The permuted keyword strings are encrypted using an order preserving encryption algorithm or a modular order preserving encryption algorithm and stored in the permuterm index. In response to a search query containing a wildcard search term, the encrypted text wildcard search method transforms the wildcard search term to a permuted search term having a prefix search format. The permuted search term having the prefix search format is then used to perform a range query of the permuterm index to retrieve permuted keyword strings having ciphertext values that fall within the range query. In some embodiments, the encrypted text wildcard search method enables prefix search, suffix search, inner-wildcard search, substring search and multiple wildcard search of encrypted text."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wildcard search in encrypted text using order preserving encryption","description":"A encrypted text wildcard search method enables wildcard search of encrypted text by using a permuterm index storing permuted keyword strings that are encrypted using an order preserving encryption al","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9760637","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.
