Methods, systems, and apparatuses are described herein for protecting the privacy of parties conducting Non-Fungible Token (NFT) transfers by conducting separate NFT transactions on a private blockchain separate from a public blockchain. An issuer and recipient may generate a token secret, and the issuer may send a create token transaction request comprising a unique token identifier, the token secret, and zero-knowledge proof data. Based on that request, an NFT may be minted on a private blockchain. A recipient may request the token by providing the unique token identifier and a zero-knowledge proof generated, by the recipient, based on the token secret. Based on comparing the zero-knowledge proof and the zero-knowledge proof data, the NFT may be sent to the recipient. A hash corresponding to a recipient address and the unique token identifier may be stored in a public blockchain.

Anonymous non-fungible token transfer using private blockchain

Embodiments disclosed are directed to a computing system that performs steps to automatically identify risk control features and entities in a risk control document. The computing system uses a generative machine learning (ML) model to transform a risk control document into sequences of words, classify risk control features associated with the sequences of words, and pair the sequences of words with the classified risk control features. The computing system then uses a natural language processing (NLP) model to identify syntactic characteristics of the sequences of words. Subsequently, the computing system uses a discriminative predictor system to correct the classified risk control features based on the identified syntactic characteristics, identify boundaries of the corrected classified risk control features, and pair the identified boundaries with the corrected classified risk control features.

Discriminative model for identifying and demarcating textual features in risk control documents

Embodiments disclosed are directed to a computing system that performs steps to automatically suggest a word, phrase, or entity to complete a sequence in a risk control document. The computing system classifies, by a generative machine learning (ML) model, risk control features associated with phrases in a risk control document. The computing system then generates, by the generative ML model and based on the classified risk control features, suggested words, phrases, or entities to complete a sequence following a cursor position in the risk control document. The computing system then corrects, by a discriminative natural language processing (NLP) model with domain specific knowledge, the suggested words, phrases, or entities. Subsequently, the computing system generates, by a discriminative predictor system, an encoded sequence of word, phrase, or entity suggestions based on the cursor position, the classified risk control features, and the corrected suggested words, phrases, or entities.
