Mobile Device Account Data Protection via Idle Time Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices face challenges in collectively protecting scattered account-related information, as existing technologies struggle to selectively and efficiently secure various types of data, especially when users switch devices or lose their mobile devices, leading to potential data leakage.
Innovation Solution
A mobile device with a storage location acquisition unit, access detection unit, time period determination unit, and protection unit that acquires storage locations of account-related information, detects user access, determines elapsed time, and applies protection processing when a predetermined time period has passed, ensuring collective protection of account-related information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If account-related information is stored in the mobile device for user convenience, then ease of operation is improved, but security against data leakage deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting user access and automatically determining the storage locations of account-related information before a security incident occurs. The time period determination unit pre-calculates elapsed time since last access, and the protection unit proactively applies protection processing to data based on these pre-determined conditions, preventing data leakage before it can happen.
Solution Approach 2:
The control unit acts as an intermediary between the storage locations acquisition unit and the protection unit. It receives storage location information, determines whether protection should be applied based on time period conditions, and then instructs the protection unit to apply appropriate protection processing. This intermediary function enables automated security decisions without requiring direct user intervention.
2Reliability
If protection processing is applied to all account-related information, then security is improved, but device complexity increases
Solution Approach 1:
The system segments account-related information by identifying and managing individual storage locations separately. The storage locations acquisition unit divides the data protection task into discrete units (individual storage locations), allowing the control unit to apply protection processing selectively to specific segments of data based on time period conditions, rather than treating all data uniformly.
Solution Approach 2:
The system enables self-service automation where the control unit automatically determines which data requires protection based on elapsed time since last user access. The time period determination unit self-evaluates security conditions and triggers protection processing without user intervention, reducing the operational complexity of managing data security while maintaining high reliability.
3Productivity
If automated protection processing is implemented, then security management efficiency is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system implements feedback mechanisms where the control unit continuously monitors user access patterns and elapsed time periods. The time period determination unit receives feedback about when users last accessed data and automatically adjusts protection decisions based on this feedback. This closed-loop feedback system enables efficient automated security management by continuously adapting protection levels based on actual usage patterns.
Solution Approach 2:
The system performs preliminary detection of storage locations and access patterns before security incidents occur. By pre-identifying where account-related information is stored and establishing time period baselines for each storage location, the system simplifies the measurement and detection tasks required for automated protection decisions.

AI summary
When a pre-determined time period has elapsed after a user access is last detected, a mobile device performs protection processing on account-related information. The mobile device includes an access detection unit that detects that a user accesses the mobile device, and a time period determination unit that determines whether or not a pre-determined time period has elapsed from a last user access time point at which the user last accessed the mobile device. The mobile device further includes a storage location acquisition unit that acquires a location in the data storage unit in which the account-related information is stored, and a protection unit that performs the protection processing on the account-related information based on the storage location of the account-related information acquired by the storage location acquisition unit, when the time period determination unit determines that a pre-determined time period has elapsed from the last user access time point.
