Problems solved by technology

[0005] The current data binning method is usually used to bin plaintext data. For ciphertext data, it is impossible to calculate the splitting point required for binning according to the specific value of the data, resulting in the need to expose the plaintext data during the data binning process. It is difficult to ensure the privacy and security of data

Abstract

Embodiments of the present application provide a data processing method, device, and device for data processing. The method is used to determine the segmentation point of the data to be binned based on the ciphertext of the data, wherein the method includes: constructing a data array according to the ciphertext of the data to be binned; determining the number of bins of the data to be binned and binning mode; determine the quantile according to the binning number and the binning mode; determine the corresponding value of the data to be binned in the binning mode based on the quantile and the data array cut point. In the embodiment of the present application, the segmentation point of data binning can be determined on the basis of the ciphertext, and then the binning of the ciphertext data can be realized, and the privacy and security of the data can be ensured.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device and device for data processing. Background technique [0002] With the advent of the era of big data, big data analysis also came into being. In scenarios such as big data analysis, it is often necessary to perform operations such as statistics, comparison, and analysis on certain types of data. When the data is collected, there may be numerical noise such as random errors, outliers, and extreme values, which will affect the speed of the algorithm if it is used directly. In addition, some algorithms do not support continuous variables, so the data needs to be preprocessed. [0003] Data binning is a commonly used data preprocessing method. "Binning" is actually a sub-interval divided according to the attribute value of a certain attribute corresponding to the data, such as a sub-interval divided by age, a sub-interval divided by h...
