The root node entry point is calculated based on the access data by means of a predeterminable calculation function in a volatile way, and the root node entry point represents a secret node entry point from which the identification value of a root node of the tree is subsequently calculated. The root node represents one of the child nodes in this tree, as a child node generation step is applied to generate the identification values of the child nodes based on one of the secret node entry points. A child node numbering set contains at least as many different elements as the number of child nodes to be generated is created or used."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for generating metadata-free trees","description":"A method for storing hierarchical data protected by access data in an untrustworthy environment, wherein unique identification values of child nodes of at least one associated tree are determined for ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520921","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.
