Introduction to privacy-preserving Machine Learning
Background
In privacy-preserving machine learning, the discovery of AI usage in businesses for data protection has enhanced. It has the ability for predictive analytics and history. Moreover, these algorithms predicts the security breaches that might happen and it has an initiative approach towards the cyber threats. Machine learning protects the data loss which involves human intervention. AI is useful in data preparation, operation, and automation. Moreover, machine learning helps in data analysis, fraud detection, and suspicious activities detection using ML algorithms, and potential risk identification and defend. Also, it determines abnormal activities and add an extra layer of protection and predefined signatures. This alarms online technologies.
Problem Statement
As there is an increase in large amounts of data, there are privacy and ethical concerns. So, it is difficult to maintain large sets of data and there is a chance of violations of privacy. The main challenges that are included are security issues, which mislead the data and cyber-attacks. Accordingly, the privacy risk is where personal data gets corrupted. Moreover, there are ethical issues that have discriminatory outcomes which lead to biased and incomplete data.
Objective
The main objective is to make algorithms to operate effectively towards data protection and encourage design and algorithms for data protection. Training the models that are related to different data and secure the data. To make data with more safeguarding procedures and techniques for secured information (Hong, 2024). As there is rapid evolution of AI and machine learning without compromising the privacy-preserving techniques so, it could help in ethical and privacy concerns using AI.
Literature Review
Federated Learning
Without sharing raw data, federated Learning allows multiple devices to train the models, and updates are provided to the central server. Moreover, no sharing of original data, which decreases the exposure of data risk. Keep the data on the devices locally. Despite the compromise on privacy, it applies to large-scale data (Bag, 2024). Especially, data heterogeneity is one of the challenges, which enhances the inefficiency and make the performance down.
Differential Privacy
Differential Privacy comes in the context of machine learning and statistical analysis. Creation of privacy protection and tools for the analysis of personal data and sensitive information (Nguyen, 2019). Moreover, DP gives a guarantee of privacy. The limitation is privacy. It requires strong privacy when there are heavy dataset models. Preservation of privacy is the main challenge.
Homographic encryption
Homographic encryption involves encrypted data computation. So, the encryption takes place on the results of data. It makes sure of confidentiality without exposure to data. AI-based cloud systems require encryption in the processing. During the upload of files, it enables a strong privacy guarantee.
Current challenges
There are current challenges such as privacy and performance where it maintains the accuracy of data which might lead to underperformance due to data heterogeneity. Without sacrificing the capabilities of the AI model the development of new privacy preservation techniques to give the balance between the data privacy and the performance of the model. The AI model helps in the availability of diverse data sets but there are privacy concerns that limits the availability and problems might arise due to individual data privacy protection. There are also challenges with legal compliance Federated learning and differential privacy help with legal compliance and accountability.
Methodology
Federated learning is the main measure of privacy of data it involves decentralization of data storage by participating in the learning process. Moreover, the model evaluates the data leakages and maintains model aggregation for gaining the server access. Introduction of privacy protection to prevent data leakages (A survey on federated learning: challenges and applications, 2022). The usage of differential privacy for safeguarding the information from various model outputs and adding a layer of protection to the private data. The usage of data collection to make the data which is aware of all the Federated techniques available and the training process begins with all the information such as names, records, and various addresses
The preprocessing of data will take place in which the sensitive data will be involved, and should be able to process the elimination of identifiers. There is a feature selection in which it maintains privacy. Subsequently, the development of a model architecture, which involves decision trees and neural networks, that operates the Federated phase. The model ensures updates during the stage. Moreover, the federated training provides computational updates on the local data and makes updates to the central server system (Bonawitz, Kairouz, McMahan, & Ramage, 2021).
The integration of the system with applied technologies and model updates at all levels. In the testing and evaluation based on the model created, the main objective is to further add protection of privacy measures and use the standard metrics for data sets of the training models. Ensure the privacy protection methods and maintain the ability of those techniques against privacy breaches. In addition, the evaluation of overall maintenance and computational costs. They will test scalability based on vast data sets and evaluate resource utilization during the training.
