RECORD-LEVEL ENCRYPTION SCHEME FOR DATA OWNERSHIP PLATFORM

Resumen de: WO2026003719A1

Disclosed herein are embodiments for a record-level encryption scheme. A data visibility control platform may facilitate record-level encryption between a data owner device and a requester device, requesting access to the encrypted record.

The data visibility control platform may use a combination of private and public cryptographic keys associated with the data owner and requester to provide record-level encryption. An embodiment may include record keys used to encrypt records being stored by a records database managed by a data intermediary. The record key may be encrypted using the public key of the data owner and stored on a blockchain. Access to the record key stored on the blockchain is controlled by the data owner.

SYSTEM AND METHOD FOR OFFLINE PAYMENT ON A BLOCKCHAIN

Resumen de: WO2026005597A1

Computer-implemented methods and a system are presented for offline payments between nodes. The method includes setting up a vouching agreement between a first and a second node and locking a vouched amount of tokens at the first node for use by the second node. An offline transaction is performed between the second and a third node, wherein the offline transaction exceeds a second amount of tokens available to the second node. While offline, the second node uses the vouched amount to perform the offline transaction with the third node. When online again, the second node reconciles the vouched amount with the first node. If the second node does not pay back the vouched amount to the first node, a reputation score of the second node is decreased. If the second node pays back the vouched amount to the first node, reputation scores of the first and the second node are increased.

SECURE TRANSACTION AUTHORIZATION

Resumen de: US20260004285A1

Secure blockchain (BC)-based tokens are issued and linked to payment cards and/or devices of customers. Custom conditions associated with the tokens are stored in smart contracts on a BC. The tokens are stored in a cloud-based key vault and/or in the BC. Validation of a token for access a smart contract on the BC can only be made by a financial institution (FI) to the key vault. Real-time information for a transaction device, for transaction information, and/or for the customer is provided as input data to the smart contract for evaluation of the conditions. After the token is authenticated by the key vault, the real-time information is gathered and passed to the corresponding smart contract on the BC for evaluation. The FI receives transaction authorization or transaction denial based on the smart contract's evaluation of the conditions.

Off-Chain Gas Management System and Method

Resumen de: US20260004289A1

An off-chain gas management system allows Web3 developers to cover gas fees for their users. When a user wants to complete a blockchain transaction, the system receives a sponsorship request through an API and checks if the operation qualifies under the developer's gas sponsorship policy. Policies include spending limits, approved addresses, and time restrictions. If approved, the system creates a cryptographic signature that authorizes transfer of the gas fee amount. An on-chain contract validates the signature before covering the gas fees. The system includes a user interface for creating and managing policies with configurable spending controls and address restrictions. Advanced features use machine learning to allocate funds based on user value, detect fraud, classify transaction types, optimize cryptocurrency purchases, and predict when funds will run out. This eliminates the barrier of users needing to own cryptocurrency to pay gas fees while maintaining security through automated policy enforcement and cryptographic validation.
