我们目睹了人类历史上人口老龄化的空前增长。确保独居老人的健康和安全并非易事。高昂的人力成本需要更可持续的、以技术为导向的方法，而不是劳动密集型解决方案。利用医疗物联网（IoMT），数字孪生（DT）和先进的第五代及以后（B5G）无线通信技术的数字医疗服务（DHS）被广泛认为是有前途的解决方案。通过实现物理世界和网络空间的无缝交织，Metaverse为下一代国土安全部提供了理想的家园。由于去中心化，可追溯性和不可更改性的特点，区块链被认为可以增强Metaverse的安全属性。本文提出了MetaSafe，在Metaverse的老年人安全监控DHS架构。基于传感器收集的监测数据，老年人的活动和状态，谁被认为是物理对象（PO），被镜像到相应的逻辑对象（LO）在虚拟社区中的Metaverse，在那里活动识别，潜在的风险预测，并生成警报。通过利用不可替代令牌（NFT）技术在区块链上对DHS的身份（PO和LO）和数据流进行令牌化，基于NFT的身份验证结构允许在数据共享过程中实现可验证的所有权和可追溯的可转移性。具体而言，在这项工作中引入了一个即时警报系统，该系统利用了将奇异谱分析（SSA）方法与长短期记忆（LSTM）网络相结合的混合算法。通过大量的实验研究，MetaSafe被证明是一种可行的和有前途的方法来保护独居老人。
We have been witnessing an unprecedented increase in the aging population in human history. It is nontrivial to ensure the health and safety of seniors living alone. The prohibitive human labor cost necessitates more sustainable, technology-oriented approaches instead of labor-intensive solutions. The raising digital healthcare services (DHS) leveraging the Internet of Medical Things (IoMT), Digital Twins (DT), and advanced fifth-generation and beyond (B5G) wireless communication technology, are widely recognized as promising solutions. By enabling a seamless interwoven of the physical world and cyberspace, Metaverse makes an ideal home for the next generation of DHS. Thanks to characteristics of decentralization, traceability, and unalterability, Blockchain is envisioned to enhance security properties in Metaverse. This paper proposes MetaSafe, a DHS architecture for seniors’ safety monitoring in Metaverse. Based on monitoring data collected by sensors, the activities and status of seniors, who are considered as the physical objects (PO), are mirrored to corresponding logical objects (LO) in a virtual community in the Metaverse, where activity recognition, potential risk prediction, and alert generation are realized. By leveraging Non-Fungible Token (NFT) technology to tokenize identities (POs and LOs) and data streams of the DHS on the blockchain, an NFT-based authentication fabric allows for verifiable ownership and traceable transferability during the data-sharing process. Specifically, an instant alerting system is introduced in this work that leverages a hybrid algorithm combining the singular spectrum analysis (SSA) approach with the long-short-term memory (LSTM) networks. Through an extensive experimental study, MetaSafe is validated as a feasible and promising approach to protect seniors living alone.
