Embodiment Construction
[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0058] The embodiment of the present invention discloses a multi-party data security computing method, see figure 1 As shown, the method includes:
[0059] S11: Receive the required calculation polynomial sent by the demand terminal.
[0060] Specifically, the demand terminal provides the polynomial that it needs to calculate using the original data. The original data required to calculate the polynomial are distributed on different data source terminals. The...

The application discloses a method, system, device and computer-readable storage medium for multi-party data security calculation, which decomposes the original data and distributes them to different computing servers, and splits them according to the corresponding monomial formula in each different computing server. Divide the data into calculations, add server random numbers to the calculation results, and then resolve the intermediate results by the resolution server to obtain a simplified third intermediate result, which is finally sent to the demand terminal for final resolution to obtain the final calculation result , which realizes that any party participating in the calculation does not need to provide the original data to other parties participating in the calculation, solves the trust problem between the participating parties, and can complete the secure calculation of multi-party data without the original data leaving the local area. Based on the security of the transmission link and the computing environment, the data participating in the calculation is guaranteed to be safe and not leaked, and the original plaintext data during the calculation process is invisible to protect user privacy.
Description
technical field [0001] The present invention relates to the field of information security, in particular to a multi-party data security computing method, system, device and computer-readable storage medium. Background technique [0002] When the data of multiple data sources (assume A and B) are fused together for calculation, one method is that A sends the data to B and completes the calculation on the B side, or B gives the data to A and completes the calculation on the A side. In this mode, whether A sends data to B or B sends data to A, there is a risk of data flowing out of the local security domain. At the same time, A or B can see the original data transmitted by the other party, and can copy and sell the other party's data again, which is not safe and may leak the user's privacy. [0003] Another way is to find a third-party C. A and B transmit the data to C, and the data calculation is completed on the C side. Under this method, C can obtain the original data upl...
