Gateway Cookie Authentication Across Device Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network authentication methods fail to effectively identify and authenticate users when they switch from one device to another, especially when the new device lacks cookie-handling capabilities, leading to loss of session data and authentication issues.
Innovation Solution
A gateway server with enhanced cookie-handling capabilities generates and manages gateway cookies that can be stored on mobile devices, allowing seamless authentication and identification across different devices, including those without cookie-handling capabilities, by storing and transferring cookies between devices securely within the mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device connects to a mobile network using traditional authentication methods, then the device can access network resources, but the authentication credentials are device-specific and cannot be transferred to another device
Solution Approach 1:
The patent implements a cookie transfer mechanism where authentication credentials are copied from a first mobile device to a second mobile device. The gateway server generates a cookie containing authentication information on the first device, transfers it to the second device, allowing the second device to present these credentials to the gateway server for authentication without requiring separate credentials.
2Reliability
If a gateway server generates and transfers cookies between devices, then authentication can be preserved across device changes, but devices without cookie-handling capabilities cannot store or transfer cookies
Solution Approach 1:
The gateway server acts as an intermediary that handles cookie generation, storage, and transfer. For devices without cookie-handling capabilities, the gateway server stores the cookie on its own side and manually transfers it to the new device during authentication processes, eliminating the need for the device to independently manage cookies.
Solution Approach 2:
The gateway server implements multiple functions: it serves as an authentication server, a cookie manager, and a transfer mechanism. This universal approach allows it to handle both devices with cookie-handling capabilities and devices without such capabilities, making the authentication system universally applicable across different device types.
3Ease of operation
If authentication credentials are stored locally on each mobile device, then each device can independently authenticate, but switching devices results in loss of session data and authentication credentials
Solution Approach 1:
The system copies authentication credentials from local storage on the first device to the second device through the gateway server. The cookie containing session information is extracted from the first device's local storage, transferred through the gateway server, and stored on the second device, preventing information loss during device switching.
Solution Approach 2:
The gateway server performs preliminary actions by generating and storing backup copies of authentication credentials before device switching occurs. When a user indicates intent to switch devices, the credentials are already prepared and can be quickly transferred, minimizing disruption and preventing data loss.
Data Source
AI summary
Cookies differentiate users and maintain data related to a user during navigation. Cookies are used for activities such as authenticating, session tracking, and maintaining specific information about users. An embodiment receives a first access request from a mobile device that corresponds to a first attempt by the mobile device to access the mobile network. The mobile device is authenticated using a set of authentication credentials provided by the mobile device. A gateway cookie is created that includes a second set of authentication credentials associated with the mobile device. The gateway cookie is provided to the mobile device and stored on the mobile device. A second access request, received from the mobile device, includes the gateway cookie and the second access request corresponds to a second attempt by the mobile device to access the mobile network. The mobile device is authenticated using the gateway cookie.
