In the data sharing mode, a network firewall is often arranged between an internal network and an external network to ensure the information security of enterprises. Meanwhile, in order to ensure the privacy of the electric power metering information, before the applicant obtains the original data, the data center performs shielding processing on the data according to the data sharing requirement. In addition, a data sharing mode is provided, wherein the power data are deployed in a preset container, an IP number and a port number are allocated to the preset container, a user directly accesses the preset container through the IP number and the port number, and the original power data are processed according to a corresponding sharing request, so that the user can only obtain the processed data.
