Advancing technology for a healthier humanity

March 1, 2020 by Cátia Bandeiras

Medical technology (MedTech) includes the products, services, or solutions that aim at improving survival and quality of life. These technologies can include preventive, diagnostic, or therapeutic technologies. Key technologies in this space include medical devices, in vitro diagnostics, medical imaging, prosthetics and orthotics, medical signal processing, health informatics and communications technologies, wearables, medical robotics, and regenerative medicine. According to the IQVIA’s “The Rise of Global Medical Technology” report, MedTech worldwide is an extremely valuable market, with an estimated global revenue of US$438 billion in 2017. This is a fast-growing industry, with a compound annual growth rate of 6%, and it is estimated to reach US$585 billion in 2022.

Privacy-preserving distributed learning: Techniques, applications, and future challenges

The rapid increase in data generated by connected devices has created a pressing need for privacy-preserving techniques in distributed learning. This article examines methods that enable collaborative machine learning (ML) while maintaining data security and user privacy. Key approaches such as federated learning (FL), differential privacy (DP), secure multiparty computation (SMPC), and homomorphic encryption (HE) are analyzed for their unique capabilities and various applications. FL facilitates model training across decentralized data sources, ensuring data remain local, while DP mitigates privacy risks by adding controlled noise. SMPC and HE support secure computations on encrypted data, maintaining confidentiality during processing. Despite their effectiveness, these techniques face challenges related to computational complexity, scalability, and regulatory compliance. The article reviews current advancements, practical implementations, and future directions, emphasizing the need for optimized, accessible solutions to enhance data security in distributed systems.
