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 between a first terminal and a second terminal, the method comprising:

generating, by the first terminal, a first biographical (bio) key using bio information of a user;

sending, by he first terminal, an INVITE request message for a video communication to the second terminal;

receiving, by a first terminal, an INVITE response message in response to the INVITE request message from the second terminal for establishing a session between the first terminal and the second terminal;

modifying, by the first terminal, the first bio key into a first modified bio key;

sending, by the first terminal, the first modified bio key to the second terminal;

receiving, by the first terminal, a second modified bio key from the second terminal;

generating, by the first terminal, a session shared key using the first modified bio key and the second modified bio key;

encrypting, by the first terminal, packet data using the session shared key; and

sending, by the first terminal, the encrypted packet data to the second terminal.

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

extracting featuring information from the bio information; and

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

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

4. The method as recited in claim 3, further comprising selecting any one encoding and decoding method to be applied to communication, from among the plurality of encoding and decoding methods.

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

6. The method as recited in claim 1, wherein the bio information comprises face featuring information extracted from a featuring point of the user'"'"'s face.

7. A first terminal for performing communication between the first terminal and a second terminal, comprising:

a bio key creating part for generating a first biographical (bio) key using bio information of a user;

a transmitter for sending an INVITE request message for a video communication to the second terminal, sending a first modified bio key to the second terminal, and sending encrypted packet data to the second terminal;

a receiver for receiving an INVITE response message in response to the INVITE request message from the second terminal for establishing a session between the first terminal and the second terminal, and receiving a second modified bio key from the second terminal; and

a controller for modifying the first bio key into the first modified bio key, generating a session shared key using the first modified bio key and the second modified bio key, and encrypting packet data using the session shared key.

8. The first terminal as recited in claim 7, wherein the bio key creating part extracts featuring information from the bio information, and creates a digital bio key based on the extracted featuring information.

9. The first terminal as recited in claim 8,

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

10. The first terminal as recited in claim 9, wherein the controller is configured to select any one encoding and decoding method to be applied to communication, from among the plurality of encoding and decoding methods.

11. The first terminal as recited in claim 7, wherein the bio information comprises face featuring information extracted from a featuring point of the user'"'"'s face.
