<p>The technological advancements and a qualitative improvement in the field of artificial intelligence and deep learning leads to the creation of realistic-looking but phoney digital content known as deepfakes .These manipulated videos can quickly be shared via social media to spread fake news or disinformation which not only impacts those who are deceived it also harms social media sites by diminishing faith.These deepfake videos cannot be checked since there are no regulatory mechanisms in place .As a result these untrustworthy outlets will post whatever they wish causing confusion in society in some ways.Current solutions are unable to provide digital media history tracing and authentication it is essential to develop successful methods for detecting deepfake video as a result it is necessary to determine the source or origin of such deepfake footage.That’s why we are implementing blockchain techniques to trace back and determine the origin of digital media blockchain techniques helps in the effective recognition of deepfake video and calculating the trust factor of user.</p>

Digital content is content in various formats, whether written, image, video, audio or combination so that it can be read, displayed or played by a computer and easily sent or hared through digital media. Digital content has abundant benefits, especially in the field of promotion. Where when a place of business or a body wants to introduce a product or service that is owned, it definitely requires content such as images as a promotional media. However, if you have to distribute posters to everyone you meet, it is not in line with current technological advancements because you are still using a conventional process. Therefore, to overcome this problem, social media can be used to process digital content easily and quickly. In this study, there are 3 (three) problems that will be overcome by 2 (two) methods, and 3 (three) solutions are produced. The advantage of digital content in social media is that it can be accessed anytime and anywhere, so it is concluded that the use of digital content in social media is able to overcome problems and is a creativepreneur effort found in the promotion system of a journal publisher.   Keywords—Digital Content, Creativepreneur, ATT Journal, Social Media

At the fringes of the platform economy exists another web that evokes an earlier era of Internet culture. Its anarchic subculture celebrates a form of play based based on dissimulation. This subculture sets itself against the authenticity injunction of the current mode of capitalist accumulation (Zuboff). We can imagine this as a mask culture that celebrates disguise in distinction to the face culture as embodied by Facebook’s “real name” policy (de Zeeuw and Tuters). Often thriving in the anonymous milieus of web forums, this carnivalesque subculture can be highly reactionary. Indeed, this dissimulative identity play has been increasingly weaponized in the service of alt-right metapolitics (Hawley).Within the deep vernacular web of forums and imageboards like 4chan, users play by a set of rules and laws that they see as inherent to online interaction as such. Poe’s Law, for example, states that “without a clear indicator of the author's intent, it is impossible to create a parody of extreme views so obviously exaggerated that it cannot be mistaken by some readers for a sincere expression of the parodied views”. When these “rule sets” are enacted by a massive angry white teenage male demographic, the “weapons of the geek” (Coleman) are transformed into “toxic technoculture” (Massanari).In light of an array of recent predicaments in digital culture that trace back to this part of the web or have been anticipated by it, this special issue looks to host a conversation on the material practices, (sub)cultural logics and web-historical roots of this deep vernacular web and the significance of dissimulation therein. How do such forms of deceptive “epistemological” play figure in digital media environments where deception is the norm —  where, as the saying goes, everyone knows that “the internet is serious business” (which is to say that it is not). And how in turn is this supposed culture of play challenged by those who’ve only known the web through social media?Julia DeCook’s article in this issue addresses the imbrication of subcultural “lulz” and dissimulative trolling practices with the emergent alt-right movement, arguing that this new online confluence  has produced its own kind of ironic political aesthetic. She does by situating the latter in the more encompassing historical dynamic of an aestheticization of politics associated with fascism by Walter Benjamin and others.Having a similar focus but deploying more empirical digital methods, Sal Hagen’s contribution sets out to explore dissimulative and extremist online groups as found on spaces like 4chan/pol/, advocating for an “anti-structuralist” and “demystifying” approach to researching online subcultures and vernaculars. As a case study and proof of concept of this methodology, the article looks at the dissemination and changing contexts of the use of the word “trump” on 4chan/pol/ between 2015 and 2018.Moving from the unsavory depths of anonymous forums like 4chan and 8chan, the article by Lucie Chateau looks at the dissimulative and ironic practices of meme culture in general, and the subgenre of depression memes on Instagram and other platforms, in particular. In different and often ambiguous ways, the article demonstrates, depression memes and their ironic self-subversion undermine the “happiness effect” and injunction to perform your authentic self online that is paradigmatic for social media platforms like Facebook and Instagram. In this sense, depression meme subculture still moves in the orbit of the early Web’s playful and ironic mask cultures.Finally, the contribution by Joanna Zienkiewicz looks at the lesser known platform Pixelcanvas as a battleground and playfield for antagonistic political identities, defying the wisdom, mostly proffered by the alt-right, that “the left can’t meme”. Rather than fragmented, hypersensitive, or humourless, as online leftist identity politics has lately been criticized for by Angela Nagle and others, leftist engagement on Pixelcanvas deploys similar transgressive and dissimulative tactics as the alt-right, but without the reactionary and fetishized vision that characterises the latter.In conclusion, we offer this collection as a kind of meditation on the role of dissimulative identity play in the fractured post-centrist landscape of contemporary politics, as well as a invitation to think about the troll as a contemporary term by which "our understanding of the cybernetic Enemy Other becomes the basis on which we understand ourselves" (Gallison).ReferencesColeman, Gabriella.

In 2016, Buzzfeed announced the creation of Pero Like, a Facebook page and YouTube channel that would “look at the myriad identities under the ‘Latinx umbrella,’” including “[B]laxicans in LA, Tejanos in Corpus Christi, Cubans in Miami (and their abuelitas), and everyone who’s been told they don’t ‘look Latina.’” Pero Like followed the footsteps of mitú, a new media multi-channel network created in 2012 to target younger, bicultural Latinx audiences who are avid internet users and overlooked by legacy media. This article analyzes how Latina millennial digital content creators negotiate, mediate, and contest Latinidad through social media entertainment. It focuses on four of the most popular Latina creators featured on mitú and Pero Like: Jenny Lorenzo, Kat Lazo, Julissa Calderon, and Maya Murillo. In doing so, the article explores how these creators articulate the politics of Latinx millenniality through a focus on cultural specificity, panethnicity, generational differences, language practices, race and racism, and beauty standards.

The chapter offers a theoretical overview and understanding on issues regarding the way technological disruption transforms old habits and practices in newsrooms leading to innovative storytelling that transcends time and space. The emergence of social media as a main news source, the extensive use of mobile platforms and the advent of complex technologies such as virtual reality (VR) and artificial intelligence (AI) are paving the way for new forms of journalism that are shaping the future of the industry. In this context, this chapter defines and adequately describes the term digital media while, at the same time it sheds light on new forms of journalism that arise from the vast outspread of ‘smart technology' such as conversational journalism, data journalism, drone journalism, network journalism, robot journalism, selfie journalism, slow journalism, and virtual reality journalism.

‘Trolls for Trump’, virtual rape, fake news — social media discourse, including forms of virtual and real violence, has become a formidable, yet elusive, political force. What characterizes online vitriol? How do we understand the narratives generated, and also address their real-world — even life-and-death— impact? How can hatred, bullying, and dehumanization on social media platforms be addressed and countered in a post-truth world? Violence and Trolling on Social Media: History, Affect, and Effects of Online Vitriol unpacks discourses, metaphors, dynamics, and framing on social media, in order to begin to answer these questions. Written for and by cultural and media studies scholars, journalists, political philosophers, digital communication professionals, activists and advocates, this book connects theoretical approaches from cultural and media studies with practical challenges and experiences ‘from the field’, providing insight into a rough media landscape.

AbstractThe ubiquity of social media and their deep integration in the contemporary society has granted new ways to interact, exchange information, form groups, or earn money—all on a scale never seen before. Those possibilities paired with the widespread popularity contribute to the level of impact that social media display. Unfortunately, the benefits brought by them come at a cost. Social Media can be employed by various entities to spread disinformation—so called ‘Fake News’, either to make a profit or influence the behaviour of the society. To reduce the impact and spread of Fake News, a diverse array of countermeasures were devised. These include linguistic-based approaches, which often utilise Natural Language Processing (NLP) and Deep Learning (DL). However, as the latest advancements in the Artificial Intelligence (AI) domain show, the model’s high performance is no longer enough. The explainability of the system’s decision is equally crucial in real-life scenarios. Therefore, the objective of this paper is to present a novel explainability approach in BERT-based fake news detectors. This approach does not require extensive changes to the system and can be attached as an extension for operating detectors. For this purposes, two Explainable Artificial Intelligence (xAI) techniques, Local Interpretable Model-Agnostic Explanations (LIME) and Anchors, will be used and evaluated on fake news data, i.e., short pieces of text forming tweets or headlines. This focus of this paper is on the explainability approach for fake news detectors, as the detectors themselves were part of previous works of the authors.

The transformation of printed media into digital environment and the extensive use of social media have changed the concept of media literacy and people’s habit of consuming news. While this faster, easier, and comparatively cheaper opportunity offers convenience in terms of people's access to information, it comes with a certain significant problem: Fake News. Due to the free production and consumption of large amounts of data, fact-checking systems powered by human efforts are not enough to question the credibility of the information provided, or to prevent its rapid dissemination like a virus. Libraries, known as sources of trusted information for ages, are facing with the problem because of this difficulty. Considering that libraries are undergoing digitisation processes all over the world and providing digital media to their users, it is very likely that unchecked digital content will be served by world’s libraries. The solution is to develop automated mechanisms that can check the credibility of digital content served in libraries without manual validation. For this purpose, we developed an automated fake news detection system based on the Turkish digital news content. Our approach can be modified for any other language if there is labelled training material. The developed model can be integrated into libraries’ digital systems to label served news content as potentially fake whenever necessary, preventing uncontrolled falsehood dissemination via libraries.

Cybersafety has been a mainstay of digital education since computers arrived in classrooms in the mid 1990s. Whether schools encourage students to be ‘cybersmart’ (Australia), ‘netsafe’ (New Zealand) or to be aware of ‘cybersecurity strategies’ (Mexico and Chile) most now devote a relatively large amount of time and money to teaching young people how to ‘stay safe’ online. In this article, we argue that it is time for schools to move beyond the cybersafety discourse to encourage students to think more critically about the digital media they use. Reporting on the digital practices of 276 pre-teens aged 7-12 years in Australia and Uruguay, we contend that the everyday digital challenges young people face are now beyond the scope of most cybersafety programs. Our findings highlight that many of the issues pre-teens are negotiating call for more nuanced and sustained educational programs that support the development of critical social media literacies. In particular, with the proliferation of mass user platforms and artificial intelligence, there is a need for schools to educate students around managing and protecting their personal data. The article concludes with a discussion of the digital learning required for young people in an increasingly datafied society.
