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.
