The metrics analyzed include Biometric Matching (before and after cloaking) and Irreversibility, with a focus on Specific Absorption Rate (SAR). Furthermore, the document assesses Unlinkability between different systems (sys D and sys M), reporting low values for both ArcFace and FaceNet, indicating a high degree of unlinkability due to cloaking. The data suggests that while both methods offer strong privacy preservation, ArcFace generally maintains a slight edge in matching accuracy after cloaking. Notably, the irreversibility metric (SAR) is consistently 0.0% for both, implying complete irreversibility, a crucial aspect of privacy-preserving systems. The unlinkability measures demonstrate significant improvements with cloaking, particularly for FaceNet, although ArcFace still shows superior performance in this regard. Detailed numerical data is provided in tabular format for clear comparison.","| Metric  |  | Description | ArcFace | FaceNet |\n| --- | --- | --- | --- | --- |\n| Biometric\u003Cbr>Matching |  | Before Cloaking | 96.2% | 69.3% |\n|  |  | After Cloaking | 95.7% | 67.8% |\n\n\n| Irreversibility  |  | SAR | 0.0% | 0.0% |\n| --- | --- | --- | --- | --- |\n| Unlinkability |  | sys D ←−−→− | 0.003 | 0.03 |\n|  |  | sys M ←−−→− | 0.007 | 0.11 |","cbCaiq1yYQ2TmIBu","https://ap.wps.com/l/cbCaiq1yYQ2TmIBu","pdf",1224507,5,"English","en",105,"# Metric Analysis\n## Biometric Matching\n### Before Cloaking\n### After Cloaking\n## Irreversibility\n## Unlinkability","[{\"question\":\"What are the main biometric matching metrics evaluated in this document?\",\"answer\":\"The document evaluates Biometric Matching, Irreversibility, and Unlinkability for privacy-preserving techniques.\"},{\"question\":\"How does cloaking affect the biometric matching accuracy of ArcFace and FaceNet?\",\"answer\":\"Cloaking slightly reduces the biometric matching accuracy for both ArcFace (from 96.2% to 95.7%) and FaceNet (from 69.3% to 67.8%).\"},{\"question\":\"What is the reported SAR value for Irreversibility?\",\"answer\":\"The Specific Absorption Rate (SAR) for Irreversibility is reported as 0.0% for both ArcFace and FaceNet, indicating complete irreversibility.\"}]","Privacy Preserving Biometric Matching and Evaluation | PDF",1788387781,2,{"code":4,"msg":31,"data":32},"ok",{"site_id":24,"language":23,"slug":33,"title":14,"keywords":34,"description":15,"schema_data":35,"social_meta":86,"head_meta":88,"extra_data":90,"updated_unix":28},"privacy-preserving-biometric-matching-and-evaluation","",{"@graph":36,"@context":85},[37,53,68],{"@type":38,"itemListElement":39},"BreadcrumbList",[40,44,47,50],{"item":41,"name":42,"@type":43,"position":11},"https://docshare.wps.com","Home","ListItem",{"item":45,"name":46,"@type":43,"position":29},"https://docshare.wps.com/template/","Template",{"item":48,"name":13,"@type":43,"position":49},"https://docshare.wps.com/template/general/",3,{"item":51,"name":14,"@type":43,"position":52},"https://docshare.wps.com/template/privacy-preserving-biometric-matching-and-evaluation/188191/",4,{"url":51,"name":14,"@type":54,"author":55,"headline":14,"publisher":57,"fileFormat":60,"inLanguage":23,"description":15,"dateModified":61,"datePublished":62,"encodingFormat":60,"isAccessibleForFree":63,"interactionStatistic":64},"DigitalDocument",{"name":9,"@type":56},"Person",{"url":41,"name":58,"@type":59},"DocShare","Organization","application/pdf","2026-09-06","2026-09-02",true,{"@type":65,"interactionType":66,"userInteractionCount":11},"InteractionCounter",{"@type":67},"ViewAction",{"@type":69,"mainEntity":70},"FAQPage",[71,77,81],{"name":72,"@type":73,"acceptedAnswer":74},"What are the main biometric matching metrics evaluated in this document?","Question",{"text":75,"@type":76},"The document evaluates Biometric Matching, Irreversibility, and Unlinkability for privacy-preserving techniques.","Answer",{"name":78,"@type":73,"acceptedAnswer":79},"How does cloaking affect the biometric matching accuracy of ArcFace and FaceNet?",{"text":80,"@type":76},"Cloaking slightly reduces the biometric matching accuracy for both ArcFace (from 96.2% to 95.7%) and FaceNet (from 69.3% to 67.8%).",{"name":82,"@type":73,"acceptedAnswer":83},"What is the reported SAR value for Irreversibility?",{"text":84,"@type":76},"The Specific Absorption Rate (SAR) for Irreversibility is reported as 0.0% for both ArcFace and FaceNet, indicating complete irreversibility.","https://schema.org",{"og:url":51,"og:type":87,"og:title":14,"og:site_name":58,"og:description":15},"article",{"robots":89,"canonical":51},"index,follow",{"doc_id":7,"site_id":24},{"code":4,"msg":5,"data":92},[93,98,103,108,113,118,123,128,132],{"id":94,"doc_module":11,"doc_module_name":46,"category_name":95,"show_sort_weight":96,"slug":97},11,"Presentations",90,"presentations",{"id":99,"doc_module":11,"doc_module_name":46,"category_name":100,"show_sort_weight":101,"slug":102},12,"Resumes",80,"resumes",{"id":104,"doc_module":11,"doc_module_name":46,"category_name":105,"show_sort_weight":106,"slug":107},14,"Invoices",70,"invoices",{"id":109,"doc_module":11,"doc_module_name":46,"category_name":110,"show_sort_weight":111,"slug":112},15,"Posters",60,"posters",{"id":114,"doc_module":11,"doc_module_name":46,"category_name":115,"show_sort_weight":116,"slug":117},16,"Social Media",50,"social-media",{"id":119,"doc_module":11,"doc_module_name":46,"category_name":120,"show_sort_weight":121,"slug":122},17,"Forms",40,"forms",{"id":124,"doc_module":11,"doc_module_name":46,"category_name":125,"show_sort_weight":126,"slug":127},18,"Letters",30,"letters",{"id":129,"doc_module":11,"doc_module_name":46,"category_name":130,"show_sort_weight":21,"slug":131},21,"Paper Templates","papers-templates",{"id":12,"doc_module":11,"doc_module_name":46,"category_name":13,"show_sort_weight":4,"slug":133},"general-158"]
