IoT Data Erasure Prevention With Synchronized Protection Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT terminals mistakenly deleting local data due to misoperations or server anomalies lead to connectivity issues, reducing the reliability of IoT systems.
Innovation Solution
Implementing misdeletion prevention switches on both IoT terminals and user terminals, ensuring these switches are synchronized to prevent deletion requests from being acted upon when active, thereby maintaining data integrity and system reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the IoT terminal clears local data when a deletion request is triggered, then the deletion function works as intended, but the IoT terminal cannot connect to the server and system reliability decreases
Solution Approach 1:
The patent applies preliminary action by setting a misdeletion prevention switch before any deletion operation can occur. When this switch is enabled, it proactively blocks deletion requests from being processed by the IoT terminal, server, or user terminal, preventing the harmful effect before it can manifest. This allows the deletion function to remain available when needed while providing automatic protection against erroneous deletions.
2Reliability
If a misdeletion prevention switch is added to the IoT terminal and user terminal, then data misdeletion is prevented and system reliability improves, but device complexity increases
Solution Approach 1:
The misdeletion prevention switch serves multiple functions: it blocks deletion requests at the IoT terminal, prevents the server from processing deletion requests, and stops the user terminal from initiating deletions. This single control mechanism provides universal protection across the entire system architecture, achieving comprehensive data protection without requiring multiple separate protective measures.
Solution Approach 2:
The misdeletion prevention switch acts as an intermediary control element that mediates between the user's deletion intent and the actual deletion execution. When enabled, it intercepts deletion requests before they can cause harm, allowing the system to maintain both the deletion functionality and data protection without direct conflict between these opposing requirements.
3Reliability
If the misdeletion prevention switch is synchronized across user terminal and IoT terminal, then consistent protection is achieved, but communication overhead and system complexity increase
Solution Approach 1:
The system implements feedback by having the IoT terminal report the status of its misdeletion prevention switch to the server, which then synchronizes this status to the user terminal. This feedback mechanism ensures that both terminals have consistent information about the protection state, allowing them to coordinate their deletion blocking behavior without requiring complex continuous communication protocols.

AI summary
This application is applicable to the field of communications technologies, and provides a method and a device for preventing data misdeletion, a storage medium, and a program product. The method includes: Each of an IoT terminal and a user terminal is provided with a misdeletion prevention switch; and when a user opens the misdeletion prevention switch of the user terminal, the misdeletion prevention switch of the IoT terminal is synchronously opened, and when a server obtains a deletion request generated by the server, the server does not respond to the deletion request. In this way, the misdeletion prevention switch of the IoT terminal is in an opened state, data of the IoT terminal stored in the server is not deleted, and data of the IoT terminal stored in the IoT terminal is also not deleted, so that related data of the IoT terminal can be prevented from being mistakenly deleted, to prevent the IoT terminal from being mistakenly deleted from an Internet of Things that the IoT terminal has accessed. This can improve reliability of an IoT system.
