The first derived key is combined with the digital data to generate a protected record stored in the computer. Subsequently, the key derivation function is applied to a second value to generate a second derived key, the second value being equal to or derived from a second input password. The protected record is processed using the second derived key to permit access to the digital data when the second derived key matches the first derived key. The key derivation function includes iterations of a two-stage hashing operation creating and using an array of memory blocks whose size is specified independently of the number of iterations to decouple processing and memory requirements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer data protection using tunable key derivation function","description":"A computer-implemented method of protecting digital data includes applying a key derivation function to a first value to generate a first derived key, the first value being equal to or derived from a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9594918","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.
