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.
Claims9
A method for analyzing confidential data, applied to segment authorizations of a cloud host according to corresponded first and second keys, including the steps of:
- Inputting the first key into the cloud host and obtaining a first analysis authorization;
- Connecting an end-user device to the cloud host, and reading a plurality of first data and an operating model into an encrypted cloud space in the cloud host according to the first analysis authorization;
- Performing a first analysis with the plurality of first data stored in the encrypted cloud space and obtaining a first analysis result according to the operating model by using the cloud host;
- Uploading the first analysis result to the cloud host and performing verification;
- When the first analysis result passes the verification, inputting the second key into the cloud host and obtaining a second analysis authorization;
- Transferring a plurality of second data into the encrypted cloud space by the end-user device according to the second analysis authorization;
- and
- Performing a second analysis with the plurality of second data stored in the encrypted cloud space and obtaining a second analysis result according to the operating model by the cloud host;
- wherein the plurality of first data is generated by simulating according to a format of the plurality of second data or by random sampling the plurality of second data.
A system for analyzing confidential data, comprising:
- At least one encrypted storing unit that stores a plurality of first data and second data;
- A cloud host that connects to at least one encrypted cloud space;
- and
- An end-user device that connects to the cloud host, transmitting a first key and a second key to the cloud host;
- the cloud host follows the first key to send a first analysis authorization to the end-user device;
- the cloud host follows the second key to send a second analysis authorization to the end-user device;
- the end-user device follows the first analysis authorization to send a plurality of first data and one operating model to the encrypted cloud space;
- the cloud host follows the operating model to perform a first analysis on the plurality of first data and obtains a first analysis result;
- the end-user device follows the second analysis authorization to send a plurality of second data to the encrypted cloud space;
- the cloud host follows the operating model to perform a second analysis on the plurality of second data and obtains a second analysis result, while performing the first analysis, the cloud host connects to a network;
- and while performing the second analysis, the cloud host disconnects the network;
- the plurality of second data are closed encrypted data;
- wherein the plurality of first data is generated by simulating according to a format of the plurality of second data or by random sampling the plurality of second data.
