Encrypted Tag Data Transfer for Secure Storage Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers may be hesitant to transmit inspection information, such as log data, for malfunctioning storage devices due to security concerns, leading to delays in diagnosing issues as service engineers need to physically visit and handle sensitive information.
Innovation Solution
A data transfer control system that generates and transmits encrypted tag information and scrambles inspection data using a hash-based mask pattern, ensuring secure transmission and analysis without exposing confidential information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inspection information is transmitted via network with authentication and encryption, then information security is improved, but transmission may not occur due to customer security concerns
Solution Approach 1:
The patent extracts only the necessary inspection information (log data, status information) from the storage device and transmits it to the service provider's server, rather than requiring physical device transfer. This extraction approach maintains security while enabling efficient remote diagnosis.
Solution Approach 2:
The patent introduces an automated data transmission system as an intermediary between the storage device and service provider. The system uses pre-shared keys and encrypted channels to automatically transmit inspection information, eliminating the need for physical device handling while maintaining security.
2Reliability
If service engineer visits customer to acquire inspection information, then information security is maintained, but time for malfunction inspection increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring security credentials (shared keys, authentication mechanisms) in the storage device before malfunction occurs. When a malfunction happens, the device can immediately and securely transmit inspection information without requiring physical engineer intervention, thus reducing inspection time while maintaining security.
Solution Approach 2:
The storage device performs self-service by automatically generating and transmitting its own inspection information (log data, status information) to the service provider's server using pre-configured security credentials. This eliminates the need for physical engineer visits while maintaining information security through automated encrypted transmission.
3Reliability
If service engineer handles confidential information physically, then information security is maintained, but complexity of service process increases
Solution Approach 1:
The patent replaces the mechanical process of physical device handling and manual information extraction with an automated electronic data transmission system. The system uses cryptographic protocols and network communication to securely transmit inspection information, simplifying the service process while maintaining or improving security compared to physical handling.
Data Source
AI summary
According to an embodiment, a data transfer control device includes a controller, and the controller generates tag information when the controller receives a tag generation request, and encrypts the tag information, transmits the encrypted tag information to a device that transmits the tag generation request, processes data stored at a predetermined address to generate data for transmission when an address at which the data related to the data transfer request is stored includes the predetermined address, scrambles or encrypts the data for transmission using the tag information, and transmits the scrambled or encrypted data to the device.
