A microphone authentication apparatus (204) is described having a first input for receiving analogue audio signals from a microphone transducer (201) and an analogue-to-digital converter (202) coupled to said first input for generating digital microphone data based on the received audio signals. A data authentication module (203) generates an authentication certificate (MAC) for certifying that the digital microphone data did pass via the authentication module. The authentication certificate is based on the digital microphone data (DM) and an authentication module key. An output module outputs a digital microphone audio signal based on the digital microphone data with the authentication certificate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio data transfer","description":"This application relates to the transfer of audio data, and in particular to the verification that data transmitted to a data processing module, such as voice biometric module (111), did originate fro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11271756","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.
