Survey of Research on Anonymization Privacy-preserving Techniques

With the rapid development of Internet technology,privacy preservation has been an essential issue for individuals or organizations.The emergence of kinds of data mining tools makes privacy disclosure issues be increasingly critical.The method of releasing data through removing identifier from the table could not truly prevent privacy disclosure.The attacker can also infer the private data of the corresponding individual with high probability by linking operation.Anonymization is one of the primary techniques realizing privacy protection in data dissemination environment.The paper simply introduces the general concept and basal principle of the anonymization techniques,and mainly analyzes and summarizes the progress of the anonymization principles,anonymization methods and anonymization metrics.Finally,the present problems and directions for future research are discussed.
