A first chain of trust between the first work step and the second work step can be defined by defining a second manifest document that is associated with the second data product and that references a first manifest document associated with the first data product. An immutable data structure representing a second chain of trust independent of the first chain of trust can be defined by submitting the first manifest document and the second manifest document to a distributed ledger for validation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for producing data structures having internal self-references suitable for immutably representing and verifying data","description":"Some embodiments described herein relate to a computer implemented method that includes performing a first work step associated with a first activity and with a first data product and performing a sec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11494402","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.
