Wavefront Multiplexing for Cloud Data Enveloping and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud storage and transport methods lack adequate privacy protection, relying on server honesty for encrypted files and raising concerns about data integrity and ownership, particularly in cases of data breaches like the iCloud hacking incident, where celebrity images were leaked.
Innovation Solution
Wavefront multiplexing (WF muxing) techniques are used to create multiplexed data sets that are unintelligible on their own, allowing for enhanced privacy and redundancy through digital enveloping and de-enveloping processes, where data is transformed into a form that appears identical to a selected digital envelope, ensuring only authorized receivers can access the original information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption is used on server side, then data security is improved, but client must rely on server operator honesty which reduces system reliability
Solution Approach 1:
The patent introduces a third-party verification mechanism where clients can verify data integrity and authenticity through cryptographic proofs without relying solely on server honesty. The system enables clients to independently verify that stored data matches what was uploaded and that the server has not tampered with the data, thereby resolving the trust issue while maintaining security.
Solution Approach 2:
The system implements feedback mechanisms where clients receive verification information about their stored data. This allows clients to confirm data integrity and authenticity, creating a feedback loop that ensures reliability without requiring continuous trust in the server operator's honesty.
2Reliability
If data is encrypted on server side, then data protection is improved, but data integrity monitoring becomes difficult without scrutinizing stored data
Solution Approach 1:
The patent replaces direct mechanical inspection of stored data with cryptographic verification mechanisms. Instead of needing to scrutinize the actual stored data to monitor integrity, the system uses cryptographic hashes, digital signatures, and verification tokens that can be independently checked without accessing or altering the encrypted data itself.
Solution Approach 2:
Cryptographic verification mechanisms act as intermediaries between the client and the stored data. These mechanisms provide integrity information without requiring direct interaction with the encrypted data, allowing clients to monitor data integrity while the data remains protected and inaccessible.
3Reliability
If WF muxing techniques are used for data enveloping, then privacy protection and redundancy are improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing into distinct stages: data preparation on the client side, transmission through the cloud, and verification on the client side. The WF muxing operation is performed only when needed, and the complexity is managed by breaking down the overall process into manageable segments that can be executed independently.
Solution Approach 2:
The system applies WF muxing selectively rather than universally. The multiplexing operation is performed only for data that requires enhanced privacy protection and redundancy, allowing the system to achieve security benefits while minimizing processing complexity for data that does not require these additional protections.

AI summary
Data files with digital envelops may be used for many new applications for cloud computing. The new applications include games and entertainments such as digital fortune cookies, and treasure hunting, unique techniques for digital right management, or even additional privacy and survivability on data storage and transport on cloud computing. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. 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. Enveloping processing is a subset of WF muxing processing. 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. In short, digital enveloping/de-enveloping can be implemented via WF muxing and demuxing formulations. WF muxed data featured enhanced privacy and redundancy in data transport and storage on cloud. On the other hand, data enveloping is an application in an opposite direction for conventional WF muxing applications as far as redundancy is concerned. Enveloped data are intended only for limited receivers who has access to associated digital envelope data files with enhanced privacy for no or minimized redundancy.
