This paper introduces SURROGATOR, an open-source framework that replaces personal identifiable information with fictitious, high-fidelity synthetic surrogates to maintain text utility for human and artificial intelligence. We focus on the automated replacement of names, dates, and locations. Evaluation on a synthetic clinical corpus demonstrated high data utility, with named entity recognition performance remaining en par with the original text (F1-score of 0.70 vs. 0.73). Furthermore, a re-identification attack using a large language model resulted in an accuracy of 50.8%, which is equivalent to random chance. We conclude that SURROGATOR effectively balances patient privacy and data utility, providing a robust solution for the secure sharing of clinical documents in medical research.<\/jats:p>","DOI":"10.3233\/shti260440","type":"book-chapter","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T22:04:58Z","timestamp":1779401098000},"source":"Crossref","is-referenced-by-count":0,"title":["The SURROGATOR Framework for Context-Aware Surrogation of Privacy Sensitive Information in Medical Text"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9889-162X","authenticated-orcid":false,"given":"Christina","family":"Lohr","sequence":"first","affiliation":[{"name":"Institute for Medical Informatics, Statistics and Epidemiology (IMISE), University Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marvin","family":"Seiferling","sequence":"additional","affiliation":[{"name":"Klaus Tschira Institute for Integrative Computational Cardiology, University Hospital Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Wiesenbach","sequence":"additional","affiliation":[{"name":"Klaus Tschira Institute for Integrative Computational Cardiology, University Hospital Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8875-5426","authenticated-orcid":false,"given":"Jakob","family":"Faller","sequence":"additional","affiliation":[{"name":"Medical Center for Information and Communication Technology, University Hospital Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9468-6311","authenticated-orcid":false,"given":"Christoph","family":"Dieterich","sequence":"additional","affiliation":[{"name":"Klaus Tschira Institute for Integrative Computational Cardiology, University Hospital Heidelberg, Germany"},{"name":"Partner Site Heidelberg\/Mannheim, German Centre for Cardiovascular Research (DZHK), Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Opening the Personal Gate between Technology and Health Care"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI260440","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T22:04:58Z","timestamp":1779401098000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI260440"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,21]]},"ISBN":["9781643686615"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti260440","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,21]]}}}
