Ready-to-Use Open Source Privacy Computing Platform. Typically when we query data, the data provider will certainly know our query conditions, otherwise, the results cannot be returned. However, in some cases, the querying party does not want others to know the query conditions, yet still wants to obtain results. This may sound like an impossible task to complete. But don't worry, there's a specialized technical field called privacy computing. If you don't understand it, this open source privacy computing platform, PrimiHub, allows you to experience the charm of privacy computing without a background in privacy computing technology, enabling easy achievement of 'data is usable but not visible'!
