Smart Security Profile Recovery After Device Change Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to efficiently and securely transfer a profile between smart security media in case of movement failure during profile transfer between electronic devices.
Innovation Solution
A method and apparatus for recovering a profile involves transmitting a device change request to a server, deleting the profile from the first device, and requesting recovery of the deleted profile using a stored server address, ensuring seamless profile transfer even in failure scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If profile deletion is performed before confirming successful transfer to target device, then memory space is freed in source device, but profile loss occurs if transfer fails
Solution Approach 1:
The system performs preliminary actions by deleting the profile from the source device before confirming successful transfer to the target device. This is done in advance to free up memory space, but creates a risk if the transfer fails. The patent applies this by implementing a delete operation at the source device (first device) as a preliminary step before the profile is fully established at the target device (second device).
Solution Approach 2:
The patent implements beforehand cushioning by having the source device delete the profile in advance, assuming the transfer will succeed. This creates a cushioning effect where memory is freed proactively, but also creates a vulnerability if the transfer fails. The system cushions against memory constraints by prioritizing deletion over transfer confirmation.
2Productivity
If profile is deleted from source device to enable transfer, then memory is freed, but recovery becomes necessary if transfer fails
Solution Approach 1:
The system performs the deletion action preliminarily to enable efficient transfer. By deleting the profile from the source device before transfer completion, the system improves productivity by avoiding prolonged storage of redundant profiles. However, this preliminary deletion necessitates a recovery mechanism if transfer fails.
Solution Approach 2:
The patent introduces a server as an intermediary that stores profile information and facilitates recovery. When transfer fails, the server acts as a mediator to restore the profile to the source device. This intermediary mechanism adds complexity to the system architecture but enables efficient transfer operations.
3Ease of repair
If server address is stored in source device for recovery, then profile recovery is enabled, but security risk increases from storing external address
Solution Approach 1:
The system performs preliminary action by storing the server address in the source device before any transfer or recovery operations. This enables easy profile recovery by having the recovery endpoint pre-configured. However, this preliminary storage of external address information introduces security vulnerabilities that must be managed.
Solution Approach 2:
The source device performs self-service by storing its own recovery address locally. This enables the device to independently initiate recovery operations without external configuration. The self-service approach simplifies repair capability but requires careful management of the stored address data for security.
