Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately identifying and securely erasing data from storage devices in a large number of electronic apparatuses without errors, which is time-consuming and inefficient.
Innovation Solution
An electronic apparatus equipped with a processor that communicates with a server device to register and manage storage devices, ensuring data erasure only when identification information matches, using a secure erase command and verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data erasure is performed in storage devices of a large number of electronic apparatuses, then data erasure can be completed, but it takes time and effort and increases the risk of erroneous erasure
Solution Approach 1:
A server device is introduced as an intermediary between the electronic apparatus and the storage device. The server manages the erasure process by receiving erasure requests, verifying identification information, and controlling the erasure operation. This intermediary system ensures accurate targeting of storage devices while automating the process to reduce time and human error.
Solution Approach 2:
The system implements feedback mechanisms where the electronic apparatus transmits identification information of the storage device to the server, and the server responds with verification results and erasure commands. After erasure, the system provides feedback on the erasure result, enabling confirmation that the correct device was erased and the operation was successful.
2Productivity
If automated erasure process is implemented, then time and effort are reduced, but the risk of erroneously erasing data from non-target devices increases
Solution Approach 1:
Before the erasure operation is executed, the system performs preliminary actions including transmitting identification information of the storage device to the server, verifying that the identification matches the target, and obtaining erasure permission. This preliminary verification ensures that only the intended storage device is erased, preventing erroneous erasure of non-target devices.
Solution Approach 2:
The automated system incorporates feedback loops where the server receives identification information from the electronic apparatus, verifies it against the target storage device, and only issues erasure commands when verification succeeds. This feedback mechanism maintains high accuracy in target identification while enabling automated execution.
3Reliability
If identification verification is performed before erasure, then erroneous erasure is prevented, but the process becomes more complex
Solution Approach 1:
The server device performs multiple functions within a single system: it receives erasure requests, verifies identification information, manages erasure permissions, and controls the erasure process. By consolidating these functions in a universal server system, the verification process is integrated smoothly without requiring separate complex verification hardware or procedures.
Solution Approach 2:
The server acts as an intermediary that handles the verification complexity centrally. Instead of implementing complex verification logic in each electronic apparatus or storage device, the server manages all verification operations, simplifying the overall system architecture while ensuring accurate target identification.

AI summary
An electronic apparatus includes a first storage device and a processor. The processor causes a server device to register the electronic apparatus by transmitting a first signal including identification information for identifying the first storage device, transmits, to the server device, a second signal including identification information of the first storage device and inquiring whether or not it is registered in the server device that data stored in the first storage device is to be erased, and erases the data stored in the first storage device when the electronic apparatus receives a third signal instructing erasure of the data stored in the first storage device. The third signal is transmitted when the identification information of the first storage device matches the identification information of the first storage device and it is registered in the server device that the data stored in the first storage device is to be erased.
