Unfortunately, existing explanations of differential privacy fail to set accurate privacy expectations for data subjects, which depend on the choice of deployment model. We design and evaluate new explanations of differential privacy for the local and central models, drawing inspiration from prior work explaining other privacy-enhancing technologies such as encryption. We reflect on the challenges in evaluating explanations and on the tradeoffs between qualitative and quantitative evaluation strategies. These reflections offer guidance for other researchers seeking to design and evaluate explanations of privacy-enhancing technologies.<\/jats:p>","DOI":"10.56553\/popets-2025-0150","type":"journal-article","created":{"date-parts":[[2025,7,13]],"date-time":"2025-07-13T15:58:27Z","timestamp":1752422307000},"page":"653-678","source":"Crossref","is-referenced-by-count":2,"title":["Models Matter: Setting Accurate Privacy Expectations for Local and Central Differential Privacy"],"prefix":"10.56553","volume":"2025","author":[{"given":"Mary Anne","family":"Smart","sequence":"first","affiliation":[{"name":"Purdue University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Nanayakkara","sequence":"additional","affiliation":[{"name":"Harvard University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Cummings","sequence":"additional","affiliation":[{"name":"Columbia University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Kaptchuk","sequence":"additional","affiliation":[{"name":"University of Maryland, College Park"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elissa","family":"Redmiles","sequence":"additional","affiliation":[{"name":"Georgetown University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"35752","published-online":{"date-parts":[[2025,10]]},"container-title":["Proceedings on Privacy Enhancing Technologies"],"original-title":[],"deposited":{"date-parts":[[2025,7,13]],"date-time":"2025-07-13T15:58:34Z","timestamp":1752422314000},"score":1,"resource":{"primary":{"URL":"https:\/\/petsymposium.org\/popets\/2025\/popets-2025-0150.php"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,10]]}},"alternative-id":["10.56553\/popets-2025-0150"],"URL":"https:\/\/doi.org\/10.56553\/popets-2025-0150","relation":{},"ISSN":["2299-0984"],"issn-type":[{"value":"2299-0984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10]]}}}
