Abstract
Civil aviation airports generate a large amount of data every day and it is necessary to deposit, analyze and process the civil aviation data by third parties and feedback the information to civil aviation companies to improve their services.However, sensitive data may leak, so data desensitization is required.We first introduced several general data desensitization techniques, then analyzed the data in the civil airport flight information system (CAFIS) database, and used the sensitive data of the CAFIS as the research object, and defined the sensitive data fields in the data of CAFIS.A combined desensitization method for CAFIS privacy data is proposed.For non-statistical identifier sensitive data, we used data obfuscation, encryption and anonymity method etc.to desensitize the data.For statistical identification data we used differential privacy technic to desensitize the data.Finally, the desensitization results were analyzed and the results show that the desensitization method used in this paper could be applied to data desensitization of CAFIS.
