Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

When a user switches from a mobile device capable of handling cookies to one that is not, existing technologies fail to preserve cookies stored on the gateway server, resulting in loss of session information and authentication credentials.

Innovation Solution

A gateway server is implemented with enhanced cookie-handling capabilities, storing cookies associated with a user's identifier and transferring them to the new device upon request, ensuring seamless cookie preservation across different devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cookies are stored on a mobile device that does not have cookie-handling capability, then the device cannot preserve session information, but if cookies are stored on the gateway server, then device switching becomes possible while preserving session information

Engineering Contradiction:

Improvedevice switching capabilityVSAvoidsession information loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The gateway server acts as an intermediary between mobile devices and the IP network, specifically serving as a cookie manager for devices lacking cookie-handling capabilities. It stores cookies associated with device identifiers and provides them to authorized devices, enabling seamless device switching while preserving session information.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution moves cookie storage from the device dimension (local storage) to the network dimension (gateway server storage). This dimensional shift allows cookies to be preserved independently of any specific device, enabling device switching while maintaining session continuity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If cookies are transferred to a new mobile device, then session continuity is maintained, but security risks increase if proper authentication is not implemented

Engineering Contradiction:

Improvesession continuityVSAvoidsecurity risks

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The gateway server performs preliminary authentication of the new mobile device before transferring cookies. It verifies that the requesting device is authorized to receive the cookies associated with a particular user, preventing unauthorized access while enabling legitimate device switching.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the gateway server receives authentication responses from the new device and uses this feedback to determine whether cookie transfer should proceed. This ensures that only authenticated devices can access stored cookies.

Inventive Principle:

Principle #23Feedback

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 facilitates a method of preserving cookies associated with a first mobile device operated by a user who begins using a second mobile device. The method includes receiving a plurality of cookies associated with the first mobile device and storing the cookies in a data store associated with a gateway server. A cookie request is received from the second mobile device and the cookies are provided to the second mobile device.
