Digital Virtual Simulation for Cultural Clothing Restoration: Case Study of Tang Dynasty Mural ‘Diplomatic Envoys’ from Crown Prince Zhang Huai’s Tomb

The advent of 3D virtual presentation technology for clothing has led to the gradual popularisation of digital virtual clothing in the modern fashion industry. However, there remains a gap between the application of this technology and the integration of cultural attributes in the field of digital communication of traditional cultural clothing. Consequently, the objective of this paper is to propose the establishment of a fusion system integrating archaeological research on traditional culture with emerging virtual presentation technology. This paper draws inspiration from the replicability and easy dissemination of digital products to combine cultural archaeology and digital technology. The aim is to provide ideas for the diversity of dissemination of cultural heritage. The research object is Diplomatic Envoys, a Chinese mural painting of the Tang Dynasty that depicts friendly exchanges between countries. The research is divided into two research stages. A CLO3D software-based digital restoration test was conducted to reproduce the costumes of officials and foreign envoys depicted in the Tang Dynasty mural. The FAHP model was employed to verify the accuracy of the restoration results. The experiment demonstrated that the digitally reconstructed clothing exhibited a high degree of similarity to the unearthed mural figure clothing object. Furthermore, the restoration result passed the credibility verification, resulting in a ‘credible’ outcome. The application of digital virtual simulation clothing restoration methods offers two key advantages. Firstly, in comparison with traditional clothing restoration methods, digital restoration enables the rapid assessment of the resulting clothing effect, thereby reducing the likelihood of secondary damage to cultural relics due to manual errors. Secondly, the benefits of digital technology facilitate the convenient storage, replication, and dissemination of clothing data information. Data can not only be extended to online exhibition halls but also to game animation, clothing production, and other fields for the purposes of creative redesign and information dissemination. Furthermore, these benefits can penetrate the education industry to disseminate information to the public through all-round display models and explanations.

Blockchain-Based Secure and Efficient Secret Image Sharing With Outsourcing Computation in Wireless Networks

Secret Image Sharing (SIS) is the technology that shares any given secret image by generating and distributing <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</i> shadow images in the way that any subset of <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> shadow images can restore the secret image. However, in the existing SIS schemes, the shadow images will be easily tampered and corrupted during the communication, which will pose serious security issues. Recently, blockchain has emerged as a promising paradigm in the field of data communication and information security. To securely communicate and effectively protect the secret image data in wireless networks, we propose a Blockchain-based Secure and Efficient Secret Image Sharing (BC-SESIS) scheme with outsourcing computation in wireless networks. In the proposed BC-SESIS scheme, the shadow images are encrypted and stored in the blockchain to prevent them from being tampered and corrupted. The identity authentication-enabled smart contract is deployed to achieve the ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k, n</i> ) threshold for secret image restoring. Furthermore, to reduce the computational burden of smart contract and users, an efficient outsourcing computation method is designed to outsource the restoring task, which is securely implemented by agent miners in the encryption domain. Theoretical analysis and extensive experiments demonstrate that the BC-SESIS scheme can achieve desirable communication security and high computational efficiency in the wireless networks.

TOWARDS AN APPLIED ETHICS IN DIGITAL COMMUNICATION: A TRANSDISCIPLINARY PERSPECTIVE ON RESPONSIBILITY

In this article, we proposed an ethical analysis of the actors involved in digital communication, starting from the communication model developed by David Berlo. Thus, we identified the sources of transmission of a message, the characteristics of the message, the channels through which it is transmitted and which are the possible recipients, asking ourselves, through an exercise of applied ethics, what the responsibility of each one is. We argued that there are several ethical issues for each component of Berlo's model which can influence digital communication. Considering that ‘digital ethics’ is still a fairly narrow field, the transdisciplinary approach we proposed in this article has the advantage of opening up the area of applicability of ethics in the field of digital communication.

Research on digital native media: an emerging topic in the field of digital communication

Digital native media have gone through different stages since their emergence in the last decade of the twentieth century under the shadow of the evolution of the ‘network of networks’ and digital transformation. Despite the influence that legacy media have exerted on the models of many digital media, the efforts they have made to find their own way in the digital communication ecosystem have resulted in the introduction of new practices and strategies that have fuelled renewed debates on journalistic frontiers. The aim of this paper is to review the birth, evolution and current landscape of digital native media with special attention given to research in this field. This is an object of study with its own and differential characteristics in relation to legacy media, which attracts the focus of more and more digital communication researchers every day. To offer a current assessment of such research, a systematized review of articles published in scientific journals included in the Web of Science and Scopus databases was carried out. The results show that the conceptualization of digital native media, their mapping in media ecosystems and comparison with legacy media, the study of their typology and characteristics, research on their economic and organizational models, the analysis of their content, and their relationship with audiences are among the main objects of research. These media constitute a fundamental sector in the current media ecosystem, which will require multidisciplinary and interdisciplinary perspectives in their research to face the challenges of digital media, digital native media and digital journalism.

Performance Analysis of Turbo Codes, LDPC Codes, and Polar Codes over an AWGN Channel in the Presence of Inter Symbol Interference.

This paper discusses the results of simulations relating to the performances of turbo codes, low density parity check (LDPC) codes, and polar codes over an additive white Gaussian noise (AWGN) channel in the presence of inter symbol interference, denoting the disturbances that altered the original signal. To eliminate the negative effects of inter symbol interference (ISI), an equalizer was used at the level of the receiver. Practically, two types of equalizers were used: zero forcing (ZF) and minimum mean square error (MMSE), considering the case of perfect channel estimation and the case of estimation using the least square algorithm. The performance measure used was the modification of the bit error rate compared to a given signal to noise ratio; in this sense, the MMSE equalizer offered a higher performance than the ZF equalizer. The aspect of channel equalization considered here is not novel, but there have been very few works that dealt with equalization in the context of the use of turbo codes, especially LDPC codes and polar codes for channel coding. In this respect, this research can be considered a contribution to the field of digital communications.

An optimized ticket manager based energy‐aware multipath routing protocol design for IoT based wireless sensor networks

SummaryRecently, wireless sensor networks (WSNs) and Internet of Things (IoTs) have emanated as an indispensable assets that play a critical role in revolutionizing the field of data communication. Owing to the evolution of communication standards, research trends in IoT based wireless sensor networks have been rapidly progressing toward achieving effective data routing with a prolonged network lifetime and minimized energy consumption. In this article, an optimized ticket manager based energy‐aware multipath routing protocol (TMERP) is proposed. The proposed protocol design comprises three important functional entities: ticket manager (TM), routing planner (RP), and backup node (BN). The TM is responsible for controlling and monitoring all the constraints related to networking. Then, the RP minimizes the overall complexity of the optimal resource allocation by avoiding an end‐to‐end delay. Finally, the BN facilitates efficient data routing through the optimal selection of routing paths using the node trust evaluation and backup process to minimize data loss. Hence, the proposed multipath routing system has a distinct advantage in enhancing the network lifetime constraint with minimal energy consumption owing to the collective performance of its functional entities. The simulation results of the experimental studies show that the proposed protocol design achieved an improved performance in terms of network energy, throughput, and network operational lifetime by 39.3%, 47.9%, and 10.5%, respectively when compared with similar existing protocols.

Therefore, it is efficient to be used in data encryption for applications that run over limited resources such as the Internet of Things (IoT). In this paper, different digital watermarking algorithms and approaches are presented. Additionally, watermarking requirements and challenges are illustrated in detail. Moreover, the common architecture of the watermarking system is described. Furthermore, IoT technology and its challenges are highlighted. Finally, the paper provides the motivations, objectives and applications of the recent secure watermarking techniques in IoT and summarises them into one table. In addition, the paper highlights the potential to apply the modified watermark algorithms to secure IoT networks.

Diversity Enhancement of MIMO System with GA Optimized Linear Precoding of Orthogonal Space-Time Block Codes

The MIMO (Multiple-Input Multiple-Output) systems in the field of digital communications make it possible to improve data transmission according to two main parameters which are often antagonistic: the information rate and the transmission reliability estimated in average binary error probability (BEP) term. With such systems, CSI (Channel State Information) on transmission is a key point for reducing the BEP thanks to different power allocation strategies. Thus, a linear precoder on transmission associated with a linear decoder on reception can optimize a particular criterion thanks to this information. This paper proposes a MIMO system with precoded orthogonal space-time block codes (OSTBC) optimized by Genetic Algorithm with ZF and MMSE equalization. The performance evaluation is achieved by BER vs. SNR graphs.

Signature Text,Image and Audio Hiding in a Color Image using Steganography and Cryptography

Data Transmission in network security is one of the foremost vital issues in today’s communication world. the end result of that’s that Data security has gained utmost importance because of the unprecedented increase within the data generated over the web, which could be a basic necessity of any application in information technology. The vigorous growth within the field of data communication has made information transmission much easier. But this kind of advancement has opened many possibilities of data being snooped. So, day-by-day maintaining of data security is becoming an inseparable part of computing and communication. In this report, we’ve got explored techniques that blend cryptography and steganography together. Steganography may be a specialty of science to manage and conceal a chunk of important information inside image, audio, video, or text documents. Steganography may be a method and study of composing a secret communication specified only the source and also the targeted beneficiary will realize the concealed information. the information concealed or covered process starts with the steganography method by identifying a network canopy and redundant parts, i.e. only permitted persons would be able to change without affecting the standard of that medium. The encoding method generates a Stego medium by substituting these redundant bits with the concealed message content. In this report, various approaches for information hiding using both cryptography and steganography is proposed keeping in mind two considerations-size of the encrypted object and degree of security. Here, signature image, text, audio information is kept hidden into a cover image using the private key of sender and receiver, which extracts the data from stego image employing a public key. This approach is often used for message authentication, message integrity, and non-repudiation purpose.

«Cloud» diplomacy as a trend in the era of a pandemic: the experience of Italy

2020 became a turning point for many spheres of life, and diplomatic activity was no exception. In the conditions of «closed» borders, diplomatic offi cers had to look for new forms of interaction. The result of such searches was the phenomenon of «cloud» diplomacy, as one of the subspecies of digital diplomacy. As the analysis of the conducted research has shown, even among diplomats there is no consensus on the digitalization of foreign policy. On the one hand, it allows you to reduce the fi nancial and time costs for «live» meetings and speed up the discussion and resolution of operational issues; on the other hand, such virtual communication does not allow «catching the true mood» of the interlocutor and limits his ability to collect additional information. Based on the study of the information presented on the offi cial websites of the President, the government and the Ministry of Foreign Aff airs for the period from 01.03.2020 to 31.12.2020, we came to the following conclusions: 1) digitalization has fi rmly entered the arsenal of means of implementing foreign policy activities; 2) «cloud» diplomacy allows you to discuss a wide range of topical issues; 3) «cloud» diplomacy has not become a priority tool in the work of diplomats; those. it has a utilitarian character, not a value-semantic one. At the same time, the introduction of digital means of communication into circulation made it possible to more actively involve non-state actors in the process of foreign policy interaction: non-profi t organizations, individuals, etc. In addition, the digitalization process forced offi cial institutions and politicians to actively use social networks in their daily activities as a tool for direct communication with society. Summing up, we note that the isolation regime all over the world has provoked a real «boom» in the fi eld of digital communications, which have become an integral part of international relations in the paradigm of the new «normality».

A dynamic three-path authenticating model for anti-counterfeiting in a single host of CaAl2Si2O8

Luminescent materials are one of the most fascinating candidates for the field of data communication and information security because of their special optical characteristics. Unfortunately, unimodal output of luminescent performance reaches unsatisfied security of anti-counterfeiting. Hence, achieving multicolor, multitemporal, and multimodal luminescence performance simultaneously is still a fascinating target, especially in a single host. Here, multi-model optical output is realized for the multiple emission centers of CaAl2Si2O8 doped with Eu3+/Eu2+ ions. Moreover, a successive defect structure is constructed via the introduction of Nd3+ ions, which enables the thermo-/photon- responded luminescence properties. Herein, an efficient three-path authenticating model that performs a dynamic multiple color response and stimulated-sources dependent emission is accomplished in the CaAl2Si2O8 host matrix. The explored multichannel approach offers a unique insight for designing advanced anti-counterfeiting technology.
