Two or more of the multiple primitives are selected, and an operation is performed on the selected primitives, thereby defining a complex format. Upon and encryption processor receiving a data record comprising a plaintext, the complex format is applied to the plaintext, thereby generating a ciphertext, and the ciphertext is transmitted to a remote computer. Upon receiving the ciphertext, the remote computer can apply the complex format to the received ciphertext, thereby regenerating the plaintext."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Complex format-preserving encryption scheme","description":"Methods, computing systems and computer program products implement embodiments of the present invention that include defining multiple primitives, each primitive including ranking and unranking method","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634838","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.
