Portable Access Point for Secure User Information Using a Blockchain Backed Credential

Resumen de: US2025385915A1

Embodiments dynamically generate a portable access point.

INTELLIGENT AI ROUTING ADVISORY PLATFORM WITH SYNTHETIC INJECTION TESTING, BIAS DETECTION DIGITAL TWIN, ZERO-COPY PIPELINE, CRYPTOGRAPHIC COMPLIANCE VERIFICATION, AND AUTONOMOUS MULTI-TIER COORDINATION FOR HETEROGENEOUS AI PROVIDER ECOSYSTEMS

Resumen de: US2025385797A1

A computer-implemented system for routing artificial intelligence (AI) queries. The system utilizes a zero-copy data pipeline, which processes prompts in memory-mapped buffers to eliminate at least one memory copy operation, thereby reducing latency relative to conventional serialization pipelines. The system continuously verifies AI provider compliance by injecting synthetic prompts containing invisible, Ed25519-signed Unicode watermarks. Algorithmic bias is detected by generating counterfactual “digital twin” prompts and applying Fisher exact statistical testing.Routing decisions for multi-tier autonomous systems are governed by safety-level requirements (ASIL-D, ASIL-B, QM) and may be constrained by external routing directives received via a meta-identifier. A hash-chained manifest, cryptographically signed using Ed25519 and consumed by downstream gateways, is generated for each routing decision, with its Merkle root asynchronously anchored to a blockchain to create a tamper-evident audit trail for regulatory compliance.

Intelligent Adaptive Asset Leasing System with Dynamic User Profiling, Risk Management, and Insurance Frameworks

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.

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.
