Efficient Privacy-Preserving Identity Scheme for Electronic Validation of Phase 1 Clinical Trials

摘要

New drug studies are essential to advance the pharmaceutical industry's ability to fight diseases. These studies are typically performed in four phases. We are interested in "phase 1" clinical trials where the goal is to evaluate the safety of a new drug. Contract research organizations recruit participants for their studies and need to verify electronically certain criteria without revealing the identity of these participants to other organizations. We outline some potential attacks against current identity representation schemes. Afterwards, we present privacy-preserving techniques to represent the identity of a participant in a scheme where operations can be performed efficiently and accurately. Our methods and scheme can also be applied to other domains to preserve an individual's privacy.
