    Social networks are the platform for the users to get connected with other social network users based on their interest and life styles. Existing social networks have millions of users and the data generated by them are huge and it is difficult to differentiate the real users and the fake users. Hence a trust worthy system is recommended for differentiating the real and fake users. Social networking enables users to send friend requests, upload photos and tag their friends and even suggest them the web links based on the interest of the users. The friends recommended, the photos tagged and web links suggested may be a malware or an untrusted activity. Users on social networks are authorised by providing the personal data. This personal raw data is available to all other users online and there is no protection or methods to secure this data from unknown users. Hence to provide a trustworthy system and to enable real users activities a review on different methods to achieve trustworthy social networking systems are examined in this paper

    The Future of Connection : Serendipity and Control in Interpersonal Communication Tools

    Get PDF
    This foresight project explored the contemporary trends and tensions inherent in people's experiences with and using interpersonal communication tools. A standard foresight process was overlaid with an experiential lens in order to provide technology designers with useful insights. The outcomes of this project include four tools intended for designers of interpersonal communication applications. These tools include a map of experiential tensions, a landscape of contemporary behaviour, a set of four future scenarios and implications of each, and finally a set of ten reflection questions intended to provoke critical thought about the choices designers make about the balance between serendipity and control in interpersonal communication tools

    An overview on user profiling in online social networks

    Advances in Online Social Networks is creating huge data day in and out providing lot of opportunities to its users to express their interest and opinion. Due to the popularity and exposure of social networks, many intruders are using this platform for illegal purposes. Identifying such users is challenging and requires digging huge knowledge out of the data being flown in the social media. This work gives an insight to profile users in online social networks. User Profiles are established based on the behavioral patterns, correlations and activities of the user analyzed from the aggregated data using techniques like clustering, behavioral analysis, content analysis and face detection. Depending on application and purpose, the mechanism used in profiling users varies. Further study on other mechanisms used in profiling users is under the scope of future endeavors

    The Excited Utterance Paradox

    Based on nothing more than John Henry Wigmore’s personal belief that a witness under the throes of excitement is unable to fabricate an untruthful statement, the excited utterance exception allows parties to present out-of-court statements to the jury or judge without any of the safeguards the judicial system uses to promote honest and accurate testimony. This Article collects and examines much of the scientific evidence bearing on Wigmore’s premise and identifies two paradoxical conclusions that undermine the exception. First, the premise itself is unfounded; science absolutely does not support the notion that a witness is incapable of lying while emotionally agitated. But, there is a second phenomenon at work that counteracts the premise (were it valid); witnesses under extreme emotional stress are unreliable observers and reporters of the events causing the stress. Thus, in the unlikely event that an occurrence was sufficiently stressful to impede the ability to lie, the stress would also interfere with the ability to perceive and describe the occurrence reliably. Based on this paradox, this Article concludes that the excited utterance exception is both broken and irreparable, and therefore recommends abandoning the excited utterance exception altogether

    vi, 342 p. : ill. ; 25 cmLibro ElectrónicoOn January 9, 2007, Steve Jobs introduced the iPhone to an eager audience crammed into San Francisco’s Moscone Center.1 A beautiful and brilliantly engineered device, the iPhone blended three products into one: an iPod, with the highest-quality screen Apple had ever produced; a phone, with cleverly integrated functionality, such as voicemail that came wrapped as separately accessible messages; and a device to access the Internet, with a smart and elegant browser, and with built-in map, weather, stock, and e-mail capabilities. It was a technical and design triumph for Jobs, bringing the company into a market with an extraordinary potential for growth, and pushing the industry to a new level of competition in ways to connect us to each other and to the Web.Includes bibliographical references (p. 249-328) and index Acceso restringido a miembros del Consorcio de Bibliotecas Universitarias de Andalucía Electronic reproduction.

    Improving User Involvement Through Live Collaborative Creation

    Creating an artifact - such as writing a book, developing software, or performing a piece of music - is often limited to those with domain-specific experience or training. As a consequence, effectively involving non-expert end users in such creative processes is challenging. This work explores how computational systems can facilitate collaboration, communication, and participation in the context of involving users in the process of creating artifacts while mitigating the challenges inherent to such processes. In particular, the interactive systems presented in this work support live collaborative creation, in which artifact users collaboratively participate in the artifact creation process with creators in real time. In the systems that I have created, I explored liveness, the extent to which the process of creating artifacts and the state of the artifacts are immediately and continuously perceptible, for applications such as programming, writing, music performance, and UI design. Liveness helps preserve natural expressivity, supports real-time communication, and facilitates participation in the creative process. Live collaboration is beneficial for users and creators alike: making the process of creation visible encourages users to engage in the process and better understand the final artifact. Additionally, creators can receive immediate feedback in a continuous, closed loop with users. Through these interactive systems, non-expert participants help create such artifacts as GUI prototypes, software, and musical performances. This dissertation explores three topics: (1) the challenges inherent to collaborative creation in live settings, and computational tools that address them; (2) methods for reducing the barriers of entry to live collaboration; and (3) approaches to preserving liveness in the creative process, affording creators more expressivity in making artifacts and affording users access to information traditionally only available in real-time processes. In this work, I showed that enabling collaborative, expressive, and live interactions in computational systems allow the broader population to take part in various creative practices.PHDComputer Science & EngineeringUniversity of Michigan, Horace H.
