The evolution of technology has a significant impact on health data collection, transforming the way information is gathered, stored, and utilized in the healthcare industry. The big health record contains sensitive user information like contact details, health status, demographics, vaccination details, exposure history. It's worth noting that while the collection of big health records has been crucial for monitoring the patients' health history, it also raises important privacy and security considerations. Safeguarding the privacy of individuals' health data and ensuring compliance with relevant regulations is essential to maintain public trust and protect sensitive information. Therefore, healthcare data must adhere to privacy regulations and ethical considerations. This chapter elaborates on key challenges and solutions in privacy preservation within federated learning. The key challenges include data heterogeneity, information leakage, attacks, and regulatory compliances.
Top1. Introduction
In the era of the digital world, healthcare is being digitalized at an increasingly rapid pace. The advancements in technology have revolutionized the healthcare industry, transforming the way healthcare services are delivered, accessed, and managed. The digitalization uses digital technologies and information systems to improve patient care, the delivery of healthcare, and administrative processes. It involves the use of various technologies, such as electronic health records (EHRs), telemedicine, health apps, wearable devices, artificial intelligence (AI), data analytics, Virtual Reality (VR) and Blockchain.
The key aspects and benefits of healthcare digitalization includes Electronic Health Records (EHRs), Telemedicine, Health Apps and Wearable devices, Artificial Intelligence and Data Analytics, Virtual Reality and Augmented Reality, and Blockchain. Electronic Health Records (EHRs): EHRs replace traditional paper-based records with electronic systems that store and manage patient health information. They enable efficient and secure sharing of medical records among healthcare providers, reducing errors, improving coordination, and enhancing patient safety. Telemedicine: Telemedicine allows patients to receive medical consultations and treatments remotely using digital communication tools. It improves access to healthcare, particularly for individuals in rural or underserved areas, reduces travel time and costs, and enables remote monitoring of patients' health conditions. Health Apps and Wearable Devices: Mobile health applications and wearable devices enable individuals to monitor their health, track fitness levels, and manage chronic conditions. These tools provide real-time data, encourage self-care, and empower patients to take an active role in their healthcare.
Artificial Intelligence (AI) and Data Analytics: AI technologies can analyze vast amounts of healthcare data, identify patterns, and generate insights for clinical decision-making. AI-powered algorithms can help in diagnosing diseases, predicting outcomes, and recommending personalized treatment plans. Data analytics can also be utilized to improve operational efficiency, identify trends, and enhance population health management. Virtual Reality (VR) and Augmented Reality (AR): VR and AR technologies have applications in medical training, patient education, and surgical planning. They offer immersive and interactive experiences, allowing medical professionals to practice complex procedures in a realistic virtual environment. Blockchain: Blockchain technology has the potential to improve data security, privacy, and interoperability in healthcare. It can enhance the integrity of medical records, enable secure sharing of sensitive data, and facilitate streamlined processes, such as insurance claims and supply chain management.
The benefits of healthcare digitalization include:
- •
Improved access to healthcare services, especially for underserved populations.
- •
Enhanced patient engagement and empowerment.
- •
Enhanced communication and collaboration among healthcare providers.
- •
Increased efficiency and accuracy of medical records and administrative processes.
- •
More personalized and precise treatment plans.
- •
Early detection and prevention of diseases.
- •
Cost savings through streamlined operations and reduced hospital readmissions.
It is to be noted that healthcare organizations collect and generate a significant amount of data on a daily basis. This data comes from various sources such as electronic health records (EHRs), medical imaging, wearable devices, genomics, clinical trials, administrative systems, and more. The volume and complexity of healthcare data have grown exponentially with the digitalization of healthcare. However, it's important to address challenges related to data security, privacy, interoperability, and the digital divide to ensure equitable access to digital healthcare solutions for all individuals.
Top2. Federated Learning In Healthcare
Federated learning is a machine learning technique that enables a model to be trained across numerous decentralized servers or devices while maintaining the data on those servers or devices. When training machine learning models on sensitive data, concerns about privacy and data security were addressed by the emergence of federated learning.
