Keychain Storage for Persistent Migration Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a home network controller management application is upgraded or an external server is replaced, existing systems fail to retain migration status information persistently, leading to user frustration as users must reimport data and reinitialize the application upon reinstall, causing a cumbersome experience.
Innovation Solution
The system utilizes keychain storage on a client device to persistently store application-specific initialization data, including migration status, ensuring that the application can quickly reinitialize with user data even after deletion and reinstall, providing a seamless user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If migration status information is stored in conventional storage areas, then the application can be reinitialized, but the information is lost when the application is deleted and reinstalled
Solution Approach 1:
The patent segments the storage area into two distinct parts: a conventional storage area for general application data and a keychain storage area specifically for migration status information. This segmentation allows the migration status to be preserved independently from the application installation state, solving the problem of information loss during reinstalls.
Solution Approach 2:
The keychain storage acts as an intermediary between the application and the persistent storage system. It stores migration status information in a protected manner that survives application deletion, effectively mediating between the temporary nature of application installations and the need for persistent status tracking.
2Ease of operation
If users manually reimport data after application reinstall, then data can be restored, but user time and effort are wasted
Solution Approach 1:
The system performs preliminary action by storing migration status information in the keychain before the application is deleted. When the application is reinstalled, this pre-stored information is automatically retrieved and used to restore the migration status, eliminating the need for users to manually reimport data and saving their time and effort.
3Reliability
If application data is stored in conventional memory, then storage is available, but data is not protected during application lifecycle changes
Solution Approach 1:
The storage architecture is segmented into conventional storage and keychain storage, with the keychain providing protected storage specifically for migration status. This segmentation adds a layer of protection without significantly complicating the overall storage architecture, as the keychain is a standard component in mobile devices.

AI summary
A system and a method are provided for a client device for use with a Wi-Fi network device, a first external server, and a second external server. The client device includes a memory having a non-critical portion configured to store non-critical data and a keychain storage portion configured to store encrypted data and a processor configured to execute instructions stored on the memory to cause the client device to: wirelessly associate with the Wi-Fi network device; store Wi-Fi network device data associated with configuring the Wi-Fi network device in the first external server; migrate the Wi-Fi network device data from the first external server to the second external server via the client device; and store migration status information in the keychain storage portion of the memory.
