Data mining device for privacy protection

Abstract

The invention provides a data mining device for privacy protection. The device comprises an original database, a memory, an input device, a processor, a protection server and a common server, whereinthe original database is used for storing original data records of a user; the memory is used for storing sensitive data; the input device is connected with the memory and used for inputting the sensitive data into the memory; the processor is connected with the memory and the original database and used for mining data, matched with the sensitive data in the memory, in the original database and performing privacy marking on the matching data; the protection server is connected with the processor and used for receiving the data subjected to privacy marking in the original database to protect that data and reject external access; and the common server is connected with the processor, receives data not subjected to privacy marking in the original database and permits external access to the data. Through the privacy protection device, protection at different levels can be performed on all kinds of privacy data according to form changes by constantly adjusting the level of the sensitive data.

Description

technical field [0001] The invention relates to a data mining device, in particular to a data mining device for privacy protection. Background technique [0002] Privacy-preserving data mining techniques have become an important topic this year due to the vast amount of consumer data generated by automated systems on the Internet. The proliferation of electronic commerce on the World Wide Web has resulted in the storage of vast amounts of transactional and personal information about users. In addition, the development of hardware technology also leads to the feasibility of traceability of personal transaction information in daily life. [0003] For example, a simple transaction using a credit card can result in the system automatically storing information about the user's purchasing behavior. In many cases, users are unwilling to provide such personal data unless their privacy rights are protected. Therefore, in order to ensure effective data collection, it is important t...
