Innovation Solution

A dispersed storage network (DSN) utilizing computing devices with dispersed storage error encoding and decoding capabilities, managed by a managing unit and integrity processing unit, ensures data resilience through error encoding and decoding, secure storage, and efficient data management, including vault creation and billing, while maintaining data integrity and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is stored in a distributed manner across multiple cloud computing resources, then productivity and response time are improved, but data integrity and security become more difficult to maintain

Engineering Contradiction:

Improveresponse timeVSAvoiddata integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments data into multiple data slices that are distributed across different storage units in the cloud computing environment. Each slice is independently stored, allowing parallel access and improved response time while maintaining data integrity through the segmentation structure itself.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates multiple copies of data slices and distributes them across different storage units. This copying approach enables redundant storage without requiring complete duplicate copies, improving both response time through parallel access and data integrity through distributed redundancy.

Inventive Principle:

Principle #26Copying

2Reliability

If redundant copies of data are stored for fault tolerance, then reliability is improved, but storage space utilization deteriorates

Engineering Contradiction:

Improvefault toleranceVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #26Copying

3Reliability

If data is encrypted for security, then data security is improved, but processing speed deteriorates

Engineering Contradiction:

Improvedata securityVSAvoidprocessing speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent performs encryption operations during the data upload phase before distribution to cloud storage units. By completing the encryption action preliminarily, the stored data remains secure while retrieval operations can proceed more efficiently without repeated encryption/decryption cycles during processing.

Inventive Principle:

Principle #10Preliminary action
