It uses risk analysis and challenge-based verification to help organizations identify automated activity and suspicious behavior. <\/p>\n<p>The service is commonly deployed on login pages, registration forms, password reset pages, and checkout systems, where it can allow an interaction to proceed, require additional verification, or block the request.<\/p>\n<p>How hand gesture verification works<\/p>\n<p>When the hand gesture feature is enabled, reCAPTCHA analyzes one or more videos of a user\u2019s hand as they perform prompted gestures. The videos are processed to extract hand landmark data, including 21 hand-knuckle coordinates.<\/p>\n<p>Google <a href=\"https:\/\/docs.cloud.google.com\/recaptcha\/docs\/hand-gesture-verification\" target=\"_blank\" rel=\"nofollow noopener\">says<\/a> the videos are not associated with a user\u2019s identity, audio is not recorded, and the videos are deleted after the verification process.<\/p>\n<p>Hand gesture verification requires camera access and prompts users to perform specific gestures. The videos are processed only for security verification, camera permissions can be revoked at any time, and related data is not shared with third parties.<\/p>\n<p>Users who cannot complete hand gesture verification because of accessibility needs can continue using reCAPTCHA\u2019s visual and audio challenges. Google says it is developing additional accessibility-focused verification methods.<\/p>\n","protected":false},"excerpt":{"rendered":"Google has introduced hand gesture verification for reCAPTCHA, a new method for verifying that a user is human.&hellip;\n","protected":false},"author":2,"featured_media":543409,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[74],"tags":[76263,18,12668,823,4830,233146,19,17,82],"class_list":["post-543408","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-data-collection","tag-eire","tag-fraud","tag-google","tag-google-cloud","tag-identity-protection","tag-ie","tag-ireland","tag-technology"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116776576938158955","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/543408","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=543408"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/543408\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/543409"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=543408"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=543408"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=543408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
