Privacy-Preserving Anonymity for Periodical Releases of Spontaneous Adverse Drug Event Reporting Data: Algorithm Development and Validation

What is it about?

We present the privacy threat casused by the existence of follow-up cases in periodical publishing of spontaneous reporting system (SRS) data of adverse drug events. An novel privacy preserving data anonymization method is proposed to prevent the privacy attack through cross linkage of follow-up cases.
