Applicable for complex project management where frequent changes and large number of people are involved. Also in email systems where a single email will deliver a shared message plus individual messages to selected readers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Document management cryptography","description":"Using composite cipher technology a single ciphertext C will decrypt to plaintext Pi using key Ki, and to plaintext Pj≠Pi using key Kj≠Ki, thereby a single file C will carry any number of distinct mes","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290253","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.
