Abstract: The present application is related to system and method for analyzing confidential data. Firstly, a first key is used to obtain a first analysis authorization for proceeding a first analysis responsive to an operational model in an encrypted cloud space with a connection of a network. Then, the result of the first analysis is verified. While the verifying of the operational model is pass, a second key is used to obtain a second analysis authorization for proceeding a second analysis responsive to an operational model without the connection of the network. Thereby, the cloud technique for analyzing data can be applied for analyzing confidential data.
