Secret Digital Image Sharing Using Natural Image Based VSS Scheme
International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 Secret Digital Image Sharing Using Natural Image Based VSS Scheme Pinky .V M. Tech Student, Dept. of Computer Science & Engineering Mount Zion College of Engineering, Pathanamthitta, Kerala, India Abstract: Visual cryptography is a technique of sharing secret images. This technique encrypts a secret image into number of shares. Combining these shares generates the original image and it can be directly recognized by the human visual system. Visual Secret Sharing scheme is a method of distributing and sharing the secret image amongst a set of users. In conventional visual secret sharing scheme, the shares May holding the security parameters for protecting the secret image but it will leads to suffering the problem of transmission risk. This is the main problem in conventional VSS scheme. To solve this problem here introduce a new scheme of secret digital image sharing via natural image based VSS scheme. In this proposed scheme the shares are encrypted by using the strong AES encryption technique after that this encrypted share is embedded into the natural image. For recovering the original image, it is necessary to decrypt the encrypted share. This method not only reduces the transmission risk problem but also enhance the security of the secret image. Keywords: Visual Cryptography, Visual Secret Sharing Scheme, Transmission Risk Problem, Natural Image based VSS scheme, Encryption/Decryption technique. 1. Introduction photographs. In the proposed scheme diverse media is used for sharing digital images.

Advertising Content and Consumer Engagement on Social Media: Evidence from Facebook Abstract We describe the effect of social media advertising content on customer engagement using data from Facebook. We content-code 106,316 Facebook messages across 782 companies, using a combination of Amazon Mechanical Turk and natural language processing algorithms. We use this data set to study the association of various kinds of social media marketing content with user engagement—defined as Likes, comments, shares, and click-throughs—with the messages. We find that inclusion of widely used content related to brand personality—like humor and emotion—is associated with higher levels of consumer engagement (Likes, comments, shares) with a message. We find that directly informative content—like mentions of price and deals—is associated with lower levels of engagement when included in messages in isolation, but higher engagement levels when provided in combination with brand personality–related attributes. -
Image-Based Abuse, Non-Consensual Pornography, Revenge Porn: a Study of Criminalization and Crime Prevention in Australia and England & Wales

Image-Based Abuse, Non-Consensual Pornography, Revenge Porn: A Study of Criminalization and Crime Prevention in Australia and England & Wales Majid Yar1 University of Hull, United Kingdom Jacqueline Drew2 Griffith Criminology Institute, Australia Abstract Distribution of nude, intimate and sexualized images of individuals without consent and against the wishes of those individuals whose image has been captured, is of growing concern across the world. Moving from the conceptualization of ‘revenge porn’ in the early 2000’s, through to our more sophisticated understanding of the issues of “image-based abuse” and “non-consensual pornography” this paper considers the broad context of these crimes. The paper draws on the concepts of online misogyny, gender-based victimization, and “toxic masculinity”. The progress towards criminalization of such online abuse, with reference to the recent introduction of new laws in England & Wales and Australia is examined. This shift from voluntary to statutory regulation, and from civil to criminal law remedies has been coupled with new crime prevention and control initiatives that seek to encourage reporting leading to prosecution and educate users and empower victims. -

Narcissism and Social Media Use: a Meta-Analytic Review
Psychology of Popular Media Culture © 2016 American Psychological Association 2018, Vol. 7, No. 3, 308–327 2160-4134/18/$12.00 http://dx.doi.org/10.1037/ppm0000137 Narcissism and Social Media Use: A Meta-Analytic Review Jessica L. McCain and W. Keith Campbell University of Georgia The relationship between narcissism and social media use has been a topic of study since the advent of the first social media websites. In the present manuscript, the authors review the literature published to date on the topic and outline 2 potential models to explain the pattern of findings. Data from 62 samples of published and unpublished research (N ϭ 13,430) are meta-analyzed with respect to the relationships between grandiose and vulnerable narcissism and (a) time spent on social media, (b) frequency of status updates/tweets on social media, (c) number of friends/followers on social media, and (d) frequency of posting pictures of self or selfies on social media. Findings suggest that grandiose narcissism is positively related to all 4 indices (rs ϭ .11–.20), although culture and social media platform significantly moderated the results. Vul- nerable narcissism was not significantly related to social media use (rs ϭ .05–.42), although smaller samples make these effects less certain. Limitations of the current literature and recommendations for future research are discussed.

America Through Street Photography
From the Instructor Sarah wrote this piece for my section of the Genre and Audience WR X cluster. Students had undertaken semester-long research projects and, in the final assignment for the course, were asked to reimagine their academic arguments for a public audience. Deciding to write in the style of The New Republic, which is, in the publication’s own words, “tailored for smart, curi- ous, socially aware readers.” Sarah’s focus on street photography brings her research on classic American images to a non-expert audience with diverse professional and disciplinary perspectives, appealing to their interests in history and the arts while tapping into contemporary culture. — Gwen Kordonowy WR 150: The American Road 135 From the Writer When I enrolled in an experimental writing class entitled “The American Road,” I assumed that the semester would be filled with discussions about the physical American road, its attractions, and its place in American history. While the physical road was an important subject in the class, I learned that this “American Road” was expansive beyond its physical limi- tations, able to encompass topics as broad and abstract as social progress, popular television shows, and, in my case, photography. I ultimately chose to investigate the works of two American street photographers, Robert Frank and Lee Friedlander, whose approaches to photography reveal much about life in America and what it means to be an American. While both photographers frequently feature the road in their pictures, I chose to focus more on the people and culture found alongside it and how they represent America. -

Implementation on Social Media Platforms
Implementation on Social Media Platforms Overview The Eko Video Player is whitelisted for the Twitter and Facebook environments. When end viewers share an Eko video to one of these services, they essentially embed the Eko Video Player onto their timeline. Depending on the service (i.e. Facebook or Twitter), the end viewer’s platform, and whether the post is promoted (on Facebook only), the Eko Video Player will either play inline within the social media feed, in a new tab within the social media space, or in a new browser tab. Support for the Eko Video Player within these services is made possible by meta tags that are added to the HTML of the site where the video is hosted. These meta tags enable a Facebook Preview and Twitter Card to display in the feed when the video site url is shared on these services. The cards link directly to the interactive video object, enable playback, and specify the sharing copy for the content (provided by the partner). Direct links to videos hosted by Eko automatically include the meta tags to enable inline playback on shared posts, but for videos embedded outside of helloeko.com on a client’s website, the meta tags will need to be added to the website in the <head> part of the page’s HTML and tested. Facebook Open Graph Meta Tags When someone shares a video project hosted on your site to Facebook, Facebook’s crawler will scrape the HTML of the URL that is shared. On a regular HTML page this content is basic and may be incorrect, because the scraper has to guess which content is important, and which is not. -
The New Urban Success: How Culture Pays
The New Urban Success: How Culture Pays DESISLAVA HRISTOVA, Cambridge University, Cambridge, UK LUCA MARIA AIELLO, Nokia Bell Labs, Cambridge, UK DANIELE QUERCIA, Nokia Bell Labs, Cambridge, UK Urban economists have put forward the idea that cities that are culturally interesting tend to attract “the creative class” and, as a result, end up being economically successful. Yet it is still unclear how economic and cultural dynamics mutually influence each other. By contrast, that has been extensively studied inthecase of individuals. Over decades, the French sociologist Pierre Bourdieu showed that people’s success and their positions in society mainly depend on how much they can spend (their economic capital) and what their interests are (their cultural capital). For the first time, we adapt Bourdieu’s framework to the city context. We operationalize a neighborhood’s cultural capital in terms of the cultural interests that pictures geo-referenced 27 in the neighborhood tend to express. This is made possible by the mining of what users of the photo-sharing site of Flickr have posted in the cities of London and New York over 5 years. In so doing, we are able to show that economic capital alone does not explain urban development. The combination of cultural capital and economic capital, instead, is more indicative of neighborhood growth in terms of house prices and improvements of socio-economic conditions. Culture pays, but only up to a point as it comes with one of the most vexing urban challenges: that of gentrification.

Cultural History Cultural history brings to life a past time and place. In this search, cultural historians study beliefs and ideas, much as What is Cultural History? historians do. In addition to the writings of intellectual elites, they consider the notions sometimes unwritten of the less privileged and less educated. These are reflected in the products of deliberately artistic culture, but also include the objects and experiences of everyday life, such as clothing or cuisine. In this sense, our instincts, thoughts, and acts have an ancestry which cultural history can illuminate and examine critically. Historians of culture at Yale study all these aspects of the past in their global interconnectedness, and explore how they relate to our many understandings of our varied presents. Cultural history is an effort to inhabit the minds of the people of different worlds. This journey is, like great literature, thrilling in itself. It is also invaluable for rethinking our own historical moment. Like the air we breathe, the cultural context that shapes our understanding of the world is often invisible for those who are surrounded by it; cultural history What is Cultural History? us to take a step back, and recognize that some of what we take for granted is remarkable, and that some of what we have thought immutable and What is Cultural History? is contingent and open to change.
