The method requires a subject to present her face before a camera, which can be the built-in or peripheral camera of a mobile communication device. The method also requires displaying to the subject certain instructions and the real-time video feedback of the subject face on a display screen, which can be the built-in or peripheral display screen of the mobile communication device or mobile computing device. The 3D perspective check uses a single camera to take two images of the subject's face for the calculating the stereoscopic view data of the subject's face."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system of identification and authentication using facial expression","description":"The present invention employs a first step of stationary face recognition, followed by a facial expression test, a continuous movement tracking test, and a 3D perspective check to identify and authent","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9619723","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.
