Secure Data Access Context Management for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face inefficiencies and user experience disruptions due to the need for frequent user authorization for accessing and exporting private data, especially when multiple accesses or data exports are performed as part of a single process.
Innovation Solution
The technology allows on-device access and processing of restricted data without initial user authorization, while maintaining security by preventing data exportation without prior user approval, thereby reducing the frequency of user prompts and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authorization is required for every data access and export operation, then data security is maintained, but user experience is disrupted and computational efficiency decreases
Solution Approach 1:
The system performs preliminary actions by establishing user authorization and computational context before data access operations occur. When a user authenticates and provides authorization, the system records this contextual information and uses it to enable subsequent data access operations without requiring repeated authorization prompts, thereby maintaining security while improving user experience
Solution Approach 2:
The system implements feedback mechanisms where computational context and authorization status are continuously monitored and fed back into the access control decisions. This allows the system to adapt its authorization requirements based on the current computational state and user interactions, reducing unnecessary prompts while maintaining security
2Reliability
If frequent user authorization prompts are displayed, then data access security is ensured, but computational resources are wasted and processing time increases
Solution Approach 1:
The system performs preliminary evaluation of authorization context and computational state before each data access operation. By pre-determining whether authorization is already established or computational context validates the access request, the system avoids unnecessary authorization prompts and security checks, thereby improving computational efficiency while maintaining security
Solution Approach 2:
The system applies partial action by providing authorization and security checks only when necessary based on the current computational context. Instead of requiring full authorization verification for every operation, the system uses contextual information to determine when simplified access control is appropriate, reducing computational overhead while maintaining adequate security
3Reliability
If user authorization is required for multiple data accesses in sequence, then data protection is maintained, but the overall process becomes inefficient and disruptive
Solution Approach 1:
The system merges multiple data access operations into a single authorized computational context. When a user provides initial authorization and the system establishes the appropriate computational context, subsequent data access operations within the same process or session are performed without requiring repeated authorization prompts, thereby reducing total processing time while maintaining data protection
Solution Approach 2:
The system maintains continuity of useful action by preserving authorization context and computational state across multiple sequential operations. This allows the system to continue data access operations smoothly without interruption for re-authorization, reducing the time loss associated with multiple discrete authorization prompts while ensuring ongoing data protection

AI summary
The subject disclosure provides systems and methods for providing secure data access for electronic devices. The secure data access can allow processes, such as scripts, at a device to be executed to obtain and process restricted data locally on the device without requesting user authorization for the access and processing. The secure data access can prevent the processes from exporting the data, and/or data derived from the data, from an execution space of the processes, whether locally on the device or externally from the device, without obtaining user authorization for the exportation. In this way, user authorizations can be obtained for securing restricted data, in a way that is efficient for the device, for the processes accessing and processing the data, and for the user.
