Mobile Authentication Security Validator with Proxy Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication processes on mobile devices lack robust integrity measures, particularly against phishing attempts, malware, and unauthorized access, leading to potential security breaches.
Innovation Solution
Implementing a security validator on the mobile device that intercepts authentication requests, applies security conditions, and blocks or forwards them based on validation, utilizing a proxy server to route authenticated traffic through a dedicated IP address, and a VPN component for deep packet inspection and policy-based traffic manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security validator is added to intercept and validate authentication requests, then authentication integrity is improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into distinct functional components: an authentication client for handling authentication logic, a security validator for security checks, and a proxy server for traffic routing. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by distributing responsibilities clearly.
Solution Approach 2:
A proxy server is introduced as an intermediary between the mobile device and the authentication server. The proxy server receives authentication requests from the device, validates them through the security validator, and forwards approved requests to the authentication server. This intermediary layer isolates security validation logic from the core authentication flow, reducing direct system complexity.
2Reliability
If multiple security conditions are applied to validate authentication requests, then security against phishing and malware is improved, but processing time increases
Solution Approach 1:
Security conditions are evaluated in advance before the authentication request reaches the authentication server. The security validator performs preliminary checks on device security state, network location, and traffic patterns, so that when the authentication server receives the request, the security assessment is already complete, reducing overall processing time.
Solution Approach 2:
The security validator continuously monitors device security state and network conditions, providing feedback to the authentication client and proxy server. This feedback mechanism allows the system to adapt validation strictness based on current security conditions, reducing processing time when risks are low while maintaining thorough validation when threats are detected.
3Reliability
If a proxy server is used to route authentication traffic, then authentication integrity is improved, but network infrastructure complexity increases
Solution Approach 1:
The proxy server is designed to perform multiple functions: it routes authentication traffic, validates security conditions, inspects packets deeply, and can block malicious requests. By combining these functions into a single multi-functional component, the system reduces the need for separate infrastructure elements, thereby limiting the increase in network infrastructure complexity.

AI summary
A method of performing user authentication by a mobile device with an authentication client and an authentication server with a rules engine. A security validator intercepts an authentication request sent by the client to the server and validates the authentication request by applying security conditions to it. The security validator blocks the request or forwards the request according to the validation. The system includes a proxy server, and if validation is positive the validator sends the authentication request to the proxy server and the proxy server routes it on to the authentication server. In this case the authentication client is disabled from directly routing an authentication request to the authentication server if the security validator is not present or is tampered with.
