ICPSR Confidentiality Procedures

  • Confidentiality review of all deposited datasets at ICPSR. This Web page details procedures ICPSR employs in assessing datasets in terms of confidentiality concerns.

  • Direct and indirect identifiers in ICPSR data. This Web page illustrates the different types of identifiers that may be found in data files and describes techniques for handling them.

  • Disclosure analyses undertaken by the Substance Abuse and Mental Health Data Archive (SAMHDA) at ICPSR. The SAMHDA archive is employing some innovative practices to safeguard confidentiality in data they distribute. This page describes some of these new procedures.

  • Restricted data from ICPSR. In some cases, modifying a dataset to remove identifiers can compromise the research value of the data. In special circumstances, users can get access to restricted-use datasets after signing a contract and agreeing to certain conditions. Our Web site describes the procedures involved in obtaining and using restricted data. Details about the NACJD approach to providing restricted-use data are available.
