Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual device backup is performed for each IoT device, then data security is maintained, but system complexity and processing overhead increase significantly
Solution Approach 1:
The patent combines backup operations for multiple IoT devices into a single centralized backup process. The backup agent aggregates data from multiple devices and performs one backup operation that covers all devices, eliminating the need for individual backup operations for each device while maintaining data security through centralized management and verification.
Solution Approach 2:
The backup agent is designed as a universal component that can handle backup operations for multiple different IoT devices simultaneously. It implements a standardized interface that works across diverse device types, allowing a single backup mechanism to serve multiple functions and devices without requiring device-specific backup implementations.
2Productivity
If centralized data management is implemented for all IoT devices, then backup efficiency is improved, but data transmission and processing load increase
Solution Approach 1:
The patent extracts only the necessary identification and verification information (device identifiers, data characteristics) from each IoT device and transmits this minimal metadata to the management server, rather than transmitting all actual data. This reduces the data transmission load significantly while still enabling centralized coordination of backup operations.
Solution Approach 2:
The backup agent serves as an intermediary between IoT devices and the management server, performing local data aggregation and preprocessing. It consolidates data from multiple devices into a unified format before transmission, reducing the overall data load on the network and server while maintaining centralized management capabilities.
3Reliability
If signature verification is performed for each data packet, then data authenticity is ensured, but processing time and computational overhead increase
Solution Approach 1:
The patent combines multiple signature verifications into a single batch verification process. Instead of verifying signatures for each individual data packet separately, the system aggregates multiple signatures and verifies them collectively, significantly reducing the total verification time and computational overhead while maintaining the authenticity guarantee for all data packets.
4Adaptability or versatility
If multiple IoT devices are registered with unique identifiers, then device individuality is maintained, but registration and management complexity increases
Solution Approach 1:
The patent implements a universal registration mechanism that handles multiple IoT devices through a standardized process. The management server uses a unified interface and data structure to register and manage diverse devices, maintaining their individual identities through unique identifiers while simplifying the registration process through consistent procedures applicable to all device types.

AI summary
A method, a device, and a program product for backing up data in the Internet of Things (IoT) is disclosed. An IoT system includes an IoT manager and a plurality of IoT devices. In response to receiving a registration request for registering an IoT device among a plurality of IoT devices with an IoT manager, a signature public key is received from the IoT device. Atomic data associated with the IoT device is received that includes a signature generated by using a signature private key corresponding to the signature public key. The signature is verified based on the signature public key. In response to the signature being successfully verified, a backup data package for backup is generated based on the atomic data. Accordingly, data may be backed up in the IoT with higher performance, thereby improving the security and reliability of the entire IoT.
