<p>The embodiments of the present invention disclose an information processing method, a trust server and a cloud server. The method comprises: acquiring user data of a user terminal; extracting abstract information about the user data, wherein the abstract information contains privacy information and non-privacy information about a user; generating a unique identifier (UID) for the privacy information; and transmitting the non-privacy information and the UID to a cloud server, so as to enable the cloud server to save the correlation between the non-privacy information and the UID. Since the trust server is introduced in the embodiments of the present invention, after the abstract information about the user is processed by means of the trust server, the cloud server does not save the complete abstract information consisting of the privacy information and the non-privacy information any longer, but only saves the non-privacy information in the abstract information and the UID of the privacy information, so that the third party cannot acquire the privacy information about the user from the cloud server, thereby improving the safety performance of a cloud computing system.</p> |
