Privacy-preserving data acquisition protocol

Current investigative data acquisition techniques often breach human and natural rights of the data subject and can jeopardize an investigation. Often the investigators need to reveal to the data controller precise details of their suspect´s identity or suspect´s profile. In this research a novel approach to investigative data acquisition is presented and privacy preserving Investigative Data Acquisition Protocol (IDAP) is defined. This protocol is the first that allows for performing private information retrieval of records matching multiple selection criteria.
