A method for authenticating an electronic image of a document comprises receiving the electronic image of the document and a profile tracing signature of a surface of the document that is associated with the electronic image, and comparing the profile tracing signature with an exemplar profile tracing signature associated with the document. A document processing system comprises a pickup, a signal processing circuit, and a scanning module and is used for producing a profile tracing signature and electronic image of a document and for correlating the profile tracing signature with the electronic image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface profile tracing of a document","description":"A method for providing an indication of authenticity of an electronic image of a document comprises generating a signal corresponding to a profile of at least one of a number of surfaces of the docume","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8504828","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.
