“…Another research direction is how to ensure that avatars themselves, as digital entities, can be protected from unauthorized access by imposters, and how the identity of the users can be managed within the social VR system. Although some authors have called for access control and identity management for avatars in social VR (Gavrilova and Yampolskiy, 2010;Yampolskiy et al, 2012;Bader and Ben Amara, 2014a;Bader and Ben Amara, 2016;Bader and Ben Amara, 2017;Freeman et al, 2020) are the only authors we found that explored this topic and proposed technical solutions.…”

“…In response to the problems mentioned above, we hope to find corresponding protection mechanisms or potential countermeasures in the literature. While 13 papers (Gavrilova and Yampolskiy, 2010;Boukhris et al, 2011;Mohamed and Yampolskiy, 2012;Yampolskiy et al, 2012;Bader and Ben Amara, 2014a;Bader and Ben Amara, 2014b;Bader and Ben Amara, 2016;Bader and Ben Amara, 2017;Falchuk et al, 2018;Pfeuffer et al, 2019;John et al, 2020;Lake, 2020) have explicitly addressed one or several identity and privacy issues and proposed corresponding protection mechanisms, works that have presented techniques or design guidelines that provide potential solutions in the area of virtual reality are also included and analyzed. Based on their characteristics and objectives, we have subdivided them into the following categories.…”

“…The protection of identity and the protection of digital bodies might be two separate aspects of the problems that together form a link between users, digital identities, and digital bodies. The idea of utilizing watermarking for avatar protection proposed by Bader and Ben Amara (2014a) deserves further exploration, and some recent studies on 3D mesh watermarking can be referred to (Ali, 2019;Malipatil and Shubhangi, 2020;Beugnon et al, 2022;Yoo et al, 2022).…”

Social Virtual Reality (social VR or SVR) provides digital spaces for diverse human activities, social interactions, and embodied face-to-face encounters. While our digital bodies in SVR can in general be of almost any conceivable appearance, individualized or even personalized avatars bearing users’ likeness recently became an interesting research topic. Such digital bodies show a great potential to enhance the authenticity of social VR citizens and increase the trustworthiness of interpersonal interaction. However, using such digital bodies might expose users to privacy and identity issues such as identity theft: For instance, how do we know whether the avatars we encounter in the virtual world are who they claim to be? Safeguarding users’ identities and privacy, and preventing harm from identity infringement, are crucial to the future of social VR. This article provides a systematic review on the protection of users’ identity and privacy in social VR, with a specific focus on digital bodies. Based on 814 sources, we identified and analyzed 49 papers that either: 1) discuss or raise concerns about the addressed issues, 2) provide technologies and potential solutions for protecting digital bodies, or 3) examine the relationship between the digital bodies and users of social VR citizens. We notice a severe lack of research and attention on the addressed topic and identify several research gaps that need to be filled. While some legal and ethical concerns about the potential identity issues of the digital bodies have been raised, and despite some progress in specific areas such as user authentication has been made, little research has proposed practical solutions. Finally, we suggest potential future research directions for digital body protection and include relevant research that might provide insights. We hope this work could provide a good overview of the existing discussion, potential solutions, and future directions for researchers with similar concerns. We also wish to draw attention to identity and privacy issues in social VR and call for interdisciplinary collaboration.

“…Accordingly, digital watermarking has emerged as an alternative to overcome the aforementioned limitations. Watermarking is defined as the process of invisibly incorporating a watermark in a digital content and may be used for a lot of applications, including copyright protection, copy control, indexing, authentication and integrity, E‐commerce, broadcast control, transaction management, and copyright communication . For the authentication and integrity preservation of biometric data, a first biometric modality is used as a host and receives a watermark that can be a second biometric modality which will consolidate the recognition performance of the system.…”

The integration of data privacy and security into radio frequency identification (RFID) technology, particularly into RFID tags, has become one of the most attractive research areas. A crucial challenge in RFID technology research lies in providing an efficient protection for systems against information theft and illegitimate access. This article proposes a secure solution based on an RFID card for physical biometric access-control applications. This is done by integrating two biometric modalities, namely face and fingerprint which are secured via a double watermarking technique. The suggested approach is ensured by two levels of watermarking. At the first level, the wavelet packet decomposition watermarking algorithm is used to insert features from the fingerprint (minutiae) in the face image of an authorized person. At the second level, the same watermarking algorithm is employed to insert the fingerprint watermark in the face features extracted by Gabor filters from the previously watermarked face image (at the first level). The obtained secured watermarked biometric data are then integrated in a 1-kB high frequency proximity RFID card. This combination of both RFID technology and the double watermarking technique provides a biometric control access framework.Compared with the state-of-the-art frameworks, the proposed one ensures a good compromise between a reduced computational complexity and a high level of data security while maintaining a small space of storage and a low cost compared to those of the marketed products.

In the domain of Extended Reality (XR), particularly Virtual Reality (VR), extensive research has been devoted to harnessing this transformative technology in various real-world applications. However, a critical challenge that must be addressed before unleashing the full potential of XR in practical scenarios is to ensure robust security and safeguard user privacy. This paper presents a systematic survey of the utility of biometric characteristics applied in the XR environment. To this end, we present a comprehensive overview of the different types of biometric modalities used for authentication and representation of users in a virtual environment. We discuss different biometric vulnerability gateways in general XR systems for the first time in the literature along with taxonomy. A comprehensive discussion on generating and authenticating biometric-based photorealistic avatars in XR environments is presented with a stringent taxonomy. We also discuss the availability of different datasets that are widely employed in evaluating biometric authentication in XR environments together with performance evaluation metrics. Finally, we discuss the open challenges and potential future work that need to be addressed in the field of biometrics in XR.
