Abstract
A data privacy protection method based on multi-layer encryption is disclosed, which is related to the technical field of network technologies. The method includes: by an initial client, encrypting service data based on a public key set to obtain first to-be-processed data, and sending the first to-be-processed data to a next client; by an intermediate client, obtaining the first to-be-processed data sent by a previous client, encrypting service data based on a public key set to obtain second encrypted data, and sending second to-be-processed data and the second encrypted data to a next client; by a final client, obtaining the second to-be-processed data and the second encrypted data sent by a previous client, decrypting the second to-be-processed data and the second encrypted data based on its own private key, to obtain service data of each of other clients other than the final client itself, and sending the service data of all of the clients in a data privacy protection system to a preset service platform. The embodiments of the present application are applied to reduce the risk of user's privacy data leakage.
