Recently, the growth of the internet is increased day by day also the digital data such as videos, images and audio availability to the public get increased rapidly. The society required intellectual property protection. To protect the media from other attack intruders and avoid business loss is the requirement of digital media produced. Introducing watermarks can be useful to safeguard copyright. In this review an effort is made to explore various aspects of watermarking, algorithms used, and to carry out a comparative study of these techniques based on their classifications.

Durch den digitalen Medienwandel ist der Begriff der Öffentlichkeit problematisch geworden. Die Debatte fokussiert sich zumeist auf die Frage, ob die sogenannte bürgerliche Öffentlichkeit durch das Internet im Niedergang begriffen ist oder eine Intensivierung und Pluralisierung erfährt. Rudolf Maresch zeichnet die berühmte Untersuchung der Kategorie durch Jürgen Habermas nach und zieht den von ihm konstatierten Strukturwandel der Öffentlichkeit in Zweifel. Dagegen verweist er auf die gouvernementalen und medialen Prozesse, die jede Form von Kommunikation immer schon gesteuert haben. Öffentlichkeit sei daher ein Epiphänomen nicht allein des Zeitungswesens, sondern der bereits vorgängig ergangenen postalischen Herstellung einer allgemeinen Adressierbarkeit von Subjekten. Heute sei Öffentlichkeit innerhalb der auf Novitäts- und Erregungskriterien abstellenden Massenmedien ein mit anderen Angeboten konkurrierendes Konzept. Mercedes Bunz konstatiert ebenfalls eine Ausweitung und Pluralisierung von Öffentlichkeit durch den digitalen Medienwandel, sieht aber die entscheidenden Fragen in der Konzeption und Verteilung von Evaluationswissen und Evaluationsmacht. Nicht mehr die sogenannten Menschen, sondern Algorithmen entscheiden über die Verbreitung und Bewertung von Nachrichten. Diese sind in der Öffentlichkeit – die sie allererst erzeugen – weitgehend verborgen. Einig sind sich die Autoren darin, dass es zu einer Pluralisierung von Öffentlichkeiten gekommen ist, während der Öffentlichkeitsbegriff von Habermas auf eine singuläre Öffentlichkeit abstellt. </br></br>Due to the transformation of digital media, the notion of “publicity” has become problematic. In most cases, the debate is focused on the question whether the internet causes a decline of so-called civic publicity or rather intensifies and pluralizes it. Rudolf Maresch outlines Jürgen Habermas's famous study of this category and challenges his claim concerning its “structural transformation,” referring to the governmental and medial processes which have always already controlled every form of communication. Publicity, he claims, is an epiphenomenon not only of print media, but of a general addressability of subjects, that has been produced previously by postal services. Today, he concludes, publicity is a concept that competes with other offers of mass media, which are all based on criteria of novelty and excitement. Mercedes Bunz also notes the expansion and pluralization of the public sphere due to the change of digital media, but sees the crucial issues in the design and distribution of knowledge and power by evaluation. So-called human beings no longer decide on the dissemination and evaluation of information, but algorithms, which are for the most part concealed from the public sphere that they produce in the first place. Both authors agree that a pluralization of public sphere(s) has taken place, while Habermas's notion of publicity refers to a single public sphere.

The development of the Internet and social media and networks as a media environment and communication channels combined with the specificity of the journalistic profession in the online environment are a factor which contributes to the emergence and proliferation of fake news. The lack of reliable fact checking by the media and the fast news consumption by the public lead to mass disinformation about certain issues or subjects. The current paper examines fake news from several points of view and describes the models of their use – as harmless jokes, as lack of journalistic competence or professionalism and as means of manipulation and intentional misleading of public opinion. The attempts of big media corporations to fight fake news are also described.

The spread of digital media on the internet was very broad, fast, and cannot be monitored in a structured manner about what media has been uploaded and distributed on the internet network. The spread of digital media like this was very difficult to detect whether the media that shared was privately owned or that of others that is re-shared by media theft or digital media piracy. One step to overcome the theft of digital works is to give them a watermark, which is an identity that is placed on top of the work. However, this is still considered unsafe because the identity attached can be cut and manipulated again until it is not visible. In addition, the use of Steganography method to hide messages in an image can still be manipulated by adding messages continuously so that it accumulates and damages the original owner of the image. In this article, the author provides a solution called Digital Watermarking, a step of encrypting the data of the original owner of the work and putting it into the image of his work. This watermark cannot be seen clearly, but actually in the media there is encrypted data with a strong Advanced Encryption Standard (AES) method. As a result, a tool that can improve the security of media owner data by combining the AES and Steganogaphy methods in the formation of new media that cannot be changed anymore. So, when the media is stolen and used by others and has been edited, the owner's personal data can never be changed.

This chapter reviews the relationship between the media and the Umbrella Movement. The mainstream media, aided by digital media outlets and platforms, play the important role of the public monitor in times of major social conflicts, even though the Hong Kong media do so in an environment where partial censorship exists. The impact of digital media in largescale protest movements is similarly multifaceted and contradictory. Digital media empower social protests by promoting oppositional discourses, facilitating mobilization, and contributing to the emergence of connective action. However, they also introduce and exacerbate forces of decentralization that present challenges to movement leaders. Meanwhile, during and after the Umbrella Movement, one can also see how the state has become more proactive in online political communication, thus trying to undermine the oppositional character of the Internet in Hong Kong.

This study shows that digital media increases internet addiction and FoMO due to the impact of digitalization. As digitalization expands day by day and becomes a platform that can be addressed in its needs such as socialization, people's dependence on the internet is also increasing. Currently, digitalization also uses digital citizenship and digital identity as auxiliary elements. Without digital citizenship and digital identity, the impact of digitalization will also decrease. Digital citizenship and digital identity separate people from the normal and physical world and involve them in the digital plane. In this process, internet addiction is exposed due to the need to socialize, and individuals become even more dependent for socializing reasons. FoMO, on the other hand, is another indicator that addiction is growing. FoMO is increasing digital needs as there is a fear of missing out on the processes that are happening. As a result, internet addiction and FoMO are directly proportional to the increase in digital citizenship and digital identity.

AbstractThis article is focusing on the state of research into the extent to which the opportunities for information, communication and participation opened up by the Internet have led to greater mobilisation of the public for political participation. After briefly presenting the diversity of conflicting expectations towards the Internet’s role for the political process, the article discusses the relevance of digital media as a means for mobilising greater and more equal political participation from a liberal-representative perspective on democracy. At the core of the article is a discussion of the last 15 years of research empirically testing the mobilisation hypothesis as well as the theories proposed to explain the observed participation patterns. What becomes dear is that the Internet does indeed slightly increase rates of political participation but with few exceptions those newly mobilised come from parts of the population that are already politically active. At the same time, the explanations still exhibit considerable gaps that remain to be dosed. To this end future research needs to address a number of challenges which are discussed in the final section of the article.

This epilogue comments on the changes within the Polish American community and the Polish-language press during the most recent decades, including the impact of the Internet and social media on the practice of letter-writing. It also poses questions about the legacy and memory of Paryski in Toledo, Ohio, and in Polonia scholarship. Paryski's life and career were based on his intelligence, determination, and energy. He believed that Poles in the United States, as in Poland, must benefit from education, and that education was not necessarily the same as formal schooling. Anybody could embark on the path to self-improvement if they read and wrote. Long before the Internet changed the way we communicate, Paryski and other ethnic editors effectively adopted and practiced the concept of debate within the public sphere in the media. Ameryka-Echo's “Corner for Everybody” was an embodiment of this concept and allowed all to express themselves in their own language and to write what was on their minds.

The presence of mass media in the current era of globalization is nothing special, various kinds of media appear, grow and develop like mushrooms in the rainy season, especially with the internet that allows connections between individuals in this world. The media enter into people's lives and have an influence on one's beliefs, this is in line with the opinion of Jhon Vivian who said that mass media is a facility that carries messages to the public. A person's religious behavior arises because of an internal urge, which then gets an influence from the environment. In subsequent developments, religious behavior is much influenced by factors of religious experience, personality, psychological elements and others. Human life experiences several phases in the level of development of the religious soul in itself, including the children's phase, the adolescent phase, the adult phase, and the advanced phase. Each phase has its own characteristics and uniqueness. One of the formers of religious character in these phases is the mass media. Mass media in the present era is not only a complement but also a part of life. This media has both positive and negative influences on humans.

It is a modern type of technology that empowers virtual and physical artefacts to interact and provide digitized services for each other, and includes the Internet of Things (IoT). But it has some benefits, but raises problems of single point of failure, anonymity, accountability, and data integrity due to the new structured design. Challenges like these stands in the path of the introduction of all the most interesting Internet of Things technologies. Bringing the Internet of Things through the public ledger might fix these issues. Decentralized ledger systems are comprised of blockchain as well as distributed ledgers. The introduction of the Internet of Things (IoT) to the blockchain will offer tremendous advantages. Blockchain integration in this paper offers a detailed exploration of how to combine the IoT technology with the IoT scheme. It is followed by reviewing the basic framework and addressing the problems inherent in the system's integration, explaining the advantages of it, and describing ways in which the blockchain can help to overcome such problems. Blockchain as a Service for IoT can illustrate how different protocol concepts can be applied using different service types on blockchain. After this, there would be an important section about the integration of artificial intelligence (AI) into the Internet of Things (IoT) and blockchain. Finally, potential study avenues will focus on ways of applying the Internet of Things (IoT) with blockchain are suggested. The open issues and challenges of 5G-enabled IoT for blockchain-based Industrial automation are also analyzed in the text.
