The first and second signals are used to determine a location of an apparent source of the received sound. It is determined that the received sound may result from a replay attack if the apparent source of the received sound is diffuse."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of replay attack","description":"In order to detect a replay attack on a voice biometrics system, a first signal from received sound is generated at a first microphone, and a second signal from the received sound is generated at a se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11276409","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
