Resumen de: US20260322612A1
0000 A secure cryptocurrency system comprising a tamper-resistant hardware device that generates dynamic passwords at predetermined time intervals while maintaining encrypted storage of authentication credentials. The device integrates multiple biometric sensors including fingerprint, retinal scan, and heartbeat pattern recognition to provide multi-modal authentication that eliminates static password vulnerabilities. The system stores devices in secure vault facilities at financial institutions with controlled access, creating “multiple redundancies across different locations” for continuity. A biometric fusion processor generates unified authentication decisions based on user-configurable security thresholds, implementing “tiered security” that varies access permissions based on cryptocurrency transaction amounts. The device includes fail-safe mechanisms that automatically disable upon tampering detection. Dynamic passwords display temporarily before automatically hiding, enabling “checking account functionality” through banking infrastructure integration while maintaining offline security.

The compositions and methods described herein relate to authentication using Sid4CID substances—customized stable isotopes, rare earth elements, and precision-engineered compounds—optionally combined with CLR colorants formulated from diverse molecular combinations. These traceable taggants are incorporated at trace-level concentrations through various application modalities and integrated pathways into commercial materials or coatings. CLR compounds encompass a diverse spectrum of engineered colorant systems, designed to maintain detectability and functional integrity across varied chemical environments and coating architectures. The incorporation of taggants enables detection through a range of analytical technologies, spanning non-destructive field instruments and advanced laboratory-based assays. The system supports anomaly detection, digital governance, and blockchain-based traceability through structured APIs and secure platforms. Sid4CID-CLR materials and coatings function as covert markers for identity, provenance, and anti-counterfeiting, enhancing compliance and intellectual property protection across commercial domains.

A system and method may leverage Gen AI to prevent future digital transactions by fraudulent actors using digital avatars of an expired entity. A proof of death may be generated for an expired entity, such as a deceased person, and recorded on the blockchain. An avatar associated with the expired entity may control digital assets or rights associated with the avatar. The avatar of the expired entity may be caused to expire to prevent future use by generating an electronic proof of expiry of the avatar that is recorded in a blockchain ledger or in an avatar repository. A beneficiary of assets or rights controlled by the expired avatar may be determined. When there is no nominee, an NFT that indicates that there is no nominee may be recorded on the blockchain, and legal authorities may handle the disposition of the assets or rights of the expired avatar.
