Embodiment 1

[0024] A secure data fusion system suitable for multiple application scenarios, please refer to the attached figure 1, this embodiment includes a data receiving node 20, several data storage nodes 30, several reserved nodes 40, a model node 50 and an information node 60, and the data receiving node 20 receives the data description text and the external primary key field identification submitted by the data source party 10 Information, assigning row numbers to the data rows of the data source 10, the reserved node 40 is set at the data source 10, the reserved node 40 and the data source 10 system synchronize data, and the reserved node 40 makes several copies for the data row, and the copy is associated with the row Numbering, reserved node 40 retains a copy as a reserved copy, splits the real value of the numerical field of the data row into several addends, and several addends are assigned to several copies respectively, and the real value of the non-numeric field is reserved ...

Embodiment 2

[0053] A secure data fusion system applicable to multiple application scenarios, this embodiment provides a further improvement on the execution of the data processing model on the basis of the first embodiment. Please refer to the attached Figure 4 , in this embodiment, the execution of the data processing model includes the following steps:

[0054] The row number assigned to the data row by the data source 10 includes the hot and cold attribute identification of the data. If the row number is cold data, execute:

[0055] Step B01) Reserve the node 40 to calculate the real value of the data row field and the value from the 2nd power to the Nth power, and create a new 2nd to Nth power column for each numeric field in the copy;

[0056] Step B02) split the 1st power to the Nth power value of the real value of the field into several addends, and assign them to the reserved copy and the rest of the copy storage; before the data storage node 30 builds a secure multi-party Perf...

Abstract

The invention relates to the technical field of big data, in particular to a security data fusion system suitable for multiple application scenarios. The security data fusion system comprises a data receiving node, a data storage node, a retention node, a model node and an information node. The data receiving node receives a data description text of a data source party and external primary key field identification information, a real value of a numeric field of a data line is split into a plurality of additions and copies to be distributed to a data storage node for storage, a model node receives a data processing model submitted by a data demander, and an information node displays a line number of the data line received by a data receiving node, a corresponding data description text and external primary key field identification information. The data demander submits the line number and the model number to the model node, and the data storage node and the retention node establish multi-party security calculation to substitute the data line into the data processing model, and send a model result to the data demander. The system has the substantive effects that the security of the data is improved, and the privacy of the data is kept.

Description

technical field [0001] The invention relates to the field of big data technology, in particular to a secure data fusion system applicable to multiple application scenarios. Background technique [0002] Hot data refers to the data that exists in the data demand side system, the business has not been completed or there may be updates, and the data needs to be accessed and updated. The cold data refers to the completed business archive data, which does not need to be updated. Cold data is usually suitable for offline analysis, such as model training in machine learning or big data analysis. However, after the machine learning training is completed, the latest business data needs to be substituted in order to know the business development. With the development of information technology, new technologies represented by intelligent manufacturing and artificial intelligence are starting a new revolution and leading the global economic development. The core of artificial intelli...
