My data are on very sensitive topics; the risk to participants is very high should they be re-identified. How can I protect the respondents?

ICPSR evaluates all data files for disclosure risk using state-of-the-art techniques developed under a grant from the National Institutes of Health. From this evaluation, staff recommend a method of data release that protects the respondents from re-identification while retaining the analytic utility of the data. Release options include public release; public release with disclosure control practices put in place; restricted release with a user contract; enclave only release; and online analysis only with no micro-data download. A full public release is only warranted when there is little risk of re-identification or the data have been sufficiently transformed to substantially reduce that risk.
