The advancements in internet and 5G communication technologies enormously use images as a crucial element for effective digital communication. Most of the digital devices support image communication as a prominent way of communication in digital Era. Most of the unauthorized access of digital Era communications leads to serious issues in digital data or digital image communications. Hence, Image Security in digital communication becomes an egress area of research in Digital Era. This paper is to design and implement an algorithm with a 96 bits cryptographic system. The result analysis carries out in this paper on input images and presents the comparative analysis of our proposed algorithm with the standard algorithms through standard performance evaluation metrics.

Digital communication technologies are modifying how social movements communicate internally and externally and the way participants are organized and mobilized. This transformation calls for a rethinking of how we conceive of and analyze them. Scholars cannot be content with studying the digital and the physical or the online and the offline separately, but must explore the imbrication between these aspects by studying how the elements of social movements combine in a political “ensemble,” an ecosystem, or an action texture, defining the possibilities and limits of collective action. This chapter proposes a qualitative methodology combining analysis of digital media with observations of events and interviews with participants to develop a holistic account of collective action. This methodology is best positioned to capture the changing nature and meaning of protest action in a digital era, producing a “thick account” of the relationship between digital politics and everyday life.

Significant restrictions on movement outside the home due to the global COVID-19 pandemic have intensified the importance of everyday digital technologies for communicating remotely with intimate others. In this article, we draw on findings from a home-based video ethnography project in Sydney to identify the ways that digital devices and software served to support and enhance intimacy and sociality in this period of crisis and isolation. Digital communication technologies had an increased presence in people’s domestic lives during lockdown. For many people, video calling software had become especially important, allowing them to achieve greater closeness and connection with their friends and family in enacting both everyday routines and special events. These findings surface the digital and non-digital materialities of sociality and intimacy, and the capacities opened by people’s improvisation with the affordances of home-based communication technologies at a time of extended physical isolation.

Abstract. In the post-pandemic era, coronaviruses will forge a long-term coexistence with humanity, and the fight against the pandemic will become the normal. With international social isolation and limited physical space for communication during the COVID-19 pandemic, the digital communication of cultural heritage based on internet technology has not only proven the importance and necessity of cultural heritage digitalization, but will also greatly accelerate the digital transformation that has already begun. In the post-pandemic era, the accumulation of rich digital data on cultural heritage will form the basis for further cultural communication. However, the collection of digital data is not the final link in this digital chain. Effectively leveraging the advantages of the digital technology – which spreads rapidly and has a broad audience as well as vivid information presentation – to integrate and digitally process the existing and emerging cultural heritage data will continuously combine the cultural heritage with new communication technologies. We should use diversified media platforms to achieve further breakthroughs in the communication model, present the digital communication content of the cultural heritage showing the characteristics of the times, and form real and virtual interaction of cultural heritage in a converged media environment, in order to further ease interpersonal isolation and even space-time constraints brought about by the pandemic, reconstruct the communication ecology of cultural heritage, and inherit and utilize the precious wealth left to humanity by history.

For most professionals to succeed in the current job market, they need some entrepreneurial skills (ES). This study aimed to describe and systematize these skills, considering the current globalization and digital transformation phenomena. The documental analysis and the critical reflection on the collected data allowed us to identify the socio-economic and socio-cultural reasons for the relevance of this problem. Consequently, to elaborate a frame of reference intended to be adequate to the needs of the professionals of the current global and digital era. The results pointed to a tripartite ES model—to be open to novelty, to create solutions to emerging problems, and to communicate effectively—which integrates the following skills: Creativity and innovation, the spirit of initiative, self-efficacy and resilience, strategic planning, and evaluation, resolution of problems and decision-making, transformational leadership, clear and visual communication, teamwork and networking, and digital communication. In the continuation of this study, an ES scale will be created and validated according to this model, which will make it possible to measure the degree of development of these competencies.

A method to design and implement digital communication platform was in introduced in this paper. The platform based on software radio method can change modulation method conveniently without the change of hardware system because it used FPGA and DSP to do modulation and signal process. The QPSK modulation and demodulation was implemented in the platform to test this platform.

Youth are coming of age in a digital era and learning and exercising citizenship in fundamentally different ways compared to previous generations. Around the globe, a monumental generational rupture is taking place that is being facilitated—not driven in some inevitable and teleological process—by new media and communication technologies. The bulk of research and theorizing on generations in the digital age has come out of North America and Europe; but to fully understand the rise of an active generation requires a more inclusive global lens, one that reaches to societies where high proportions of educated youth live under conditions of political repression and economic exclusion. The Middle East and North Africa (MENA), characterized by authoritarian regimes, surging youth populations, and escalating rates of both youth connectivity and unemployment, provides an ideal vantage point to understand generations and power in the digital age. Building toward this larger perspective, this article probes how Egyptian youth have been learning citizenship, forming a generational consciousness, and actively engaging in politics in the digital age. Author Linda Herrera asks how members of this generation who have been able to trigger revolt might collectively shape the kind of sustained democratic societies to which they aspire. This inquiry is informed theoretically by the sociology of generations and methodologically by biographical research with Egyptian youth.

ample efforts have been taken in restaurant sector to intrigue the dining experience. Several information and communication technologies have been adopted earlier such as PDA; wireless communication technologies etc.These technologies provide a simple but powerful infrastructure. This paper highlights the limitations of the existing technologies and proposed the E-CONVERSE, which focuses on low cost touch-screen development to enhance the dining experience. In this paper we discuss the design and implementation of a low cost, customizable touch screen. To ensure the security of the system some security strategies are discussed. Basic level testing reveals that proposed system has potential for practical implementation and can overcome several drawbacks of existing system.


We live in a digital world or digital era. Hence, People will argue that not only do information communication technologies (ICTs) make e-health possible but rather that it is an innovation advance whose time has come. Notwithstanding, e-health while hoping to create well needed improvement in health care, it is rife with certain challenges which are not limited to e-health literacy. However, this paper looks specifically at e-health literacy. The paper, in particular overviews e-health while addressing the impacts of key contextual factors that impacts e-health and e-health literacy regarding the propensity to adopt and use e-health in LEDCs.
