<p>An embodiment of the present invention relates to a data sharing method and a data sharing system using the same, wherein the data sharing method enables a first terminal of an information requester and a second terminal of an information provider to share encrypted data. According to the embodiment of the present invention, the data sharing method comprises: a first step in which the second terminal receives first encryption information along with a request for sharing desired data from the first terminal; a second step in which the second terminal restores an encryption key of the first terminal included in the received first encryption information; a third step in which the second terminal encrypts the restored encryption key and the data requested for sharing by the first terminal, and transmits the encrypted data to the first terminal; a fourth step in which the first terminal compares an encryption key of the first terminal with the encryption key included in the encrypted data received from the second terminal; and a fifth step in which the first terminal decrypts the encrypted data in case the encryption keys are identical.</p> |
