Common techniques for ensuring privacy focus more on security and validation and are vulnerable to privacy attacks. Yet, it is only through the secondary use of healthcare data that we can ultimately achieve Elias Zerhouni’s vision to “Transform Medicine from Curative to Preemptive”. After all, it is the analysis and sharing of data that is crucial to understanding patterns within the healthcare population. But we cannot do this unless we can ensure the privacy of the individual patient. In this paper, we review some of the common methods used to ensure privacy, including the use of privacy algorithms, and emphasize the use of differential privacy algorithms and the application of differential privacy via Privacy Integrated Queries (PINQ). 000000391 540__ $$fCC BY 000000391 542__ $$fIn copyright - single owner 000000391 650__ $$aConfidentiality$$017009 000000391 650__ $$aPrivacy$$031186 000000391 650__ $$aStatistics as Topic$$026381 000000391 691__ $$aSchool of Medicine$$041369 000000391 692__ $$aDepartment of Medical Informatics and Clinical Epidemiology$$041422 000000391 7001_ $$aLee, Denny$$uOregon Health and Science University$$041354 000000391 7201_ $$aLogan, Judith$$uOregon Health and Science University$$041354$$7Personal$$eAdvisor 000000391 8564_ $$9b72d20b2-da88-4206-839d-e3320bb8035a$$s1889115$$uhttps://digitalcollections.ohsu.edu/record/391/files/392_etd.pdf 000000391 905__ $$a/rest/prod/2f/75/r8/05/2f75r8056 000000391 909CO $$ooai:digitalcollections.ohsu.edu:391$$pstudent-work 000000391 980__ $$aBiomedical Informatics
