BIG DATA PERSONAL INFORMATION ANONYMIZATION AND ANONYMOUS DATA COMBINATION METHOD

摘要

The present invention relates to a big data personal information anonymization and combination method for enabling distributed data to be combined while anonymizing big data such that the big data can be freely distributed to an external system without concern for the leakage of personal information. According to the present invention, the combination accuracy of an anonymous data set can be improved while guaranteeing the impossibility of re-identification of anonymous data by grouping synchronization dictionary values in a synchronization dictionary domain, applying an error to each group so as to define a cell, and assigning a synchronization attribute on the basis of the section of the cell.
