摘要

在各领域技术进步(人工智能、5G、VR、物联网等)以及数字孪生技术(HDT、HAL、BIM 等)出现的推动下,元宇宙吸引了科学界和工业界越来越多的关注。人们之所以对其感兴趣,是因为它可能对教育或医疗等不同领域的人们的生活产生影响。具体的解决方案还可以提高对残疾人的包容性,因为他们的残疾阻碍了他们的充实生活。然而,安全和隐私问题仍然是其发展的主要障碍。特别是,元宇宙所涉及的数据可能非常全面,其粒度足以建立一个高度详细的现实世界数字副本,包括一个人的人类数字孪生体。现有的安全对策大多无效,而且无法适应元宇宙应用的特殊需要。此外,大规模元宇宙中的虚拟世界在硬件实现、通信接口和软件方面可能千差万别,这给互操作性带来了巨大困难。本文旨在分析在元宇宙中采用人类数字复制品(HDT)的相关风险和机遇,以及在此背景下与数字身份管理相关的挑战。通过研究当前的技术状况,我们发现了目前限制 HDT 和 Metaverse 应用的几项公开技术挑战。此外,本文还探讨了一系列有前途的技术和方法,以评估它们在元宇宙中的适用性。最后,本文介绍了医疗和教育领域的两个示例方案。

Metaverse & Human Digital Twin: Digital Identity, Biometrics, and Privacy in the Future Virtual Worlds
Driven by technological advances in various fields (AI, 5G, VR, IoT, etc.) together with the emergence of digital twins technologies (HDT, HAL, BIM, etc.), the Metaverse has attracted growing attention from scientific and industrial communities. This interest is due to its potential impact on people lives in different sectors such as education or medicine. Specific solutions can also increase inclusiveness of people with disabilities that are an impediment to a fulfilled life. However, security and privacy concerns remain the main obstacles to its development. Particularly, the data involved in the Metaverse can be comprehensive with enough granularity to build a highly detailed digital copy of the real world, including a Human Digital Twin of a person. Existing security countermeasures are largely ineffective and lack adaptability to the specific needs of Metaverse applications. Furthermore, the virtual worlds in a large-scale Metaverse can be highly varied in terms of hardware implementation, communication interfaces, and software, which poses huge interoperability difficulties. This paper aims to analyse the risks and opportunities associated with adopting digital replicas of humans (HDTs) within the Metaverse and the challenges related to managing digital identities in this context. By examining the current technological landscape, we identify several open technological challenges that currently limit the adoption of HDTs and the Metaverse. Additionally, this paper explores a range of promising technologies and methodologies to assess their suitability within the Metaverse context. Finally, two example scenarios are presented in the Medical and Education fields.
