This project aims to identify a sustainable way to construct and train machine learning models. A crucial factor in creating effective machine learning models lies in having access to vast amounts of data. However, this can pose a challenge due to the confidentiality and dispersion of data across various entities. Collecting all the data can thus become a security concern, as transmitting it to a centralized computing location may expose the data to security risks. One solution to this issue is federated learning, which utilizes locally trained AI models. Instead of transmitting data to a centralized computing location, this approach entails sending locally trained AI models and combining them into a global model. In recent years, a method called Model Inversion Attacks has emerged, revealing their potential risk in the context of extracting training data from trained AI models. This methodology potentially heightens the vulnerability of sending models instead of data, posing a security risk. In this project, various Model Inversion Attack methodologies will be examined to further understand the risk of sending models instead of data. The papers examined showed some results of extracting data from trained AI models, although they do not raise significant concerns. Nonetheless, future research in MIA may create security concerns when sending models between parties. Sending parts of the locally trained models to the global model effectively neutralizes the effectiveness of all the examined Model Inversion Attack studies. However, from the results presented in this project, it is evident that challenges persist when only sending parts of a trained model. The challenge was to construct a usable federated learning model while only sending parts of a trained model. To achieve a good federated learning model, several adjustments had to be made to the algorithm, which showed some promising results for the future of federated learning.
