Abstract
The present disclosure relates to methods and systems for recovering useable, secure and available key for blockchain applications. The method involves receiving an input story from a user that encapsulates a memorable life experience and processing this using a natural language processing (NLP) model to create a semantic embedding vector. Additionally, the method optionally collects a biometric sample to produce biometric embedding, which is combined with semantic embedding. Locality-sensitive hashing (LSH) is applied to this combined embedding to create a fixed-length bitstring, which is then processed through a fuzzy extractor to produce a stable, cryptographically strong key for securing digital assets.
