Problems solved by technology
One way to overcome data availability is to share data between different contributing sources, for example, for the education industry, sharing data from different schools or training centers, but doing so may cause problems for students, parents or schools themselves. Privacy concerns and, in some countries, may also be legal issues

Embodiment 4
[0075] Embodiment 4, in combination with the above embodiments, whenever there is additional or updated original data in any of the contribution sources, all contribution sources will execute the solutions of the above embodiments again to start a new iteration.
[0076] Specifically, the contribution source will execute the following solution again: periodically and / or aperiodically share the reconstruction data obtained in the above-mentioned embodiments with other contribution sources.
[0077] The contribution sources will execute the following scheme again: After the contribution sources share data periodically and / or aperiodically as in the above-mentioned embodiments, each contribution source will clear its historical data reconstructed from other contribution sources.
[0078] The contributing sources will again execute the following scheme: when each contributing source receives new shared data, the contributing sources will find the best reconstructed data associated ...

The embodiment of the invention provides a method, device and system for collecting and sharing education data and a storage medium, and the privacy of students cannot be leaked. According to the method, the data with the original distribution reserved is obtained by transforming and reconstructing the education data, the data can still be used for corresponding data processing, the situation of privacy disclosure caused by direct sharing of the original data can be avoided by sharing the data with the original distribution reserved, and the data security is improved; each contribution sourceshares own data with other contribution sources; wherein the shared data is a copy of the transformed and reconstructed data; each contribution source converts and reconstructs the extended data set again; obtaining optimal reconstruction data, each contribution source shares the reconstruction data with other contribution sources; therefore, all the contribution sources work cooperatively, the optimal reconstruction data under the current condition can be obtained by each contribution source according to the reconstruction data and the original data, and the optimal reconstruction data not only can improve the data security, but also can ensure that the result obtained by data processing through the optimal reconstruction data is most similar to the original data.
Description
technical field [0001] The present invention relates to the technical field of privacy-protected data sharing, in particular to a method, device, system and storage medium for sharing educational data. Background technique [0002] It is well known that summary statistical descriptions can be very missing and even very misleading. The same mean and standard deviation, for example, can be associated with very different distributions. [0003] When using modern AI / ML technologies to reshape education and other industries, deep data mining can often reveal hidden patterns and provide new thinking to solve problems, and its superiority often greatly exceeds traditional methods. [0004] However, in order to really effectively use artificial intelligence and machine learning to play an important role in these aspects, the premise is that there must be a large enough amount of data. One way to overcome data availability is to share data between different contributing sources, fo...
