Cross-Network Authentication for Mobile Virtual Wallets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile subscribers face difficulties in using their home virtual wallets for services like mobile payments when traveling to foreign countries or zones, as foreign service providers cannot authenticate them, requiring the creation of a foreign virtual wallet and cumbersome money transfer processes.
Innovation Solution
A cross-network authentication method and system that allows mobile subscribers to authenticate and use foreign applications through data, voice, or WiFi roaming, enabling their home virtual wallets to function in foreign zones via a distributed transaction consensus network, such as blockchain, for digital property transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile subscribers use their home virtual wallet in foreign zones, then service accessibility is improved, but authentication reliability deteriorates because foreign service providers cannot authenticate subscribers from home carriers
Solution Approach 1:
The patent introduces a roaming authentication server as an intermediary component that bridges home carriers and foreign service providers. This server receives authentication requests from foreign service providers, validates subscriber credentials against home carrier databases, and returns authentication results. This intermediary mechanism enables foreign service providers to authenticate subscribers from home carriers without direct integration, thus improving service accessibility while maintaining authentication reliability.
2Adaptability or versatility
If mobile subscribers create foreign virtual wallets to use services in foreign countries, then service availability is improved, but device complexity and operational complexity increase due to multiple wallet management and cumbersome money transfer processes
Solution Approach 1:
The patent implements a universal roaming authentication mechanism that allows a single home virtual wallet to function across multiple foreign service providers and countries. The roaming authentication server enables the home virtual wallet to be recognized and accepted by foreign service providers without requiring subscribers to create separate foreign virtual wallets. This multi-functional approach maintains service availability in foreign countries while reducing wallet management complexity to a single universal wallet.
3Reliability
If traditional financial service providers are used for money transfer from home country to foreign virtual wallet, then transaction security is improved, but transaction time and operational complexity increase
Solution Approach 1:
The patent replaces the traditional mechanical money transfer system through banks and financial intermediaries with a direct digital property transfer mechanism enabled by blockchain technology. The distributed transaction consensus network allows for peer-to-peer value transfer between virtual wallets without requiring traditional banking channels. This substitution maintains transaction security through cryptographic verification and consensus mechanisms while dramatically reducing transfer time from days to near-instantaneous transactions.

AI summary
The described embodiments concern one or more methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps to authenticate mobile subscribers for using a foreign application when they are outside of their home telecom carrier's mobile network zone ("foreign zone"). A mobile subscriber can be authenticated through data roaming service, voice roaming service, and/or WiFi service. After cross network authentication, a mobile subscriber can use the foreign application to provide the same or similar services in a foreign zone, such as foreign country, through the home services in connection with the subscriber's home telecom carrier in a similar manner like he/she can use in his/her home zone, such as home country.
