Privacy, Security & Governance Frameworks for AI-Powered Wearable Internet of Health Things in Elderly Care: A Comprehensive Review
Abstract
The global aging population is expanding at an unprecedented rate, with projections indicating that 1.4 billion people will be aged 60 years or older by 2030 and 2.1 billion by 2050, placing immense pressure on healthcare systems worldwide. Artificial intelligence (AI)-powered wearable Internet of Health Things (IoHT) devices - including smartwatches, biosensors, and continuous health monitors - have emerged as transformative tools for real-time elderly health monitoring, fall detection, and predictive analytics. However, the massive collection of sensitive biometric data by these devices raises critical concerns regarding privacy, security, and governance that remain insufficiently addressed, particularly for elderly populations. This comprehensive review synthesizes evidence from 333 peer-reviewed articles published between 2018 and 2025 cross PubMed, Scopus, Web of Science, IEEE Xplore, and Google Scholar to identify, analyze, and compare governance frameworks for AI-powered wearable IoHT in elderly care. The analysis reveals significant regulatory fragmentation across jurisdictions: while the European Union's General Data Protection Regulation (GDPR) and AI Act provide the most comprehensive rights-based framework, the United States relies on a patchwork of sector-specific regulations with notable gaps for consumer wearables, and Asia-Pacific nations exhibit highly variable approaches ranging from mature (Singapore, Japan) to nascent (Indonesia, Malaysia).…
