The findings have been published today in\u00a0Nature Communications<\/p>\n<p>For the first time, the method provides a robust scientific framework for evaluating identification techniques, especially when dealing with large-scale data. This could include, for instance, monitoring how accurate advertising code and invisible trackers are at identifying online users from small pieces of information such as time zone or browser settings (a technique called \u2018browser fingerprinting\u2019).\u00a0<\/p>\n<p>Lead author\u00a0<a href=\"https:\/\/www.oii.ox.ac.uk\/people\/profiles\/luc-rocher\/\" target=\"_blank\" rel=\"noopener\">Dr Luc Rocher<\/a>, Senior Research Fellow at the Oxford Internet Institute, part of the University of Oxford, said:\u202f\u2018We see our method as a new approach to help assess the risk of re-identification in data release, but also to evaluate modern identification techniques in critical, high-risk environments. In places like hospitals, humanitarian aid delivery, or border control, the stakes are incredibly high, and the need for accurate, reliable identification is paramount.&#8217;<\/p>\n<p>The method draws on the field of Bayesian statistics to learn how identifiable individuals are on a small scale, and extrapolate the accuracy of identification to larger populations up to 10x better than previous heuristics and rules of thumb. This gives the method unique power in assessing how different data identification techniques will perform at scale, in different applications and behavioural settings. This could help explain why some AI identification techniques perform highly accurately when tested in small case studies but then misidentify people in real-world conditions.\u00a0\u00a0<\/p>\n<p>The findings are highly timely, given the challenges posed to anonymity and privacy caused by the rapid rise of AI-based identification techniques.\u202fFor instance, AI tools are being trialled to automatically identify humans from their voice in online banking, their eyes in humanitarian aid delivery, or their face in law enforcement.\u00a0<\/p>\n<p>According to the researchers, the new method could help organisations to strike a better balance between the benefits of AI technologies and the need to protect people&#8217;s personal information, making daily interactions with technology safer and more secure. Their testing method allows for the identification of potential weaknesses and areas for improvement before full-scale implementation, which is essential for maintaining safety and accuracy.\u202f\u00a0<\/p>\n<p>Co-author\u00a0<a href=\"https:\/\/cpg.doc.ic.ac.uk\/team\/yva\/\" target=\"_blank\" rel=\"noopener\">Associate Professor Yves-Alexandre de Montjoye<\/a>\u00a0(Data Science Institute, Imperial College, London) said: \u2018Our new scaling law provides, for the first time, a principled mathematical model to evaluate how identification techniques will perform at scale. Understanding the scalability of identification is essential to evaluate the risks posed by these re-identification techniques, including to ensure compliance with modern data protection legislations worldwide.\u2019\u202f\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>AI tools are increasingly being used to track and monitor us both online and in person, yet their effectiveness comes with big risks.\u202f Computer scientists at the University of Oxford have led a study to develop a new mathematical model that could help people better understand the risks posed by AI and assist regulators in\u2026<\/p>\n","protected":false},"author":2,"featured_media":19238,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_scj_primary_category_id":55,"_scj_featured":true,"_scj_featured_from":"","_scj_featured_until":"","_scj_featured_order":197,"_scj_visibility_class":"current","_scj_layout_family":"standard","_scj_article_style":"","_scj_display_overrides":[],"_scj_intro_image_id":19238,"_scj_intro_alt":"Pioneering new mathematical model could help protect privacy and ensure safer use of AI","_scj_intro_caption":"","_scj_intro_class":"","_scj_intro_float":"","_scj_full_image_id":19238,"_scj_full_alt":"Pioneering new mathematical model could help protect privacy and ensure safer use of AI","_scj_full_caption":"","_scj_full_class":"","_scj_full_float":"","_scj_media_type":"","_scj_media_provider":"","_scj_media_external_id":"","_scj_media_url":"","_scj_media_poster_id":0,"_scj_media_width":0,"_scj_media_height":0,"_scj_media_aspect_ratio":"","_scj_media_description":"","_scj_gallery_items":[],"_scj_related_post_ids":[],"_scj_additional_authors":[],"scj_layout_family":"standard","scj_media_provider":"","scj_media_url":"","scj_full_caption":"","footnotes":""},"categories":[55],"tags":[],"class_list":["post-19239","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-artificial-intelligence"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Pioneering new mathematical model could help protect privacy and ensure safer use of AI - thesmartcityjournal.com<\/title>\n<meta name=\"description\" content=\"For the first time, the method provides a robust scientific framework for evaluating identification techniques, especially when dealing with large-scale data.
