The present invention relates to an online stock transaction method using two channels and, more specifically, comprises the steps of: a first user terminal inputting a unique ID information and a password of a user into a stock firm server to perform a login; the stock firm server comparing the ID information and the password received from the first user terminal with a prestored ID information and passwords to perform a first user authentication for a user; the stock firm server generating a user authentication number according to the performance of the first user authentication; the stock firm server transmitting the user authentication number to a second user terminal via a short message service; the second user terminal transmitting the user authentication number, received from the stock firm server, to the first user terminal; the first user terminal transmitting the user authentication number, received from the second user terminal, to the stock firm server; and the stock firm server comparing the user authentication number, received from the first user terminal, with its generated user authentication number to perform a second user authentication. By such a configuration, the online stock transaction method using the two channels according to the present invention performs the user authentication two times by using simultaneously the first user terminal like a PC and the second user terminal like a mobile phone, thereby enabling only an access allowed user to access the stock firm server, so that it may enhance user security. |
