Data anonymization processing system, data anonymization processing device, and data anonymization processing method

Abstract

To provide a data anonymization processing system that, in data on which a user executes anonymization processing, easily and freely designates a desired anonymization technique in a desired anonymization part.SOLUTION: A data anonymization processing system comprises an application server device and a database management system. The application server device has a request message processing unit, a data acquisition unit, and an anonymization processing unit. The request message processing unit receives input information including table designation information, a data range to be acquired, a column to be anonymized, and an anonymization technique, which are input by a user. The data acquisition unit specifies a designated table from a data group managed by the database management system, and acquires data in a designated range as anonymization source data. The anonymization processing unit executes anonymization processing on information included in the column to be anonymized in the anonymization source data by using a designated anonymization technique to generate anonymization data, and provides it to the user.SELECTED DRAWING: Figure 5

Claims
