Abstract
from arXiv · showhide
The metaverse promises a host of bright opportunities for business, economics, and society. Though, a number of critical aspects are still to be considered and the analysis of their impact is almost non-existent. In this paper, we provide several contributions. We start by analysing the foundations of the metaverse, later we focus on the novel privacy and security issues introduced by this new paradigm, and finally we broaden the scope of the contribution highlighting some of the far-reaching yet logical implications of the metaverse on a number of domains, not all of them in tech. Throughout the paper, we also discuss possible research directions. We believe that the provided holistic view on the foundations, technology, and issues related to the metaverse-with a focus on security and privacy-, other than being an interesting contribution on its own, could also pave the way for a few multidisciplinary research avenues.
I. INTRODUCTION
The paper introduces the metaverse as a persistent, shared 3D virtual universe integrated with the physical world. It examines how emerging technologies expand this vision while transforming security and privacy concerns.
- The metaverse combines persistent, multi-user, shared 3D virtual spaces intertwined with the physical world.Users enter through avatars that interact with other users, objects, applications, services, and businesses.
- Major technology firms have recently invested in ambitious metaverse development efforts.The paper cites Microsoft, Epic Games, and Meta among these firms.
- VR will create immersive 3D spaces, while AR will integrate virtual and physical worlds.Digital twins and wearable sensors are also identified as enabling technologies for representing objects and movements.
- The metaverse’s combination of social media, algorithms, sensory systems, and extensive data makes security and privacy concerns both magnified and transformed.The paper frames these concerns as part of broader critical issues requiring further analysis.
A. Contributions

B. Roadmap
The paper proceeds from background and related work to metaverse issues, broader criticalities and research directions, and concluding remarks. It describes the metaverse as an extensible substrate connecting diverse applications.
- Roadmap: Section II reviews background information and related work on the metaverse.
- Roadmap: Section III discusses current metaverse issues, specifically security and privacy.
- Roadmap: Section IV analyzes stringent criticalities and identifies broad research directions based on the paper’s guiding principles.
- Roadmap: The paper concludes with remarks on the implications of the metaverse.
- Core elements: The metaverse is presented as a virtual universe or substrate capable of supporting and interconnecting many applications.Its possible user activities therefore vary with the applications embedded within it.
2) Immersiveness:
The metaverse extends access beyond screen-based mobile devices through AR and VR, combining pervasiveness and immersiveness with interoperability across applications and spaces.
- Immersiveness: AR and VR expand access to online virtual spaces beyond screens and mobile devices.These technologies support the metaverse’s merge between virtual and physical worlds.
- Immersiveness: Pervasiveness and immersiveness distinguish the metaverse by changing how users access, interact with, and receive feedback from it.
- Immersiveness: Interoperability connects the metaverse’s applications and services from an architectural perspective.
- Immersiveness: Users may be able to use virtual items across applications and spaces throughout the metaverse.The paper gives NFTs purchased in one application as an example of potentially portable items.
B. Beyond Current Technology
The metaverse is expected to extend beyond established technology through advanced interfaces and multisensory interaction, while its immersiveness and interoperability increase associated threats.
- B. Beyond Current Technology: Advanced functionality analysis is needed to understand the full extent of opportunities and challenges resulting from the metaverse.
- B. Beyond Current Technology: Brain–computer interfaces could convert neural activity into computer inputs and potentially influence the brain, expanding metaverse interaction beyond conventional devices.The paper notes both noninvasive and implanted BCI research, while emphasizing their potential to free users from mouse-and-keyboard constraints during VR sessions.
- B. Beyond Current Technology: The metaverse is envisioned as a multisensory Internet 3.0 experience involving images, videos, and other forms of feedback.
- B. Beyond Current Technology: Its unprecedented immersiveness and interoperability also increase the quantity and quality of threats associated with the technologies used to realize it.
A. Privacy
The metaverse extends the data-driven platform model of today’s Internet, making users, content, activity, and services part of a unified environment for intensified data collection and monetization.
- A. Privacy: Today’s social platforms provide free services by collecting detailed user preferences that support accurate, microtargeted advertising.
- A. Privacy: In the metaverse, the platform model expands so that literally everything and everyone can become part of the product.
- A. Privacy: Metaverse data collection is expected to surpass current web tracking by analyzing users’ movements, attention, interactions, and preferences in more extensive ways.
2) User privacy:
Metaverse privacy risks span personal information, behavior, and communications, with immersive connectivity creating new opportunities for misuse, harassment, fraud, and offline harm. Proposed countermeasures give users privacy choices, but existing solutions may not scale to complex multiverses.
- 2) User privacy:: Metaverse privacy concerns involve three areas: personal information, behavior, and communications, each supplying platforms with more data and increased risks.
- 2) User privacy:: Immersive experiences can enable online interactions to be exploited for offline harms and frauds, including social engineering attacks.
- 2) User privacy:: Coordinated harassment, raiding, shaming, cyberbullying, video call bombing, and shitstorming may proliferate in the metaverse.
- 2) User privacy:: More interpersonal connections increase ways information can be collected or misused and cyber-crimes can be perpetrated through communications.
- 2) User privacy:: Proposed privacy strategies include avatar mannequins or clones, private copies of public spaces, and user-selectable privacy controls.
- 2) User privacy:: Existing privacy solutions were designed for simplistic metaverses and may be insufficient for complex, immersive, massively interconnected multiverses.
B. Security
The metaverse’s technological scale and complexity are expected to generate additional security threats, increasing reliance on algorithmic automation and raising unresolved technical and legal questions about algorithmic responsibility.
- B. Security: Combining powerful technologies in the metaverse will generate security threats in addition to its privacy issues.
- B. Security: A platform connecting far more users, services, applications, goods, and data will require administrators to automate more tasks with algorithms.
- B. Security: Delegating more life activities to algorithms creates open questions about how their security challenges should be addressed.
- B. Security: Addressing algorithm-related security challenges will require new technical methodologies and solutions alongside legal approaches to responsibility and cost externalization.
2) Integrity and authentication in the metaverse:
The metaverse intensifies integrity and authentication challenges through algorithmically managed content and users, while its singleton structure concentrates diverse users and interactions in a few massive platforms.
- Algorithmic management creates integrity and authentication risks through fabricated content, fake personas, and automated accounts.
- A singleton metaverse aggregates applications, services, goods, and users through a centralized access point, unlike the Web’s plurality of platforms.
- Replacing diverse Web communities with a handful of massive metaverses will bring users with peculiar interests and opposed viewpoints into simultaneous interaction.
IV. DISCUSSION
The discussion frames the metaverse through technological singularity: converging technologies and massive data may produce qualitative transformation, requiring multidisciplinary analysis to anticipate novel risks.
- The paper uses singularity to describe technological growth becoming uncontrollable and irreversible, with unforeseeable changes to human civilization.
- The metaverse may qualify as a qualitative transformation because technologies, platforms, sensory systems, and large-scale data converge in one domain.
- Anticipating the metaverse’s novel risks requires methodologies from computer science, engineering, philosophy, law, psychology, and other disciplines.
- Failing to anticipate the metaverse’s complexity could create a false sense of control in which novel elements generated by singularity are ignored.
- The paper presents its singularity framing as a basis for concluding remarks expected to raise more questions than solutions.
V. CONCLUSIONS
The conclusions argue that the metaverse emerges from the combination of advancing technologies, producing security, privacy, and broader complex issues that require multidisciplinary study.
- The metaverse is framed as emerging from converging technological advances rather than solely from business opportunity or communication campaigns.
- Combining metaverse technologies may change technological and cognitive landscapes both quantitatively and qualitatively.
- Security and privacy threats in the metaverse may partly escape existing logical and technological approaches.
- The metaverse raises complex issues extending partially beyond the technical domain, motivating a broad and multidisciplinary approach.
