Wavefront Multiplexing Digital Enveloping for Cloud Data Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud storage and transport methods lack effective privacy protection and reliability, particularly in securing sensitive data, as they often rely on server-side encryption and do not adequately address concerns about data integrity and ownership.
Innovation Solution
The implementation of Wavefront multiplexing (WF muxing) techniques for enveloping and de-enveloping digital data, which transforms multiple data sets into multiplexed data sets that appear as a weighted sum of the original data, ensuring enhanced privacy and redundancy, and can be used for secure data transport and storage by utilizing known digital files as envelopes that preserve human sensor-compatible appearances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If server-side encryption is used for cloud storage, then data security is improved, but data integrity and ownership concerns remain unresolved
Solution Approach 1:
The patent segments data into multiple data sets that are transformed through WF muxing into multiplexed data sets. Each data set is processed independently and then combined, allowing for distributed storage and retrieval while maintaining integrity through the mathematical transformation relationship between original and multiplexed data.
Solution Approach 2:
The patent introduces WF muxing transformation as an intermediary process between the original data and its cloud storage representation. This transformation layer (creating multiplexed data sets that appear as weighted sums) serves as a mediator that protects data while enabling verification of integrity without exposing the original information.
2Reliability
If multiple data sets are transformed into multiplexed data sets through WF muxing, then privacy protection is enhanced, but data access complexity increases
Solution Approach 1:
The patent applies parameter changes by transforming data sets through WF muxing with specific weighting coefficients. The transformation parameters (weights in the weighted sum) are designed to preserve the appearance characteristics while enabling recovery through inverse transformation, thus enhancing privacy without permanently altering the data's fundamental structure.
Solution Approach 2:
The patent employs inversion by creating a reversible transformation process. The WF muxing transformation that obscures data can be inverted through de-enveloping operations to recover the original data sets, allowing authorized receivers to access embedded data while maintaining privacy during storage and transmission.
3Reliability
If digital enveloping is used for secure data transport, then data confidentiality is improved, but transmission overhead increases
Solution Approach 1:
The patent merges multiple data sets into a single multiplexed data set through WF muxing transformation. By combining several data sets that appear as a weighted sum in the multiplexed form, the system reduces the number of separate transmissions needed while maintaining confidentiality through the transformation relationship.
Solution Approach 2:
The patent creates multiplexed data sets that serve multiple functions simultaneously: they provide confidential data transport, maintain data integrity through the transformation relationship, and enable redundancy. The same multiplexed data structure supports both security and verification purposes without requiring separate mechanisms.
Data Source
AI summary
Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. A customized set of WF muxing on multiple digital files as inputs including at least a data message file and a selected digital envelop file, is configured to guarantee at least one of the multiple outputs comprising a weighted sum of all inputs with an appearance to human natural sensors substantially identical to the appearance of the selected digital envelop in a same image, video or audio format. The output file is the file with enveloped or embedded messages. The embedded message may be reconstituted by a corresponding WF demuxing processor at destination with the known a priori information of the original digital envelope.
