Data Encryption Segmentation Rolling Lock Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data encryption technologies face challenges in allowing access to data during the encryption process, leading to limited access and potential incomplete encryption due to restricted read/write capabilities, which can result in downtime and ensure that all intended data is encrypted.
Innovation Solution
Implementing a method that locks specific data segments during encryption, allowing partial access to other segments, and using a 'rolling lock' approach to ensure all data is encrypted without denying access entirely, while maintaining a list to track encryption status and re-encrypting as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access to data is limited or suspended during encryption process, then encryption security is improved, but data availability and productivity deteriorate
Solution Approach 1:
The patent divides the data storage device into multiple data segments and encrypts them individually rather than locking the entire device. This segmentation allows the encryption process to proceed on specific segments while other segments remain accessible, resolving the contradiction between security and availability by applying encryption controls at a granular level.
Solution Approach 2:
The patent implements dynamic access control where the ability to read and write data changes over time during the encryption process. Different data segments are locked and unlocked at different times based on the encryption progress, allowing the system to adapt between security requirements and data availability needs throughout the encryption lifecycle.
2Productivity
If access to data is provided during encryption process, then data availability is improved, but encryption completeness and reliability deteriorate
Solution Approach 1:
By segmenting data into multiple portions and encrypting them sequentially or in parallel batches, the system can maintain encryption integrity for each segment while allowing access to other segments. This ensures that encryption completeness is maintained for accessed data while overall data availability is preserved through partial access to non-encrypted segments.
Solution Approach 2:
The patent employs a list data structure to track the encryption status of each data segment. This feedback mechanism monitors which segments have been encrypted and which remain accessible, allowing the system to make informed decisions about access control and encryption progress, ensuring that encryption completeness is maintained while managing data availability.
3Reliability
If entire data storage device is locked for encryption, then encryption security is improved, but downtime and loss of time increase
Solution Approach 1:
The patent applies segmentation by dividing the data storage device into multiple encryptable data segments and processing them individually. This allows the encryption operation to proceed incrementally across segments rather than requiring a complete device lock, significantly reducing the total downtime while maintaining security through systematic encryption of each segment.
Solution Approach 2:
The patent prepares for encryption by creating a list of data segments to be encrypted before the actual encryption process begins. This preliminary organization allows for efficient planning and execution of the encryption process, minimizing disruption time by pre-identifying which segments need to be locked and for how long, thereby reducing overall downtime.
