A decryption of the colorgram is displayed on the first personal trusted device. An image is captured by a second personal trusted device. An encryption of the image captured from the second personal trusted device is uploaded to the transaction server. The persona descriptors are used to build a composite rendering for identification of the first user to the second user. The second user clicks “OK” if they recognize the composite drawing as a reasonable persona of the first user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile transaction methods and devices with three-dimensional colorgram tokens","description":"A transaction security process includes authentication and identification parts for pushing an encrypted colorgram for user authentication and persona descriptors for user identification from a transa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8478990","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.
