Embodiments of the present invention disclose an information processing method, a trusted server, and a cloud server. The method includes: acquiring user data of a user terminal; extracting summary information of the user data, where the summary information includes privacy information and non-privacy information of 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 that the cloud server saves a correspondence between the non-privacy information and the UID. Because a trusted server is introduced in the embodiments of the present invention, after the summary information of the user is processed by the trusted server, the cloud server no longer saves complete summary information formed by the privacy information and the non-privacy information, but saves only the non-privacy information in the summary information and the UID of the privacy information in the summary information, so that a third party cannot acquire the privacy information of the user from the cloud server, thereby improving security performance of a cloud computing system. |
