Electronic commerce data processing method and system

The invention discloses an e-commerce data processing method and system, a data acquisition unit, a data preprocessing unit, a data encryption unit and a data output unit, relates to the technical field of e-commerce processing, and solves the problems that a traditional encryption mode is relatively single, the characteristics of data are not reasonably utilized for processing, and the processing efficiency is low. In order to solve the technical problem of data leakage during encryption in the prior art, the electronic commerce data is cleaned and preprocessed, repeated data and incomplete data in the electronic commerce data are cleaned, the data quality and the accuracy of statistical analysis are improved, then the electronic commerce data are classified, and the accuracy of statistical analysis is improved. According to the method, data are classified, repeated data analysis is carried out on the classified data, the whole is encrypted according to the characteristics of the repeated data, encryption is
