Biometric Backup Trigger for Mobile Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information stored in electronic devices is not backed up when the device is lost or stolen, leading to incomplete data recovery as new contacts or data added during backup intervals are deleted.
Innovation Solution
An information processing method and electronic device that uses biometric feature acquisition units to determine if an unauthorized user is attempting to access the device, triggering automatic backup of critical data to a secondary device when the biometric features do not match the preset owner's information, ensuring complete data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup is performed only at fixed intervals or upon user initiation, then the backup operation is simple and energy-efficient, but new data added between backups is lost when the device is stolen or lost
Solution Approach 1:
The system performs preliminary actions by continuously monitoring data changes in the background and automatically triggering backup operations when new data is detected, rather than waiting for fixed intervals or user initiation. This ensures data is backed up before the device is potentially stolen or lost.
Solution Approach 2:
The system establishes a feedback mechanism where the backup module continuously monitors for data changes, and when changes are detected, it automatically initiates a backup operation. This closed-loop feedback ensures that any new data added to the device is promptly backed up without requiring user intervention.
2Reliability
If continuous monitoring for data changes is implemented, then data backup completeness is improved, but energy consumption and processing overhead increase
Solution Approach 1:
Instead of truly continuous monitoring, the system employs periodic sampling to detect data changes. The backup module checks for new data at regular intervals or triggers based on specific events (such as adding new contacts), balancing the need for data completeness with energy conservation by not maintaining constant active monitoring.
3Reliability
If automatic backup triggering based on biometric recognition is used, then data loss is prevented, but the system requires additional hardware and processing resources
Solution Approach 1:
The system implements self-service functionality where the backup module autonomously monitors data changes, determines when backup is needed, and executes the backup operation without requiring user initiation or complex external intervention. The system serves itself by automatically managing its own data protection needs.
Solution Approach 2:
The biometric recognition system serves multiple functions: it not only authenticates users but also triggers backup operations when unauthorized access is detected. This multi-functionality reduces the need for separate dedicated backup triggering mechanisms, thereby managing system complexity more efficiently.

AI summary
An information processing method and electronic device are provided. The electronic device includes a biometric feature acquisition unit and a display unit. The method includes: determining whether an unlock operation is received in when the electronic device is in a lock-screen state, to obtain a first determination result; obtaining first biometric feature information of a user with the biometric feature acquisition unit during a process for performing the unlock operation when the first determination result indicates that the unlock operation is received; determining whether the first biometric feature information matches preset feature information to obtain a second determination result; generating a first backup instruction for backing-up first data in the electronic device when the second determination result indicates that the first biometric feature information does not match the preset feature information; and executing the first backup instruction to backup the first data into a second electronic device.
