Facial expressions can provide a better understanding of people's mental status and attitudes towards specific things. However, facial occlusion in real world is an unfavorable phenomenon that greatly affects the performance of facial expression recognition models. Recent works addressing the occlusion problem have primarily relied on attention mechanisms or occlusion discarding methods that focus on non-occluded regions of the face. However, these methods have not achieved a good balance between occlusion robustness and model efficiency. In this paper, we propose a simple and efficient model, called FERMixNet, for occluded facial expression recognition. The model incorporates a novel facial mixing augmentation strategy (FERMix) that generates new training samples by simulating real-world facial occlusion and preserving high expression-related semantic information. By co-training the original and newly generated samples, the model's occlusion robustness is improved without increasing its complexity during inference. Additionally, to further enhance the model's occlusion robustness, we include mid-level representation learning in the network to learn the discriminative non-occluded local features of the samples with low computational cost. Extensive experiments on four public facial occlusion datasets: Occlusion-RAF-DB, Occlusion-FERPlus and FED-RO show that the proposed model achieves state-of-the-art results which demonstrates the good robustness of our method for occluded facial expression recognition. Meanwhile, the proposed model also achieves state-of-the-art results on the in-the-wild facial expression datasets RAF-DB, AffectNet-8, and AffectNet-7. It proves that the proposed model has good application prospects in real world. © 2010-2012 IEEE.

Optical Character Recognition of handwritten document has been a research topic for last few decades now. Different type of classification schemes starting from template matching, structural analysis to deep neural network have been proposed by researchers. In this paper, a novel holistic approach is proposed for recognition of handwritten words. The approach is a hybrid model combining CNN and BLSTM layers which are responsible for extraction of spatial and temporal features respectively from the word images. Both the features are combined by compact bi-liner pooling. The CBP layer highlights the fine grained details which in turn help to achieve high recognition accuracy. The extracted feature is recognized by a connectionist temporal classification layer. The weights are learnt based on the database using the back propagation algorithm. The hybrid model is trained using three public databases CMATERdb2.1.2, IIIT-HW-Dev and IIIT-HW-Telugu containing Bengali, Devanagari and Telegu handwritten words respectively. The proposed model has achieved 96.42%, 94.79%, 95.07% accuracy on the Bengali, Devanagari and Telegu databases respectively. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd 2024.

Quantum Key Distribution or QKD revolutionizes secure communication using quantum mechanics. Unlike traditional cryptographic methods vulnerable to advances in computing power, QKD guarantees unconditional security by detecting any eavesdropping attempt. Quantum Key Distribution (QKD) constitutes a through development in the realm of secure communications by utilizing the ideas of quantum mechanics to provide potentially unbreakable encryption. This study examines the most current advancements in QKD, including the recently announced Measurement-Device-Independent QKD (MDI-QKD) and protocols like BB84 and E91. We analyze the real-world implementation, including satellite-based QKD and quantum repeaters. Furthermore, we discuss the challenges and opportunities of integrating QKD into present communication infrastructure. The significance of QKD in attaining secure communication networks for the next generation is underscored by our findings, which also have ramifications for forthcoming research and applications. Ultimately, this research aims to contribute to the development of robust and impenetrable communication networks in an increasingly interconnected world. © 2024 IEEE.

Credential management for emergency scenarios is vital for security, access control, accountability, and ensuring the effectiveness of response and recovery efforts while adhering to regulatory requirements. In the aftermath of a disaster or any emergency scenario, control stations/regulatory authorities access several response and recovery systems for providing services. Unauthorized access to these systems creates cyber-attacks. Also, the existing credentials management systems suffer from time-consuming procedures due to the involvement of numerous stakeholders and restricted information access, leading to increased administrative burden, and loss of trust and reputation in the system. As a result, several researchers and emergency response organizations have advised to use of blockchain technology which provides a secure, transparent, and tamper-proof ledger of credentials and access logs. This immutability ensures that no unauthorized changes or deletions occur, enhancing the trustworthiness of the credential data. Hence, this work exploits the concept of blockchain to enrich the credential management system by streamlining the validation mechanism and upgrading security mechanisms. This work develops BCredS, a blockchain-leveraged secure and intelligent credential management system by designing smart contracts that are resistant to hacking, and by utilizing blockchain, the security of the application will be improved since it employs strong cryptographic techniques. The efficiency of the proposed work will be evaluated through extensive simulation in Ethereum platform. © 2024 IEEE.

As the network security landscape changes with time and market, organizations seek different and innovative approaches to strengthen their security defenses. This paper gives a theoretical explanation, highlighting the combination of honeypots and network monitoring tools as a dynamic strategy for enhancing security within networking environments. By using honeypots along with network monitoring tools, we bring out a multilayered defense strategy aimed at identifying and examining potential attack patterns. Our research dives into the theory of honeypots, their role in diverting malicious attacks, and their relationship with network monitoring tools. This combined framework helps organizations to detect, analyze, and ultimately reduce security threats. Through theoretical inputs and suggestions, this paper presents a framework for organizations seeking to enhance their cybersecurity defenses by exploring the complications of attacks through advanced network monitoring, along with honeypot security mechanisms. © 2024 Bharati Vidyapeeth, New Delhi.
