Digital Wallet Token Authentication for Secure ID Access

The patent segments the digital wallet system into distinct functional modules: biometric authentication module, token generation module, credential storage module, and transaction processing module. Each module handles specific aspects of wallet operations independently, allowing security to be enhanced in one area without compromising accessibility in others. The biometric authentication separates identity verification from transaction execution, while tokens separate credential representation from actual sensitive data.

The patent introduces digital tokens as intermediaries between users and their credential data. Instead of directly exposing sensitive information, the system generates token representations that mediate access to actual credentials. These tokens act as secure proxies that can be transmitted and stored without revealing underlying sensitive data, thereby reducing security risk while maintaining ease of operation.

The patent implements a universal credential management system that can handle multiple types of credentials (government ID, insurance, loyalty programs, membership) through a single unified interface. The token generation mechanism is type-agnostic, creating standardized token representations that work across different credential categories. This allows the wallet to adapt to various identity providers and credential formats without requiring separate management systems for each type.

The patent transforms complex credential data into simplified token parameters. Instead of managing full credential datasets, the system converts credentials into token representations with essential parameters (token ID, issuer, validity period). This parameter transformation reduces the complexity of storing, transmitting, and managing multiple credentials while preserving their essential functions and adaptability.
