DOR LAVI ZOHAR [CH]
Dor Lavi Zohar

Resumen de: US2025378511A1

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.
