Protected Mode Application Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parental control systems for mobile communication devices are inadequate in restricting access to specific features and applications, as they primarily focus on web content and chat activity, lacking the ability to selectively limit access to various applications and features on devices like smartphones and tablets.
Innovation Solution
Implementing a protected mode on computing devices that allows administrators to selectively enable or disable specific applications and features, requiring a passcode or pre-established task to exit, ensuring that only authorized applications and features are accessible to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional parental control applications are used to monitor and control content, then web content and chat activity can be monitored and blocked, but the ability to selectively limit access to various applications and features is insufficient
Solution Approach 1:
The system segments access control by creating separate controlled modes (protected mode, limited mode) that can independently manage access to different applications and features. Each mode can be configured with specific allowed and blocked applications, enabling fine-grained selective control rather than blanket restrictions.
Solution Approach 2:
The system implements dynamic access control where the set of available applications and features can change based on the operating mode. The administrator can dynamically configure which applications are accessible in each mode, and the system automatically enforces these changing restrictions without requiring manual intervention for each application.
2Adaptability or versatility
If a protected mode is implemented to restrict access to specific features, then selective alteration of user accessibility is enabled, but device complexity increases
Solution Approach 1:
The access control system serves multiple functions through a unified framework: it enables protected mode for children, limited mode for employees, and configurable mode for specific applications. The same underlying mechanism handles different user scenarios, reducing overall system complexity compared to separate control systems for each function.
Solution Approach 2:
The system provides self-service functionality where the administrator can configure access controls through a user-friendly interface without requiring technical expertise. The system automatically enforces the configured restrictions across all applications and features, eliminating the need for complex manual control of each individual application.
3Ease of operation
If full access is given to users to ensure ease of operation, then users can access all applications and features, but unauthorized access to inappropriate content or functions occurs
Solution Approach 1:
The system applies different access quality levels to different applications and features based on local configuration. In protected mode, certain applications are completely inaccessible, while in limited mode, specific applications have restricted access. This localized control allows ease of operation for appropriate content while blocking harmful access where needed.
Solution Approach 2:
The access control system acts as an intermediary between the user and the applications. Rather than requiring direct user access to all applications, the system mediates by filtering and controlling which applications are visible and accessible based on the configured mode, preventing unauthorized access while maintaining ease of operation for approved content.
Data Source
AI summary
An electronic device includes at least one memory unit, a plurality of applications residing on at least one of the memory units and a database residing on at least one of the memory units. The database is configured to store a record specifying a subset of the plurality of applications that are to be inaccessible to a user when in a protected mode of operation. The protected mode is designed for a user (e.g., child or friend borrowing the device) who can potentially use the device with setting that are configured under the primary user's (e.g. parent, device administrator) supervision. The device also includes a user interface through which a primary user and not other users can specify the subset of the plurality of applications to be included in the record. A processor is operatively associated with the memory unit, the database and the user interface. The processor is configured to switch, in response to a request from the primary user and not other users, between a normal mode operation in which all of the applications in the plurality of applications are available for use and the protected mode of operation.
