Ensuring Data Confidentiality through an In-Depth Analysis of Advanced Privacy-Preserving Methodologies in Data Science
Year: 2025
Type: article
Abstract: Privacy-preserving methods are of the greatest significance in the field of information technology as they guarantee ethical and secure data usage. The current review presents an in-depth review of state-of-the-art privacy-preserving methods such as differential privacy, Secure Multi-Party Computation (SMPC), homomorphic encryption, federated learning, and anonymization techniques. The paper presents the theoretical backgrounds, practical applications, limitations, and future advancements of the above methods, focusing on recent developments. After briefly introducing data science's privacy risk, the review presents anonymization techniques such as generalization, suppression, k-anonymity, l-diversity, and t-closeness. Homomorphic encryption, SMPC, differential privacy, and federated learning concepts and applications are also presented, citing their efficacy in protecting sensitive data while enabling data analysis collaboration. In order to emphasize the significance of privacy-preserving strategies in real applications, the study surveys real implementations in sectors such as healthcare, finance, telecommunication, social media, and government. Besides unveiling main issues such as scalability, usability, and adversarial attack resistance, the current study also presents potential future research directions for further development in this area. The current work endeavors to contribute to scholars, policymakers, and practitioners with a profound understanding of advancing ethical and sustainable data-driven decision-making by presenting an in-depth review of privacy preserving methods and their ethical implications.
