BLOCKCHAIN-BASED DATA STATISTICAL METHOD AND DEVICE

摘要

Disclosed in the present invention are a blockchain-based data statistical method and device. The method comprises: a data server signs data to be subjected to statistics collection by using a second private key to generate signature information, encrypts the signature information and the data by using a first public key to generate encrypted data, and sends the encrypted data to a forwarding server, the forwarding server sends the encrypted data to a statistical server, and the statistics server decrypts the encrypted data by using a first private key corresponding to the first public key to obtain the data to be subjected to statistics collection and the signature information, and after the signature information passes verification by using a second public key corresponding to the second private key, collects statistics about the data to obtain a statistical result. The technical solution is used for providing a simple and easy-to-use data statistical method, and protecting the privacy of each participant.
