Cellular Wallet Transfer Using Temporary Wallets and Presigned Transactions

The system enables self-service authentication where the cellular device automatically manages wallet access without requiring user intervention for authentication. The device uses its own authentication mechanisms (biometric, PIN, or other device-based methods) to automatically authenticate wallet transactions, eliminating the need for users to manually enter passwords or passkeys while maintaining security through the device's built-in authentication services.

The patent extracts the wallet administration function from centralized servers and relocates it to the user's cellular device. Each device becomes an independent wallet administrator that locally manages private keys and authentication, eliminating the centralized point of failure that is vulnerable to hacking. The device uses its own secure enclave or hardware security module to store and manage cryptographic credentials, ensuring that even if the network is compromised, the wallet remains secure.

The system leverages the cellular device's existing multi-functional authentication capabilities (biometric sensors, hardware security modules, PIN entry mechanisms, and network communication) to serve the wallet authentication function. Rather than implementing dedicated complex authentication hardware, the patent reuses the device's universal authentication infrastructure that already exists for locking the device, enabling two-factor authentication, and other security functions, thereby avoiding additional complexity while maintaining strong security.
