Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cloud computing technologies fail to adequately protect privacy-sensitive data during transmission and processing, particularly in healthcare, due to the risk of hacking and data breaches.

Innovation Solution

Scrambling data at the client system before transmission to the cloud, ensuring that only scrambled data is processed and stored, and descrambling is performed on the client side, using pseudorandom location mapping or mathematical functions to maintain data privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted and stored in cloud computing systems, then processing capacity and scalability are improved, but data privacy and security are worsened due to hacking risks

Engineering Contradiction:

Improveprocessing capacityVSAvoiddata security risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs scrambling of data before transmission to the cloud computing system. This preliminary action ensures that data is encrypted in advance, so even if the cloud system is compromised, the stolen data remains unintelligible without the scrambling key that remains on the client device.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention extracts the critical security function (data scrambling/encryption) from the cloud computing system and places it exclusively on the client device. The cloud system only receives and processes scrambled data, never accessing unscrambled data, thus removing the security vulnerability from the cloud infrastructure.

Inventive Principle:

Principle #2Taking out (Extraction)

2Object-affected harmful factors

If data is scrambled before transmission to maintain privacy, then data security is improved, but processing capability is worsened due to computational overhead

Engineering Contradiction:

Improvedata securityVSAvoidprocessing capability

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The cloud computing system processes copies of the scrambled data rather than the original unscrambled data. This allows the system to perform computations on encrypted data directly, avoiding the need to decrypt, process, and re-encrypt, thus minimizing the impact on processing capability while maintaining security.

Inventive Principle:

Principle #26Copying

3Ease of operation

If unscrambled data is stored in the cloud system, then data accessibility is improved, but privacy protection is worsened due to potential breaches

Engineering Contradiction:

Improvedata accessibilityVSAvoidprivacy protection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Data is scrambled before being stored in the cloud system, ensuring that even if data is accessed or stolen, it remains in an unintelligible state. The scrambling key never leaves the client device, providing preliminary protection against privacy breaches while maintaining data accessibility for authorized processing.

Inventive Principle:

Principle #10Preliminary action

AI summary

Methods and systems for protecting digital client data transmitted to a computing cloud (200) for data processing ensure privacy of the client data by transmitting only scrambled client data to the computing cloud and never storing descrambled client data in the computing cloud. To the extent that descrambling is necessary for processing the client data with the computing cloud, descrambling is embedded in the processing so that descrambled client data is never output or stored by the computing cloud.
