Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for secure data handling in cloud environments, particularly for encrypted data, lack efficiency in protecting sensitive information from unauthorized access.
Innovation Solution
A system comprising a data gate that generates and stores virtual files based on original files, using authentication data as keys for encryption and decryption, and distributes encrypted files across multiple data storages in restricted regions, enhancing security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is secured using only authentication (user names and passwords), then ease of operation is improved, but data security deteriorates
Solution Approach 1:
The authentication system is segmented into multiple independent components: user credentials (user names and passwords), cryptographic keys, and authentication data. Each component serves a specific security function, and none alone can compromise the entire system. This segmentation allows the system to maintain ease of operation through familiar login mechanisms while achieving high security through the combined use of multiple authentication layers.
Solution Approach 2:
A data gate is introduced as an intermediary component between users and the data storage system. The data gate performs cryptographic operations, manages key distribution, and enforces access control policies. This intermediary protects sensitive data by ensuring that even if authentication credentials are compromised, the actual data remains secured through additional cryptographic layers that the data gate manages.
2Ease of operation
If encrypted files are stored in centralized location, then ease of operation is improved, but data security deteriorates
Solution Approach 1:
The storage system is segmented into multiple independent data storages distributed across different locations. Encrypted files are divided and stored across these multiple storages rather than being kept in a single centralized location. This segmentation ensures that compromising one storage does not result in complete data breach, while the system maintains ease of operation through unified access management via the data gate.
Solution Approach 2:
Different portions of encrypted files are stored in different locations with different security characteristics. The system assigns specific data segments to specific storages based on security requirements, allowing each location to have optimized security measures while maintaining overall system accessibility through the data gate's coordination.
3Reliability
If files are divided into chunks and encrypted separately, then data security is improved, but device complexity increases
Solution Approach 1:
Files are divided into smaller chunks and each chunk is encrypted separately with unique cryptographic keys. This segmentation enhances security because compromising one chunk does not expose the entire file. The data gate automates the segmentation and encryption process, managing the complexity of handling multiple encrypted chunks and their corresponding keys, thereby maintaining ease of operation despite the increased security measures.
Solution Approach 2:
The system creates multiple copies of encrypted file chunks and distributes them across different data storages. Each copy is independently encrypted, providing redundant security layers. The data gate manages these copies automatically, handling the complexity of synchronization and distribution without requiring user intervention, thus maintaining ease of operation.

AI summary
A system for secure data handling is provided. The system comprises at least one data gate (11), authentication data (15) of users accessing the at least one data gate (11), at least one original file (12) comprising content data and/or meta data, and at least one virtual file (13) comprising at least parts of the meta data. In this context, the at least one data gate (11) is configured to generate and/or store the at least one virtual file (13) on the basis of the at least one original file (12). In addition to this, the at least one data gate (11) is further configured to generate and/or store at least one encrypted file (14) on the basis of the at least one original file (12) preferably using at least parts of the authentication data (15) as key.
