Cloud-Based Wi-Fi Authentication Using Personalized SSIDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi access point architectures lack efficient methods for providing credentials to foreign users, leading to wasted data rate and overloading of cellular networks due to inefficient authentication processes and lack of coordination, especially when networks are not occupied by pre-authorized users.
Innovation Solution
A cloud platform registers both client devices and Wi-Fi access points, allowing clients to identify and connect to target access points using pre-registered credentials, enabling authentication-free network login and sharing, and optimizing network usage through location detection and statistical analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional login-based mechanism with manual SSID and password sharing is used, then network security is maintained, but user convenience and connection speed deteriorate due to manual authentication requirements
Solution Approach 1:
The system performs preliminary registration of client devices with the Wi-Fi access point before actual connection is needed. During registration, the system pre-establishes credentials and stores them in a database, so that when a client needs to connect, authentication is instantaneous rather than requiring manual SSID and password entry at that moment
Solution Approach 2:
The invention introduces a database as an intermediary component that stores pre-registered credentials between the client devices and Wi-Fi access points. This mediator enables automatic authentication by retrieving pre-stored credentials, eliminating the need for manual authentication while maintaining security through the centralized credential management system
2Adaptability or versatility
If Wi-Fi access points broadcast beacons continuously to allow foreign users to connect, then network accessibility improves, but data rate efficiency deteriorates due to wasted bandwidth
Solution Approach 1:
The system enables self-service authentication where pre-registered client devices can automatically authenticate and connect to the Wi-Fi network without requiring continuous beacon broadcasts or manual intervention. The database stores credentials that allow clients to self-identify and connect efficiently, eliminating the need for continuous advertising while maintaining accessibility
Solution Approach 2:
Instead of continuous beacon broadcasting, the system uses periodic or event-driven authentication where the database checks for pre-registered clients only when connection requests are made. This transforms continuous resource consumption into periodic actions triggered only when needed, improving data rate efficiency while maintaining network accessibility
3Reliability
If MAC address authorization is used to control network access, then security is improved, but network utilization deteriorates when bandwidth is shared with unauthorized users
Solution Approach 1:
The invention introduces a database as an intermediary that manages credential verification between client devices and Wi-Fi access points. This centralized mediation enables flexible authorization policies where the system can distinguish between authorized and unauthorized users, allowing network owners to control access while optimizing bandwidth allocation based on registered users rather than relying on rigid MAC address filtering
Solution Approach 2:
The system changes the authorization parameter from static MAC address filtering to dynamic credential-based authentication stored in a database. This allows network owners to flexibly manage which devices are authorized, enabling better control over bandwidth sharing and network utilization while maintaining security through programmable authorization rules rather than fixed MAC address lists

AI summary
The invention provides a method and system for establishing a connection between a client device of a plurality of client devices and a Wi-Fi access point of a plurality of Wi-Fi access points using a cloud platform. To start with, the plurality of client devices and the plurality of Wi-Fi access points are registered with the cloud platform. Subsequently, the client device transmits a network demand request to one or more target Wi-Fi access points. The one or more target Wi-Fi access points receive account details containing pre-registered credentials associated with the client device from the cloud platform. Upon receiving the account details, the one or more target Wi-Fi access points authorize the client device and broadcast a personalized SSID. The client device uses the personalized SSID to access a Wi-Fi access point of the one or more target Wi-Fi access points using the pre-registered credentials.
