This module is the implementation of Vizard Server that encrypts data submitted by data owners and stores it into back-end database. It also stores DPF keys submitted by data owners, and processes the queries issued by data consumers.
The server module does not contain standalone RESTful APIs. It interacts with other modules through Kafka clusters. Schemes used in back-end databases are provided in vizard-db.sql.
Configuration properties of this module are listed as following:
