Solution Overview
Problem
Existing computer storage systems face issues with memory device failures, particularly in commercial-grade devices using physical movement, leading to data loss and security concerns, and redundant array of independent discs (RAID) solutions increase maintenance and unauthorized access risks while reducing storage capacity.
Innovation Solution
A distributed storage network (DSN) system that utilizes error coding dispersal to partition and distribute data across geographically diverse locations, ensuring data integrity and security through forward error correction and redundant storage, managed by a DS managing unit and processed by a DS processing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RAID solutions are used to protect against memory device failures, then data reliability is improved, but storage capacity is reduced and maintenance complexity increases
Solution Approach 1:
The patent segments data into multiple data slices and distributes them across multiple storage devices. Error correction codes are also segmented and distributed with the data slices. This segmentation allows the system to achieve redundancy and reliability without requiring complex RAID configurations, as each slice can be independently stored and retrieved.
Solution Approach 2:
The patent introduces error correction codes as an intermediary between the data and storage devices. These codes act as a mediator that enables reliable data recovery without requiring complex RAID management. The error correction codes are distributed alongside data slices and can be used to reconstruct lost or corrupted data without needing redundant array configurations.
2Reliability
If RAID solutions are implemented to prevent data loss, then data security is improved, but unauthorized access risk increases
Solution Approach 1:
The patent divides data into multiple encrypted slices that are distributed across different storage devices. Each slice alone is insufficient to reconstruct the original data, providing inherent security against unauthorized access. This segmentation approach maintains data security while reducing the risk associated with centralized RAID configurations.
Solution Approach 2:
The patent applies different properties to different parts of the stored data. Each data slice and error correction code is locally optimized and distributed across different locations. This local quality approach ensures that even if one storage device is compromised, the distributed nature of the slices prevents unauthorized access to the complete data set.
3Quantity of substance
If commercial-grade memory devices with physical movement are used, then storage capacity is improved, but data loss risk increases
Solution Approach 1:
The patent applies error correction codes to data slices before storing them on commercial-grade memory devices. This preliminary action prepares the data for potential failures by pre-calculating and distributing the necessary correction information. When data loss occurs, the preliminary error correction codes enable reliable data recovery without requiring redundant storage configurations.
Solution Approach 2:
The patent introduces error correction codes as an intermediary layer between the data and commercial-grade storage devices. This intermediary protects the data from physical movement-related failures while allowing the use of high-capacity commercial devices. The error correction codes mediate between the physical storage medium and the logical data, preventing data loss despite the inherent risks of physical movement in commercial devices.

AI summary
A method for data transmission includes receiving a first data stream for transmission to a mobile device, segmenting the first data stream to produce a first plurality of data segments and receiving a second data stream, where the second data stream including location information for the mobile device. The method continues by segmenting the second data stream to produce a second plurality of data segments, dividing a data segment of the first plurality of data segments into a first plurality of data blocks and then dividing a data segment of the second plurality of data segments into a second plurality of data blocks, where the data segment of the first plurality of data segments is time aligned with the data segment of the second plurality of data segments. A data matrix is then created from the first and second plurality of data blocks and then based on the data matrix transmitting a first data block from each of the first and second plurality of data blocks to a first relay unit. Finally, based on the data matrix a second data block from each of the first and second plurality of data blocks is transmitted to a second relay unit.
