Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If memory information is stored in a cloud or electronic device, then users can access information conveniently, but security risks increase and personal information may be exposed
Solution Approach 1:
The patent segments memory information into essential information and sensitivity information, storing them separately with different access controls. This allows convenient access to non-sensitive data while protecting sensitive personal information from unauthorized access, resolving the contradiction between ease of operation and security.
Solution Approach 2:
The patent applies different quality attributes to different parts of the stored information by assigning sensitivity levels (first, second, third sensitivity) to different pieces of memory information. This enables differential access control where highly sensitive information requires stronger authentication while less sensitive information remains more accessible, balancing convenience and security.
2Reliability
If authentication methods are implemented for memory information, then security is improved, but access complexity increases
Solution Approach 1:
The patent implements partial authentication by requiring verification only for sensitive information (second and third sensitivity levels) while allowing direct access to non-sensitive information. This reduces authentication complexity for routine operations while maintaining strong security for critical data, resolving the contradiction between reliability and device complexity.
3Productivity
If all memory information is made accessible, then user service quality improves, but risk of information leakage increases
Solution Approach 1:
The patent assigns different sensitivity levels to different pieces of memory information, enabling selective access based on sensitivity. This allows high service quality for non-sensitive information while protecting sensitive personal information from leakage, resolving the contradiction between productivity and harmful factors.
Solution Approach 2:
The patent introduces sensitivity information as an intermediary layer between the user's access request and the actual memory information. This intermediary enables the system to evaluate access requests against sensitivity levels and authentication requirements, providing quality service while preventing information leakage.

AI summary
According to an embodiment, an electronic device comprises a communication module, a memory, and a processor configured to, upon obtaining a first utterance related to a memory service, prepare to store first information for the memory service for the first utterance and store the first information including essential information, sensitivity information for the first information, and an authentication method for the first information, detected from the first utterance, in the memory, and obtain a second utterance for looking up information related to the memory service, upon identifying that the obtained second utterance is one for looking up the first information, complete authentication based on the authentication method, and provide the essential information by a providing method determined based on the sensitivity information. Various other embodiments may be provided.
