Privacy Vulnerabilities in Multi-Cloud Machine Learning: Five Integrated Theoretical Frameworks for Systematic Understanding, Assessment, and Mitigation

Puntos clave

This research aims to develop frameworks for understanding and mitigating privacy vulnerabilities in multi-cloud machine learning.
Analysis of 27 privacy incidents across major cloud providers like AWS and Azure.
Development of five frameworks including a vulnerability model and protection mechanism interaction framework.
Testing models for classification accuracy and risk assessment.
The Three-Dimensional Vulnerability Model achieved 87% classification accuracy.
The Deployment-Risk Taxonomy covered 92.6% of documented incidents in privacy.
Frameworks provide practitioners actionable guidance for privacy-preserving machine learning.

Resumen

This paper presents five integrated theoretical frameworks for understanding, assessing, and mitigating privacy vulnerabilities in multi-cloud machine learning environments. Drawing on analysis of 27 documented privacy incidents across major cloud providers (AWS: 40.7%, Azure: 33.3%, Google Cloud: 25.9%), we develop: (1) a Three-Dimensional Vulnerability Model achieving 87% classification accuracy; (2) a Protection Mechanism Interaction Framework identifying synergistic and interfering combinations; (3) a Deployment-Risk Taxonomy covering 92.6% of documented incidents; (4) a Protection Selection Model with validated decision utility function; and (5) a comprehensive Evaluation Metrics Framework. All validation criteria were exceeded, providing practitioners with actionable guidance for privacy-preserving machine learning deployments in multi-cloud environments.
