E?orts to defend against such attacks have, over the past several years, stimulated investigations into a new family of security protocols ¿ ¿Human Interactive Proofs¿ (HIPs) ¿ which allow a person to authenticate herself as a member of a given group: e.g., as a human (vs. a machine), as herself (vs. anyoneelse), as an adult (vs. a child). Most commercial usesofHIPstodayareCAPTCHAs,¿CompletelyAutomaticPublicTuringtests to tell Computers and Humans Apart,¿ which exploit the gap in ability between humans and machine vision systems in reading images of text. HIP challenges can also be non-graphical, e.g., requiring recognition of speech, solving puzzles, etc. Wearepleasedtopresentthe?rstrefereedandarchivallypublishedcollection of state-of-the-art papers on HIPs and CAPTCHAs. Each paper was reviewed by three members of the Program Committee, judged by the Co-chairs to be of su?cient relevance and quality, and revised by the authors in response to the referees¿ suggestions. The papers investigate performance analysis of novel CAPTCHAs, HIP - chitectures, and the role of HIPs within security systems. Kumar Chellapilla, Kevin Larson, Patrice Simard, and Mary Czerwinski describe user trials of a CAPTCHA designed to resist segmentation attacks, including a systematic evaluation of its tolerance by human users. Henry Baird, Michael Moll, and Sui- Yu Wang analyze data from a human legibility trial of another segmentati- resistantCAPTCHAandlocateahighlylegibleengineeringregime.AmaliaRusu and Venu Govindaraju describe research towards CAPTCHAs based on reading synthetically damaged images of real images of unconstrained handwritten text.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540260011\"\u003e\u003ch3\u003eSecond International Workshop, HIP 2005, Bethlehem, PA, USA, May 19-20, 2005, Proceedings\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540260011","offer_id":39425239122013,"sku":"9783540260011","price":53.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d7b6241a-859a-4928-a4a5-3db5f247ac7d.jpg?v=1773554655","url":"https:\/\/shop.autorenwelt.de\/products\/human-interactive-proofs-second-international-workshop-hip-2005-bethlehem-pa-usa-may-19-20-2005-proceedings-von-henry-s-baird-daniel-p-lopresti-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
