Resumen de: AU2024258351A1

This invention pertains to the fields of distributed ledger, cryptocurrency, and decentralized physical infrastructure network. It solves the problems of the blockchain trilemma and cryptocurrency's lack of a real-world value that is recognizable to the mainstream population. Those two problems have prevented any cryptocurrency from gaining mass adoption. The Golf Ledger is distributed across a network of computers that are installed at up to 40,000 golf courses to leverage the existing decentralization of the world's golf courses and their ownership entry barrier and therefore does not need to sacrifice scalability for decentralization and security. The Golf Token as the native cryptocurrency of the Golf Ledger network is rewarded to golf courses for their contributing more and more computing resources to make the network more scalable. Their customers can use the Golf Token to pay golfing fees and get a discount, which is an obvious real-world value.

Resumen de: WO2025250373A1

A blockchain-based system and method for secure and auditable sharing of medical image studies between providers, patients, and authorized recipients. The system has modules for verifying identities of trusted healthcare providers as issuers of medical data, managing secure storage of medical images and metadata, minting non- fungible tokens (NFTs) representing patient ownership of studies, authenticating patient consent for data sharing, and controlling access to shared data by authorized parties. Issuer registration authenticates healthcare providers permitted to submit studies by verifying credentials against authoritative sources. Secure data management employs cryptographic wallets and smart contracts to ensure only verified issuers can create new medical data NFTs on the blockchain. Automated processing extracts medical data such as image files and metadata upon upload for separate secure storage, with metadata references encrypted in the associated NFT.

Resumen de: US2025371194A1

Method and apparatus for protecting confidential user data associated with a User. The user data are partitioned into portions which are stored in different memory locations, each portion insufficient to facilitate reconstruction of personally identifiable information without use of each of the remaining portions. A storage address for at least one portion is encoded and incorporated into a minted non-fungible asset (NFA) recorded to a distributed blockchain and placed in a User digital wallet. To subsequently reconstruct and access the user data, the storage address from the NFA is decoded, and the portions are retrieved from memory and recombined. A secure communication link facilitates authorized access to the reconstructed user data. Main and associated wallets may be used to track original and updated NFAs. The storage address may be in the Interplanetary File Storage (IPFS) system. The user data may be destroyed by erasing at least one portion from memory.

SYSTEM FOR FEDERATED COMPLIANCE-TOKEN INHERITANCE, DIGITAL ARTIFACT REGISTRY, AND MONETIZATION IN REGULATED ENVIRONMENTS USING LARGE LANGUAGE MODELS

NºPublicación:  US2025373432A1 04/12/2025

ONESOURCE SOLUTIONS INT INC [US]
OneSource Solutions International, Inc

Resumen de: US2025373432A1

A computerized platform enables secure, policy-compliant creation, governance, and monetization of digital artifacts produced by AI-driven “persona” agents in regulated domains (e.g., healthcare, finance). For each agent session, a federated compliance-token generator issues a cryptographically signed token embedding the full delegation chain, credential lineage, real-time policy snapshot, monetization rules, expiration and revocation data. As artifacts or workflows cross organizational or jurisdictional boundaries, a token inheritance module can subdivide, transfer, renew, or revoke the token while appending each event to an immutable, cryptographically linked audit trail. Every agent output is encapsulated as a digitally signed artifact that is indelibly linked to its originating compliance token and enriched with provenance, consent, and service metadata. A permissioned blockchain (or sharded distributed ledger) functions as an asset registry that immutably stores artifacts, tokens, and chronological records of creation, access, transfer, consent change, and policy updates. A smart-contract monetization engine allocates revenue or royalties based on artifact usage and institutional agreements, writing each billing event atomically to the ledger. Collectively, the system delivers continuous end-to-end traceability, privacy preservation, and automated financial settlement across diverse institutional boundaries.

Resumen de: US2025373456A1

This disclosure describes techniques for using a blockchain network to dynamically generate and transmit communications based on data stored on distributed records. The techniques described herein may enable an automated routine to store anonymized data on a distributed record and use such ledger data to determine whether and/or how to communicate with account holders. This enables the automated routine to avoid the need to decrypt data stored on distributed records before performing computations using the ledger data. Moreover, the techniques described herein enable an automated routine to use data stored on a public distributed record as a retrieval key for accessing a private backend database. This enables the automated routine to avoid the need to perform computationally resource-intensive operations to retrieve and/or interpret backend data beyond data queries. Accordingly, various aspects of the techniques described herein improve the computational efficiency of performing blockchain-based dynamic communication.

The present application discloses a data processing method, which is applied to a blockchain management system. The system comprises a first client, a second client, and a blockchain network, and a first smart contract is deployed on a plurality of chain nodes in a network. The method comprises: a first client uses a fully homomorphic public key issued by a sub-key group to encrypt first data, and then sends transaction information to a chain node, wherein the transaction information comprises a ciphertext of the first data; the chain node records the ciphertext of the first data in a blockchain ledger, and declares, by means of the first smart contract, that a data type of the ciphertext of the first data is a fully homomorphic ciphertext; and a second client sends an operation request to the chain node. The chain node performs a fully homomorphic operation on the ciphertext of the first data on the basis of the first smart contract and a fully homomorphic evaluation key issued by the sub-key group, and records the homomorphic operation result in the blockchain ledger. Thus, the security of data having high security requirements is guaranteed on the premise of not sacrificing the availability and operability of on-chain data.

Resumen de: US2024259269A1

Embodiments provide for the self-registration and automatic inventorying of enterprise Internet-of-Things (IoT) devices in an enterprise environment. An asset inventory agent on a network among many networks (i.e., within the enterprise environment) can receive a data packet from a computing device. The data packet is communicated via the network shared between the asset inventory agent and the computing device. The asset inventory agent can analyze the data packet, which can reveal a communication protocol associated with the computing device. A discovery rule associated with the protocol can be selected to extract inventory information from the data packet. The inventory information can be utilized to generate a distributed ledger transaction, which is communicated to a set of nodes adapted to collectively store the inventory information associated with the computing device onto the distributed ledger.
