摘要

A method for protecting user privacy for a privacy protection application, includes: receiving a request for user data of a user from a third-party service; receiving, from the user, an authorization for the request for the user data; acquiring the user data from a plurality of different storage facilities; processing the acquired user data with a data model provided by the third party service, wherein the data model comprises a multi-party computation model configured to generate processed user data based on the user data stored at the plurality of different storage facilities; encrypting the processed user data using a third-party public key associated with the third-party service; and transmitting the encrypted processed user data to the third-party service to enable the third-party service to decrypt the encrypted processed user data to obtain the processed user data.
