Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Secure elements in electronic devices lack a backup function, requiring reinstallation and data loss when transitioning to new devices, necessitating manual reinstallation of content applications and data.
Innovation Solution
Incorporating a secure element with backup data and a backup application that allows encrypted data to be loaded, transmitted, and decrypted for reinstallation on new devices, enabling seamless data restoration and initialization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secure element stores backup data for content applications, then data restoration capability is improved, but device complexity increases
Solution Approach 1:
The patent implements backup data storage by nesting the backup function within the existing secure element structure. The secure element, which already stores content applications, is extended to also store backup data of these applications, creating a nested storage architecture where backup data is integrated within the secure element's storage capacity rather than requiring separate backup infrastructure.
Solution Approach 2:
The secure element is designed to perform multiple functions: storing content applications, storing backup data of content applications, and enabling data restoration. This multi-functional approach allows the same hardware component to handle both application storage and backup operations, reducing the need for additional dedicated backup hardware.
2Reliability
If manual reinstallation is required for content applications, then device security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary backup of content application data within the secure element before device transitions or data loss scenarios occur. This pre-stored backup data can then be automatically restored without requiring manual reinstallation, thus maintaining security while improving ease of operation during device changes.
Solution Approach 2:
The secure element enables self-service data restoration by automatically providing backup data to the electronic device when needed. The system can autonomously restore content applications from the stored backup data without requiring user intervention for manual reinstallation, while still maintaining security through the secure element's protected environment.
3Reliability
If all data is removed for data restoration, then data integrity is improved, but loss of information increases
Solution Approach 1:
The patent extracts only the necessary backup data from the secure element for restoration purposes, rather than removing all data from the system. This selective extraction approach allows restoration of specific content applications while preserving other data, thus maintaining data integrity for restored applications while minimizing overall information loss.
Solution Approach 2:
The system recovers lost or corrupted content application data by utilizing the stored backup data in the secure element. Instead of discarding all data and starting fresh, the system selectively recovers only the necessary backup information, thereby maintaining data integrity for restored applications while avoiding unnecessary loss of other preserved data.
Data Source
AI summary
According to certain embodiments, an electronic device comprises: a secure element storing at least one content application and backup data associated with the at least one content application; a memory storing instructions; and a processor electrically connected to the secure element and the memory and configured to executed the instructions, wherein execution of the instructions by the processor causes the processor to perform a plurality of operations comprising: when receiving a message requesting a backup operation from an external electronic device, loading encrypted backup data from the secure element, transmitting the backup data to the external electronic device, and when receiving a message about backup completion from the external electronic device, setting the backup data to an unavailable state.
