The invention relates to a computer-implemented platform for managing the leasing of real estate assets through automated tenant-landlord verification, dynamic risk scoring, and smart contract execution. Tenant and landlord accounts are established via Know Your Customer (KYC) protocols. Tenant creditworthiness scores are computed using financial, employment, and behavioral data, and matched against landlord-defined eligibility thresholds. Lease agreements are executed via blockchain-based smart contracts, ensuring immutable, enforceable records. Rental deposit requirements are dynamically calculated based on tenant risk profiles and lease conditions, and may be fulfilled either through a real-time, event-driven insurance instrument or through financing from an authorized third-party financial institution. The insurance instrument is calibrated algorithmically to reflect changing risk exposure, behavioral history, and contextual data, thereby enabling dynamic collateralization of lease obligations. The platform further comprises modules for structured damage reporting, automated maintenance escalation, dispute resolution workflows, and landlord reputation scoring. All transactional events are logged in a tamper-evident ledger. The system also supports data export and third-party integration with financial institutions, insurers, and regulatory platforms via secure APIs and analytics dashboards.

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.

The present invention relates to a method and a system for restoring a private key by using multi-biometric information. In the storing of a private key of a user in a blockchain network, multi-biometric information, which indicates the uniqueness of the user by being collected when the user utters a script or inputs authentication information, is stored together. When the user loses the private key, the user is prompted to re-utter the script and input the authentication information, thereby verifying whether the user who initially generated the private key is the same as the user who lost the private key and requests private key restoration, and, if the users are identical to each other, the private key is restored using the multi-biometric information of the user.

Methods, systems, and devices for entity token segregation are described. A custodial token platform (e.g., via a ledger service or manager) monitors a set of actions by a first set of user profiles at a custodial token platform based on the first set of user profiles being associated with a first segregated entity for which a rebalancing rule is configured. The custodial token platform determines, based on the rebalancing rule, a net change in token amounts attributed to the first set of user profiles associated with the first segregated entity during a first duration of time. The custodial token platform executes a transfer of a first amount of one or more crypto tokens between a first blockchain address associated with the first segregated entity and a second blockchain address associated with the custodial token platform, where the first amount is based on the rebalancing rule and the net change.

NFTs are used to provide software licensing and DRM in a manner that is transferrable, allowing licensees to swap and resell licensed software according to terms specified by the licensor. NFTs are used to prove ownership of software and other digital assets on a blockchain. The blockchain provides a distributed public ledger that enables the tracking of ownership of the assets, without the use of a centralized server. Since software and other digital content licenses concern digital assets, they can be granted, tracked, and revoked on the blockchain via the use of NFTs. NFTs and the blockchain therefore provide a mechanism which is used to verify and authenticate software licenses, digital content licenses, and other types of licenses for digital assets. Smart contracts may be used to define and enforce the terms of the licenses, at any level of granularity.
