KDk: A Novel Machine Learning Framework for protecting Vertical Federated Learning from known Label Inference Attacks with high performance

Are you intrigued by the concept of Federated Learning (FL) and its potential to revolutionize collaborative model training? If so, this blog post is a must-read for you! In this visually captivating piece, we delve into the world of FL and explore its various data partition strategies, including Horizontal FL, Vertical FL, and Transfer Learning. Join us on this journey as we uncover the benefits, risks, and challenges associated with this cutting-edge technology.

Diving into the realm of FL, we first explore the advantages of keeping data locally and performing model updates locally. By reducing communication costs and integrating heterogeneous data, FL maintains the unique characteristics of each participant’s dataset. However, we also uncover the risks of indirect information leakage, especially during the model aggregation stage.

Next, we uncover the intricacies of different data partition strategies within FL. Horizontal FL caters to scenarios where regional branches of the same business aim to build a richer dataset, while Vertical FL involves non-competing entities with vertically partitioned data. Transfer Learning, on the other hand, addresses scenarios with diverse data distributions, offering unique challenges and advantages in the FL landscape.

As we delve deeper, we shine a spotlight on the issue of privacy leakage in FL, particularly through Label Inference Attacks. To combat this threat, researchers at the University of Pavia have developed a defense mechanism called KD𝑘 (Knowledge Discovery and k-anonymity). This innovative approach leverages Knowledge Distillation and an obfuscation algorithm to enhance privacy protection, reducing the accuracy of label inference attacks.

Finally, we explore the experimental findings that validate the efficacy of the KD𝑘 defense mechanism, showcasing a notable reduction in the accuracy of label inference attacks across various FL scenarios. Through a comprehensive comparison with existing defense strategies, the study highlights the superior performance of the proposed approach, offering a robust countermeasure against privacy threats in FL.
