Authentication and integrity of smartphone videos through multimedia container structure analysis

Nowadays, mobile devices have become the natural substitute for the digital camera, as they capture everyday situations easily and quickly, encouraging users to express themselves through images and videos. These videos can be shared across different platforms exposing them to any kind of intentional manipulation by criminals who are aware of the weaknesses of forensic techniques to accuse an innocent person or exonerate a guilty person in a judicial process. Commonly, manufacturers do not comply 100% with the specifications of the standards for the creation of videos. Also, videos shared on social networks, and instant messaging applications go through filtering and compression processes to reduce their size, facilitate their transfer, and optimize storage on their platforms. The omission of specifications and results of transformations carried out by the platforms embed a features pattern in the multimedia container of the videos. These patterns make it possible to distinguish the brand of the device that generated the video, social network, and instant messaging application that was used for the transfer. Research in recent years has focused on the analysis of AVI containers and tiny video datasets. This work presents a novel technique to detect possible attacks against MP4, MOV, and 3GP format videos that affect their integrity and authenticity. The method is based on the analysis of the structure of video containers generated by mobile devices and their behavior when shared through social networks, instant messaging applications, or manipulated by editing programs. The objectives of the proposal are to verify the integrity of videos, identify the source of acquisition and distinguish between original and manipulated videos.

An Analysis of The Contents of Da'wah Attaki in You Tube Media with The Title of "The Most Beautiful Love" in The Perspective of Religious Moderation

The emergence of radical community organizations has lately threatened religious moderation, which has become the spiritual feature of the majority of Muslims in Indonesia. You Tube media plays an important role in both moderate and radical preaching spreading. This article will examine Hanan Attaki's proselytization in the video published on April 17, 2018 in You Tube entitled "The Most Beautiful Love." Hanan Attakiis the founder of the "Youth Hijrah" society that has a "Youth Hijrah" You Tube account with many student supporters. The research question is how is the Hanan Attaki video message from You Tube entitled "The Most Beautiful Love" to convey the ethics of creating love for teenagers and whether the message is from a moderate or radical view. Yusuf Qardlawi, a mujtahid cleric in this century, is the notion of moderation used. Thisresearch utilizes a technique of qualitative content analysis, a technique for systematically, objectively and visibly evaluating communication to the message being observed and being nonreactive.

KAJIAN METODE METODE STEGANOGRAFI PADA DOMAIN SPASIAL

This paper contains a review of the spatial domain steganographic literature. The purpose of this paper is to provide knowledge about techniques or methods that exist in the spatial domain of steganography. Steganography is the science or technique for hiding secret messages in other messages so that the existence of the secret message cannot be accessed by others who do not have authority. There are several popular spatial domains of steganographic techniques, namely LSB (Least Significant Bit), which is mapping secret message bits in the rightmost bit (LSB) of each color pixel and PVD (Pixel Value Differencing) which in this method offers a larger message storage capacity , with better image quality compared to other methods in the spatial domain. Because privacy issues continue to develop along with various digital communication technologies, and increasingly strong security threats, steganography can play a role in society to maintain the confidentiality of both picture, voice and video messages. For this reason it is important for us to be aware of steganographic technology and its implications.

Strong health messages increase audience brain coupling

Mass media messaging is central for health communication. The success of these efforts, however, depends on whether health messages resonate with their target audiences. Here, we used electroencephalography (EEG) to capture brain responses of young adults - an important target group for alcohol prevention - while they viewed real-life video messages of varying perceived message effectiveness about risky alcohol use. We found that strong messages, which were rated to be more effective, prompted enhanced inter-subject correlation (ISC). In further analyses, we linked ISC to subsequent drinking behavior change and used time-resolved EEG-ISC to model functional neuroimaging data (fMRI) of an independent audience. The EEG measure was not only related to sensory-perceptual brain regions, but also to regions previously related to successful messaging, i.e., cortical midline regions and the insula. The findings suggest EEG-ISC as a marker for audience engagement and effectiveness of naturalistic health messages, which could quantify the impact of mass communication within the brains of small target audiences.

Your Cheating Cognitions: Young Women’s Responses to Television Messages about Infidelity

The current study examined how exposure to a depiction of sexual infidelity on television influenced women’s responses to hypothetical infidelity. In addition, we examined three individual factors as moderators for these effects: experience with infidelity, infidelity concern, and loyalty concern. In a laboratory experiment, young women were exposed to a media narrative featuring either a romantic relationship, the same relationship but with one partner engaging in sex outside the relationship, or a control narrative before completing measures of reactions to hypothetical relationship transgressions. Results indicated that women who had a cheating partner and exhibited high levels of concern about infidelity reported a lower tolerance for infidelity following exposure to a television narrative featuring infidelity.

Media Images of Anorexia: Effects of Moderate vs. Extreme Anorexia-Related Messages on Young Women.

The aim of the study was to examine which type of anorexia-related messages have been presented on television and how they have affected young women in Israel. An empirical study was performed in two parts: (1) Anorexia-related stories that had aired on the news editions of commercial TV channels in Israel were categorized by code page. (2) A random sample was conducted among 291 women, aged 13-35. Every interviewee was requested to complete one online questionnaire that differed in its attached video message: an extreme or a moderate anorexia-related message. 71.4% of the tv-stories featured a young anorexic woman suffering from extreme underweight. Moreover, the extreme message resulted in higher reaction than the moderate message and less agreement with the message (rejecting anorexia and preferring that it be eradicated). Theoretical and practical implications of the findings will be discussed.

The commendable man: an anthropological experience of self-slimming based on health TV journalism

This article presents the results of an ethnographic research about food, a theme that has gained prominence in Brazilian TV. The author of this work followed feeding tips from the Bem Estar program, Rede Globo; slimmed 25 kg in four months, and noted the sensations he had and the reactions of others. The study considers that Brazilian TV propagates the idea of lean body as "normal" and as a model to be followed. The work uses observant participation. It is an ethnographic research technique in which the researcher not only observes the phenomenon, but also participates in it (in this case, noting changes in the body itself). The manuscript uses an interdisciplinary technique to associate themes from Anthropology to Social Communication. He concludes that the television message in favor of thinness transforms the one who slims into a commendable man.

Queue size estimation of nodes in a heterogeneous ocean network with multiple priority traffic

Ocean network is a heterogeneous wireless network of fishing vessels at sea to provide internet over sea. The types of messages exchanged between fishing vessels include emergency data, normal data, voice and video messages. As the connectivity is intermittent, it is necessary to select the most appropriate message from the transmission queue for forwarding. This paper focuses on designing a queuing model with multiple priorities to estimate the queue size of each type of message in a node. Solving the steady state equations gives the number of emergency packets, data packets, audio packets and video packets waiting in the node to be transmitted. Hence the message dissemination algorithm can select the appropriate queue for transmitting the message to maximise the available resources with fairness.

Nonverbal Content and Swift Trust: An Experiment on Digital Communication

We experimentally study the effect of the mode of digital communication on the emergence of swift trust in a principal-agent relationship. We consider three modes of communication that differ in the capacity to transmit nonverbal content: plain text, audio, and video. Communication is pre-play, one-way, and unrestricted, but its verbal content is homogenized across treatments. Overall, both audio and video messages have a positive (and similar) effect on trust as compared to plain text; however, the magnitude of these effects depends on the verbal content of agent's message (promise to act trustworthily vs. no such promise). In all conditions, we observe a positive effect of the agent's promise on the principal's trust. We also report that trust in female principals is sensitive to the availability of nonverbal cues about interaction partners.

A Texting Intervention in Latino Families to Reduce ED Use: A Randomized Trial.

Latino children in immigrant families experience health care disparities. Text messaging interventions for this population may address disparities. The objective of this study was to evaluate the impact of a Spanish-language text messaging intervention on infant emergency department use and well care and vaccine adherence. The Salud al Día intervention, an educational video and interactive text messages throughout the child's first year of life, was evaluated via randomized controlled trial conducted in an urban, academic pediatric primary care practice from February 2016 to December 2017. Inclusion criteria were publicly insured singleton infant <2 months of age; parent age >18, with Spanish as the preferred health care language; and at least 1 household cellular phone. Primary outcomes were abstracted from the electronic medical record at age 15 months. Intention-to-treat analyses were used. A total of 157 parent-child dyads were randomly assigned to Salud al Día (n = 79) or control groups (n = 78). Among all participants, mean parent age was 29.3 years (SD: 6.2 years), mean years in the United States was 7.3 (SD: 5.3 years), and 87% of parents had limited or marginal health literacy. The incidence rate ratio for emergency department use for the control versus intervention group was 1.48 (95% confidence interval: 1.04-2.12). A greater proportion of intervention infants received 2 flu vaccine doses compared with controls (81% vs 67%; P = .04). This Spanish-language text messaging intervention reduced emergency department use and increased flu vaccine receipt among a population at high risk for health care disparities. Tailored text message interventions are a promising method for addressing disparities.

Mobile marketing influence on football fan behaviour: the case of FC Persepolis

The purpose of this study is to identify the effect of mobile marketing (photo, video, and short message service, SMS or text messaging) in promoting one of the best Iranian football clubs, Persepolis, fans' behaviour in the 2018-2019 season. We collected data on the attitudinal loyalty, behavioural loyalty, and mobile marketing use of the fans attending a home game. We utilised structural equation modelling (SEM) to analyse the data. The findings indicate that mobile marketing has a positive effect on fans' attitudinal and behavioural loyalties. Also, attitudinal loyalty has a positive impact on the behavioural loyalty of the Iran Persepolis Football Club fans. We recommend that the managers of the Pro League clubs such as Persepolis prepare the infrastructure for the implementation of fan supporting systems for their organisations. Furthermore, they should employ media experts and professionals to enhance the relationship between their brand, customers, and delivery of information. This is among the first mobile marketing studies about football fans behaviour in the Middle East.

Connecting with Nature in the Digital Age: Intentions of Adolescents in California Urban Areas

Automated devices dominate the daily experience for most people in the United States, and for many, nature offers a respite ripe with well-documented emotional, psychological, and physical benefits. However, opportunities with and access to open spaces can be limited by structural barriers that often create limits to engagement by people living in urban areas. A first stage of this project initiated with listening sessions and workshops with youth in urban and rural settings in southern and central California as a means of crafting effective marketing strategies designed by youth to engage young people of color with nature and open spaces. The second stage, reported here, was implemented to examine the effects of race/ethnicity and social media video messaging on Theory of Planned Behavior (TPB) dimensions. Using a quasi-experimental design, panels of urban youth aged 12-16 in four California cities participated in an online panel survey. Participants were randomly assigned to one of three themed message groups generated from the content themes developed by youth during the workshops (escape and unplug, connect with family and friends, or discover and adventure) or a control group. The questionnaire included 11 items related to the TPB. Separate 4x4 ANOVAs with race/ethnicity and the treatments/control group as the independent variables and TPB dimensions as the dependent variables revealed an interaction effect for one perceived behavioral control item. There were also significant differences by race/ethnicity on all four TPB dimensions. Mean scores of the respondents who watched one of the three videos were higher than the control group for all 11 TPB items measured. TPB item scores among White and Black respondents were typically higher than scores for Asian and Latinx respondents. Results of a hierarchical regression analysis with race/ethnicity, treatments/control group, perceived behavioral control, attitudes, and social norms as the independent variables and behavioral intentions as the dependent variable suggested that attitudes and social norms were the strongest predictors of behavioral intentions. The results add significant value in the practical application of the intersection between automated devices and social media marketing for engaging underrepresented groups in the digital age.

Governing Body of the Church in Wales

The April meeting was held while the Anglican Consultative Council was meeting in Hong Kong, and the Governing Body received a video message from Dr Heather Payne and the Ven Mary Stallard, its two representatives. In his presidential address to the September meeting, the Archbishop of Wales spoke of the challenges facing the Church and said that those who challenged the Church, asking sometimes uncomfortable questions, deserved to be taken seriously. He also highlighted some of the initiatives that the Church in Wales was undertaking as part of the acknowledgement that the status quo for ministry in Wales was unlikely to meet the needs of the province in the decades ahead.

Conceptual Metaphor as a Means of Terrorist Suggestion (on the Material of the Islamic State Video Messages)

Manipulative verbal influence is an immanent feature of modern international communication. Successful realization of the suggestive aspect allows the speaker to exert influence on the recipient’s worldview and ingrain certain ideological attitudes in their mind. This situation is characteristic of various types of discourse: political, advertising and media. However, the most dangerous for political stability and safety is utilization of persuasive linguistic devices by extremist groups and terrorist organizations. Thus, research in this field has become extremely relevant. The article presents linguistic analysis of such manifestations of destructive manipulation in the Islamic State (IS) speech, found in their official video messages. The analysis was carried out on the material of the official IS video messages, obtained through the selective sampling method on the video hosting website YouTube. Within the framework of the research we distinguish, classify and subject to a thorough linguistic analysis of conceptual metaphors which are used by the terrorists. The data obtained enables us to make a conclusion regarding the key role of conceptual metaphor in realization of the IS speaker’s communicative intention, which presupposes attracting the recipient’s attention to their activities and creating a radicalized ideological attitude in the minds of the audience. Furthermore, we prove that the metaphor is deliberately used by the terrorists to successfully fulfill their pragmatic intention, which involves manipulating the recipient. The provisions developed as part of the study and the results of the analysis can be further applied in modelling the mechanisms to confront and counteract terrorist suggestion in cyberspace and mass media.

PENERAPAN METODE MODULUS FUNCTION (MF) UNTUK PENYISIPAN PESAN PADA CITRA DIGITAL

Steganography is the science and art of hiding (embedded) information by inserting secret messages in other messages. Steganography in the field of information technology is highly developed, namely for digital devices. Information or messages that can be hidden varies, as can messages that are embedded objects. Variations of messages that are normally subject to insertion objects are text messages, picture messages, audio messages, and video messages. The steganography method used is the Modulus Function (MF) method. This method can insert more messages into pixels that have high contrast values. The research conducted is applying the Modulus Function (MF) method for inserting messages into image files. Based on the test results, it can be concluded that by using the Modulus Function (MF) method, the capacity of the image to insert a message is smaller than the image size, the processing time in this method is quite fast, the image quality after inserting a message has good quality, but this method is also still good. has disadvantages, because it is not resistant to manipulation and in some images are still detected by the matlab application.Keywords: Steganography, Implementation, Modulus Function (MF), Image file.

Echo hiding method for video file message security

Sending secret message need an algorithm that can protect message to receiver without knowing by other and keep the originality of message. Previous research, encoding secret message in video inserted in frame while audio secret message inserted in bit audio. it makes it easier for someone to detect the presence of a message. In this paper, try to encode the secret message at video file to encode in audio. Audio separated from video in order to encode secret message in audio. Echo Hiding method used in encode secret message to audio process. Testing use Bit Error Rate (BER) method to analysis modification in audio and Normalized Correlation (NC) analysis authentic the secret message. Based on the experiment, the results obtained were NC values (0.98-1) and BER values (0-3.12). based on the results obtained by the method we can insert messages better than the previous method with the addition of noise elimination in audio.

Characteristics of a Nationwide Voluntary Antibiotic Resistance Awareness Campaign in India; Future Paths and Pointers for Resource Limited Settings/Low and Middle Income Countries.

Antibiotic resistance has reached alarming proportions globally, prompting the World Health Organization to advise nations to take up antibiotic awareness campaigns. Several campaigns have been taken up worldwide, mostly by governments. The government of India asked manufacturers to append a ‘redline’ to packages of antibiotics as identification marks and conducted a campaign to inform the general public about it and appropriate antibiotic use. We investigated whether an antibiotic resistance awareness campaign could be organized voluntarily in India and determined the characteristics of the voluntarily organized campaign by administering a questionnaire to the coordinators, who participated in organizing the voluntary campaign India. The campaign characteristics were: multiple electro–physical pedagogical and participatory techniques were used, 49 physical events were organized in various parts of India that included lectures, posters, booklet/pamphlet distribution, audio and video messages, competitions, and mass contact rallies along with broadcast of messages in 11 local languages using community radio stations (CRS) spread all over India. The median values for campaign events were: expenditure—3000 Indian Rupees/day (US$~47), time for planning—1 day, program spread—4 days, program time—4 h, direct and indirect reach of the message—respectively 250 and 500 persons/event. A 2 min play entitled ‘Take antibiotics as prescribed by the doctor’ was broadcast 10 times/day for 5 days on CRS with listener reach of ~5 million persons. More than 85%ofcoordinators thought that the campaign created adequate awareness about appropriate antibiotic use and antibiotic resistance. The voluntary campaign has implications for resource limited settings/low and middle income countries.

WhatsApp messaging improves communication in an oral and maxillofacial surgery team

ObjectiveSmartphones have become very popular among oral and maxillofacial surgeons. WhatsApp is an application that enables users to send voice, text, and multimedia messages using the group communication feature. The purpose of this study was to evaluate the efficiency of WhatsApp messaging as a mode of consultation within an oral and maxillofacial surgery team. Materials and methodsA retrospective study on WhatsApp group conversations amongst oral and maxillofacial surgeons was performed between July 2015 and July 2016. A WhatsApp group consisting of senior and junior surgeons was created, and many consultations were recorded. Seven hundred fifty-six consultations were included in the study. In this study, the arrival and response times of messages, types of cases, timing of consultation’s end, consultant locations, contents of multimedia messages, and the categories/types of messages were evaluated. During consultations, some cases were discussed with text messages via WhatsApp, and some cases with voice and image messages via WhatsApp, with or without WhatsApp text messages. In addition, several cases were discussed with video messages via WhatsApp. Thus, a total of 1747 messages reflecting four different message types were included in this study: 754 (43%) were text messages, 752 (43%) were photographic images, 213 (12%) were videos, and 28 (nearly 2%) were voice messages. ResultsThe most frequent consultations concerned impacted teeth (n = 363, 48.01%). Most consultations were resolved using WhatsApp (n = 306, 64.4%), and consultants were often not in the hospital during these consultations (n = 411, 54.3%). Most messages sent by consultants were conclusive (n = 306, 74.4%). ConclusionWe conclude that WhatsApp is a simple, free, and practical application, which allows efficient consultation when consultants are not in the hospital.

Political Factors Affecting Parents’ Perceptions on Televised Polio Messages in Sindh, Pakistan: A Critical Investigation

Television messages are one of the essential means to disseminate polio messages in the prevention of infectious diseases. However, little is known about the hegemony of political actors specifically government in power over televised health content and its impact on people’s perceptions to adopt or reject a health attitude, particularly in developing countries. Theoretically, Bandura in his social cognitive theory (1997) has examined the change in mind-sets through observational learning, media and social surroundings. However, his research lacks to underline state dominancy over people’s health decisions with reference to political leadership. This study fills the gap by critically investigating political factors that obstruct Pakistani television channels to disseminate productive and informative polio messages, for boosting self-efficacy among lower middle class Jamshoro parents, thus encouraging them to vaccinate their children against polio in Sindh province of Pakistan. The methodological approach employs critical paradigm with qualitative investigation through in-depth interviews. Low level of awareness, less credibility of television channels and political hegemony over health messages contributed and enlarged self-efficacy to collective efficacy of political actors during findings of this research study as a new domain in social cognitive theory. In addition, this research sheds light by critically analysing the elements of corruption, unaccountability and lack of transparency involved in ineffective televised polio messages in developing nations as Pakistan, opening a space for policy makers and television officials for a positive health change in designing health awareness campaigns. Keywords: Television messages, parents’ perceptions, polio, political hegemony, collective efficacy.
