Dual Access Management Circuit Database Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack effective management of data access between different processes, particularly in concealing confidential data and allowing flexible data usage by different software processes, leading to potential data exposure and limited customization.
Innovation Solution
The implementation of a dual access management circuit system that partitions a database into unique, shared, and extended regions, allowing controlled access by platform and application processes, ensuring data confidentiality and flexibility in data usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is shared between multiple processes, then data flexibility and accessibility are improved, but data security and confidentiality deteriorate
Solution Approach 1:
The database is segmented into multiple regions with different access control levels. Each region can be independently accessed by specific processes based on predefined permissions, allowing simultaneous data sharing for some regions while maintaining confidentiality for others.
Solution Approach 2:
An access management circuit acts as an intermediary between processes and the database. This mediator controls and monitors all access requests, granting permission only to authorized processes and blocking access to confidential data, thus enabling secure data sharing.
2Object-affected harmful factors
If data is concealed from certain processes, then data security is improved, but data customization and flexibility deteriorate
Solution Approach 1:
Different regions of the database are assigned different access control qualities. Some regions are configured to be accessible by multiple processes while others are restricted to specific processes, allowing simultaneous data confidentiality for sensitive regions and customization for application-specific regions.
3Device complexity
If a single access management system is used, then system simplicity is maintained, but the ability to manage different access rights for different processes deteriorates
Solution Approach 1:
The access management system is segmented into multiple independent access management circuits, each responsible for managing access to specific database regions. This segmentation enables flexible access control for different processes while maintaining overall system manageability through modular architecture.

AI summary
An electronic device includes a first access management circuit and a second access management circuit. The first access management circuit manages an access to a database from a first process. The second access management circuit manages an access to the database from a second process. The first access management circuit, among regions in the database, manages the access to a shared region for data to be used by both of the first process and the second process, and manages the access to a first dedicated region for data to be used by only the first process among the first process and the second process. The second access management circuit manages the access to the shared region among the regions in the database.
