The method comprises extracting frequency domain data from an image of the target authentication device to facilitate verification of authenticity of the target authentication device. The method provides a very effective end expedient mechanism for verifying authenticity of a moiré or moiré like authentication device to combat counterfeiting."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication apparatus and methods","description":"A method of and an apparatus for verifying authenticity of a target authentication device comprising a reference pattern having a characteristic frequency and a security pattern, the security pattern ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9633195","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.
