Data Retention via Fingerprint-Locked Storage Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data retention methods fail to adequately protect personal data privacy, particularly in private networks, as centralized management and backup systems expose personal data to privacy risks despite security features like encryption and remote unlocking mechanisms.
Innovation Solution
A data retention method utilizing a dedicated storage module with a fingerprint-activated power source, a locking element for secure electric connections, and an encryption component for secure data exchanges between an external device and storage module, ensuring only authorized access through fingerprint authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centralized management and backup systems are used for data storage, then data management efficiency is improved, but data privacy security deteriorates
Solution Approach 1:
The system divides data storage into two separate modules: a dedicated storage module for classified information and a general storage module for other data. This segmentation ensures that sensitive data is isolated and protected through physical separation and dedicated security measures, while still allowing centralized management of the overall storage system.
Solution Approach 2:
An encryption module acts as an intermediary between the dedicated storage module and external access points. This encryption module secures the classified information through encryption/decryption operations, allowing centralized management while preventing unauthorized access to sensitive data during transmission and storage.
2Reliability
If a dedicated storage module with fingerprint authentication is used, then data security is improved, but device complexity increases
Solution Approach 1:
The fingerprint authentication function is integrated directly into the locking element of the dedicated storage module. By combining the biometric authentication mechanism with the physical locking mechanism, the system achieves enhanced security without adding separate authentication devices, thus managing complexity through functional integration.
Solution Approach 2:
The locking element automatically controls the power supply to the dedicated storage module based on fingerprint authentication results. When authentication succeeds, the locking element enables power supply; when it fails, power is cut off. This self-service mechanism eliminates the need for separate power control circuits and simplifies the overall system architecture while maintaining high security.
3Reliability
If the locking element controls power supply to the dedicated storage module, then unauthorized access is prevented, but ease of operation decreases
Solution Approach 1:
The traditional mechanical key-based locking system is replaced with a fingerprint-based biometric authentication system. This substitution eliminates the need for physical keys while providing more reliable access control through unique biometric identification, and simplifies user operation by using automatic fingerprint recognition instead of manual key insertion and turning.

AI summary
The present disclosure relates to a data retention method which ensures security of classified information in design. The data retention method comprises steps as follows: a data plug of a dedicated storage module is inserted into a data socket of an encryption module and a locking element of a lock fastener module is fixed at a locking hole on the dedicated storage module; the encryption module and the dedicated storage module are electrically connected to each other through the data socket; an external component of the encryption module is electrically connected to an external device such that classified information (saved or to be saved) is encrypted or decrypted between the external device and a storage element of the dedicated storage module by an encryption component of the encryption module during data exchanges.
