performing communication, comprising:

an outer input device that receives voice and video signals;

an outer output device that outputs the voice and video signals;

an encoding and decoding module that encodes and decodes the voice and video signals transferred from the outer input device and outputs a decoded video signal;

a biological information extracting part that obtains biological information from the video signal outputted from the encoding and decoding module and outputs the biological information;

a bio key creating part that creates and manages a first bio key using the biological information outputted from the biological information extracting part;

a session sharing key creating part creates a session sharing key using the first bio key and a second bio key;

a telecommunication module that transmits and receives packet data encoded using the session sharing key; and

an encryption certifying part that creates a restored bio key and certifies the packet data encoded using the session sharing key.

8. The apparatus as recited in claim 7, wherein the biological information extracting part extracts featuring information from the biological information;

and

the bio key creating part creates a digital bio key based on the extracted featuring information.

9. The apparatus as recited in claim 8, wherein the encoding and decoding module includes a plurality of encoders and a plurality of decoders which respectively encode and decode the voice and video signals transferred from the outer input device according to a plurality of encoding and decoding methods, and

wherein the bio key creating part creates a plurality of bio keys respectively corresponding to the plurality of encoding and decoding methods.

10. The apparatus as recited in claim 7, wherein the biological information extracting part includes:

a facial area recognizing part that scans a facial area included in the decoded video signal output from the encoding and decoding module; and

a featuring point extracting part that recognizes a featuring point of the facial area using geometrical information of the scanned facial area, and extracts face featuring information with respect to the recognized featuring point of the facial area.

11. The apparatus as recited in claim 7, wherein the encryption certifying part controls the biological information extracting part to extract the biological information, and certifies the packet data encoded using the session sharing key by confirming whether the first bio key is the same as the restored bio key.

12. A method for performing communication, the method comprising:

creating a first bio key using a user'"'"'s biological information and saving the first bio key in a first terminal;

transmitting, by the first terminal, a request for communication to a second terminal;

receiving a second bio key from the second terminal and storing the second bio key;

creating a session sharing key using the first bio key and the second bio key;

encoding data using the session sharing key; and

transmitting the encoded data to the second terminal.

13. A method for performing communication, the method comprising:

creating a second bio key using a user'"'"'s biological information and saving the first bio key in a second terminal;

receiving a request for communication;

receiving a first bio key from a first terminal and storing the first bio key;

transmitting the second bio key to the first terminal;

creating a session key using the first bio key and the second bio key;
