Mobile Security Interface Segmentation for Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device security interfaces do not effectively display relevant information or indicate new updates when in a secure screen saver state, failing to provide users with timely access to both secure and non-secure data without compromising security.
Innovation Solution
A mobile device security interface that operates in three states: a controlled access state where only non-secure data is accessible, a verification state where users must input security information to access secure data, and a full access state granting access after successful authentication, with the ability to indicate changes in secure data without authentication and automatically update non-secure data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security screen saver is activated after a period of inactivity, then security is improved by restricting access to secure data, but the ability to display relevant information and indicate updates is lost
Solution Approach 1:
The security interface segments data into secure and non-secure categories, allowing differential access control. Non-secure data is displayed on the screen saver while secure data access is restricted, resolving the contradiction by providing information display capability for non-critical data while maintaining security for sensitive data
Solution Approach 2:
The screen saver acts as an intermediary layer between the user and the device data. It provides a controlled interface that displays non-secure information and indicates secure data updates without requiring full authentication, thus maintaining both security and information accessibility
2Loss of information
If static information is displayed on the security screen saver, then information display is provided, but the ability to indicate new or updated information is lost
Solution Approach 1:
The screen saver implements feedback mechanisms by displaying indicators when secure data updates are received. The system monitors for changes in secure data and provides visual feedback to the user without requiring authentication, thus maintaining both information display and update indication capabilities
Solution Approach 2:
The screen saver transitions from a static display to a dynamic interface that can indicate updates. By incorporating update indicators and maintaining the ability to respond to data changes, the screen saver becomes dynamic while still providing information display functionality
3Ease of operation
If access to non-secure data is permitted without authentication, then ease of operation is improved, but security control is weakened
Solution Approach 1:
Different security levels are applied to different data types. Non-secure data is made easily accessible without authentication, while secure data maintains strict access control. This local differentiation of security quality allows ease of operation for non-critical data while preserving security control for sensitive data
Data Source
AI summary
A method and device are described which provide a security interface, preferably for a mobile device. The security interface provides user-selectable non-secure data that is displayed without the need for a password. The non-secure data is preferably updated on a regular basis, and can be obtained from different sources, as selected by a user. The secure data can be accessed after successful authentication, such as a positive password verification. Additional non-secure data, related to the displayed non-secure data, can preferably be accessed, with or without a need for a password. An indication can be provided to inform a user that secure data has been updated, without the need to access such secure data. The security interface is preferably enabled after a predetermined timeout period. The interface allows the device to operate in three data access states: a controlled access state; a verification state; and a full access state.
