Abstract Higher Education (HE) institutions and Lifelong Learning (LLL) providers increasingly issue digital certificates, yet prevailing solutions often lack interoperable credential schemas, verifiable provenance, and privacy-preserving verification at scale. In parallel, European initiatives promote verifiable credentials and cross-border recognition, but there is limited evidence on how Hyperledger Indy components—Redundant Byzantine Fault Tolerance (RBFT) consensus, Decentralized Identifiers (DIDs), Anonymous Credentials (AnonCreds), and revocation registries—can be integrated into existing learning platforms while satisfying software service-quality and governance requirements. This paper presents a permissioned, privacy-preserving blockchain architecture for secure issuance and verification of educational verifiable credentials (VCs) and evaluates… More >

Abstract With the rapid expansion of the Internet of Medical Things (IoMT), the importance of digital identity–based security has significantly increased. However, conventional static authentication mechanisms are insufficient to effectively address various identity misuse and abuse attacks. In this study, we model digital identity as a dynamic security entity and propose an AI-based framework that integrates a risk scoring model—combining unsupervised anomaly detection with context-aware analysis—and a multi-level risk-adaptive access control mechanism (Permit, Step-Up, Restrict). Experimental results using an extended version of the CERT Insider Threat Dataset tailored for IoMT environments provide proof-of-concept evidence that the More >

Abstract Unmanned aerial vehicles (UAVs) are becoming a common solution to urban mobility, and traffic monitoring as well, owing to their ability to be deployed flexibly, ability to see a broader area and real-time sensing. However, the reliability of UAV-assisted traffic systems can be compromised through identity spoofing, Sybil attacks, false data injection, and trajectory manipulation. Current authentication techniques primarily verify cryptographic identities but often cannot detect when a claimed identity is inconsistent with physical movement patterns and settings. To overcome this drawback, this paper presents a context-aware identity validation system, CIV-UAV, for UAV-based urban traffic… More >

Abstract This study examined the mediating role of perceived supervisor–student relationship quality and the moderating role of student extraversion in the relationship between supervisor conscientiousness and graduate students’ professional identity. A total of 450 graduate students completed surveys of supervisor conscientiousness, perceived supervisor–student relationship quality, professional identity, and extraversion. Results of a moderated mediation model testing showed that supervisor conscientiousness was associated with higher graduate students’ professional identity. Perceived supervisor–student relationship quality mediated this association, with higher supervisor conscientiousness linked to better perceived supervisor–student relationship quality, which in turn related to higher levels of professional identity.

Abstract Secure IoT ecosystems are based on the notion that device authentication is reputable. Traditional approaches typically use software identifiers or stored cryptographic keys, which can be cloned, copied, or modified by physical access or supply-chain interference. The current paper presents a hardware fingerprinting system that is based on compliance to enhance the strength of the authentication of the IoT device, that is, to connect physical device properties with organized conformity practices. The tool exploits intrinsic electrical and manufacturing differences in parts to produce device-specific fingerprints and compares these fingerprints with compliance processes, including component validation, More >

Abstract Quantum Key Distribution (QKD) ensures secure key establishment through the principles of quantum mechanics; however, its effectiveness in practice hinges on dependable identity verification via classical channels during the post-processing phase. Current QKD implementations typically depend on pre-existing symmetric-key authentication, which suffers from limited scalability and complicated key management in extensive networks. Authentication methods utilizing post-quantum cryptography (PQC) signatures, based on complex mathematical assumptions, introduce extra and uncertain security dependencies, potentially compromising the security model integrity that QKD aims to maintain. This paper explores the application of hash-based signatures (HBS) for identity verification in the… More >

Abstract This study investigated the association between helicopter parenting and malevolent creativity among college students, and the serial mediating roles of family environment and moral identity. The study sample comprised 489 Chinese college students (females = 56.2%, 18–23 years old = 87.1%). The students completed self-report measures assessing helicopter parenting, family environment, moral identity, and malevolent creativity. The results of serial mediation model showed that helicopter parenting was significantly associated with higher malevolent creativity. Moreover, family environment and moral identity sequentially mediated this relationship. Specifically, helicopter parenting may contribute to a negative family environment and undermine More >

Abstract Recognizing frontal faces from non-frontal or profile images is a major problem due to pose changes, self-occlusions, and the complete loss of important structural and textural components, depressing recognition accuracy and visual fidelity. This paper introduces a new deep generative framework, Modified Multi-Scale Fused CycleGAN (MMF-CycleGAN), for robust and photo-realistic profile-to-frontal face synthesis. The MMF-CycleGAN framework utilizes pre-processing and then the generator employs a Deep Dilated DenseNet encoder-based hierarchical feature extraction along with a transformer and decoder. The proposed Multi-Scale Fusion PatchGAN discriminator enforces consistency at multiple spatial resolutions, leading to sharper textures and improved More > Graphic Abstract

Abstract Background: Emerging adulthood is a critical period for ego identity exploration and consolidation, and self-presentation on social media constitutes a salient online context for this developmental process. However, limited research has explored the associations between self-presentation on WeChat Moments and ego identity. This study aims to examine these associations, focusing on the mediating role of online positive feedback and the moderating role of gender. Methods: Using a three-wave longitudinal design, this study followed 767 Chinese college students (Mean age = 18.96 years) through cluster sampling. Participants completed self-report questionnaires assessing self-presentation on WeChat Moments, online positive… More >

Abstract In the rapidly evolving digital landscape, the interplay between social media and cultural identity among Afghan youth is of growing significance. This study examines how social media influences the digital culture of Afghan youth, using Social Identity Theory (SIT) to explore digital behaviors, identity formation, and cultural preservation. With a sample of 400 participants, the research addresses key gaps by analyzing the impact of social media on societal norms, cultural values, and online relationships. The findings highlight social media’s pivotal role in shaping Afghan digital culture, with a particular emphasis on the active engagement of More >
