METHOD FOR SIMULTANEOUSLY PROCESSING ENCRYPTION AND DE-IDENTIFICATION OF PRIVACY INFORMATION, SERVER AND CLOUD COMPUTING SERVICE SERVER FOR THE SAME

摘要

A method, a server device, and a cloud computing service server device for simultaneously processing the encryption and de-identification of personal information are provided. The method includes the steps of collecting plaintext data including personal information about a predetermined personal information storage transaction of a first personal information processing application of a web application server, and storing plaintext data including the personal information according to a predetermined encryption algorithm. Generating encrypted text data by encryption, generating non-identifying data by de-identifying plain text data including the personal information, storing the encrypted text data in a cryptographic storage, and storing the encrypted text data in at least a part of the non-identifying data. And generating a non-identifying data combining cryptographic identification key by combining a cryptographic identification key corresponding to the cryptographic data, and returning the non-identifying data combining cryptographic identification key.
