More Information
Summary:The invention provides a data sorting method and a data processing method based on privacy protection. Based on the method, the computing node can jointly use the ciphertext data of the first data group and the ciphertext data of the second data group through the translation operation according to the preset protocol rule on the premise of protecting the data privacy of the first data party and the second data party, so as to perform joint sorting; the target sequence group containing the ciphertext data of the first data and the ciphertext data of the second data, which are arranged according to the preset sorting rule, is efficiently obtained. Carrying out data binning by utilizing the target sequence group to obtain a plurality of data binning; according to the data processing method, the first data and the second data are combined, and the information value about the first data and the second data after combination is calculated according to each data sub-box, so that the data quality of the first data an
