DETECTING BOTS in INTERNET CHAT by SRITI KUMAR Under The
DETECTING BOTS IN INTERNET CHAT by SRITI KUMAR (Under the Direction of Kang Li) ABSTRACT Internet chat is a real-time communication tool that allows on-line users to communicate via text in virtual spaces, called chat rooms or channels. The abuse of Internet chat by bots also known as chat bots/chatterbots poses a serious threat to the users and quality of service. Chat bots target popular chat networks to distribute spam and malware. We first collect data from a large commercial chat network and then conduct a series of analysis. While analyzing the data, different patterns were detected which represented different bot behaviors. Based on the analysis on the dataset, we proposed a classification system with three main components (1) content- based classifiers (2) machine learning classifier (3) communicator. All three components of the system complement each other in detecting bots. Evaluation of the system has shown some measured success in detecting bots in both log-based dataset and in live chat rooms. INDEX WORDS: Yahoo!

Expectation of Privacy in Internet Communications
Fourth Amendment Aspects of Internet Communications and Technology Dennis Nicewander Assistant State Attorney 17th Judicial Circuit Ft. Lauderdale, Florida The emergence of Internet technology has revolutionized the world of communication and information sharing. Unfortunately, criminals have seized this opportunity to enhance the efficiency and productivity of their criminal pursuits. The task ahead of law enforcement is daunting, to say the least. New forms of technology emerge before we are able to master the old ones. The most significant legal issue to arise in this struggle to make order out of chaos is the application of the Fourth Amendment to these emerging technologies. If our economy is going to continue to grow at the rapid pace promised by Internet technology, we must find a way to balance our citizens‟ right to privacy with the necessity of establishing law and order in this new frontier. As our culture and legal system suffer the growing pains of radical change, it is responsibility of prosecutors to work together with law enforcement to strike a balance between effective police work and privacy rights afforded by the Fourth Amendment. Understanding the role of “reasonable expectation of privacy” is critical to this role. Since most information placed on the Internet is designed for mass distribution, a reasonable expectation of privacy will not apply in the majority of cases. The purpose of this paper is to provide basic guidance and case law concerning this issue as it relates to some of the most common forms Internet technology. The topics will be divided into the following categories: General Privacy Cases Email Chatrooms Peer-to-Peer Internet Service Provider Records Websites Bulletin Boards University Usage Logs Text Messages General Privacy Cases Katz v. -

Abstract Introduction Methodology
Kajetan Hinner (2000): Statistics of major IRC networks: methods and summary of user count. M/C: A Journal of Media and Culture 3(4). <originally: http://www.api-network.com/mc/0008/count.html> now: http://www.media-culture.org.au/0008/count.html - Actual figures and updates: www.hinner.com/ircstat/ Abstract The article explains a successful approach to monitor the major worldwide Internet Relay Chat (IRC) networks. It introduces a new research tool capable of producing detailed and accurate statistics of IRC network’s user count. Several obsolete methods are discussed before the still ongoing Socip.perl program is explained. Finally some IRC statistics are described, like development of user figures, their maximum count, IRC channel figures, etc. Introduction Internet Relay Chat (IRC) is a text-based service, where people can meet online and chat. All chat is organized in channels which a specific topic, like #usa or #linux. A user can be taking part in several channels when connected to an IRC network. For a long time the only IRC network has been EFnet (Eris-Free Network, named after its server eris.berkeley.edu), founded in 1990. The other three major IRC networks are Undernet (1993), DALnet (1994) and IRCnet, which split off EFnet in June 1996. All persons connecting to an IRC network at one time create that IRC network’s user space. People are constantly signing on and off, the total number of users ever been to a specific IRC network could be called social space of that IRC network. It is obvious, that the IRC network’s social space by far outnumbers its user space. -
Restoring in All Situations

Users As Co-Designers of Software-Based Media: the Co-Construction of Internet Relay Chat
Users as Co-Designers of Software-Based Media: The Co-Construction of Internet Relay Chat Guillaume Latzko-Toth Université Laval AbsTrAcT While it has become commonplace to present users as co-creators or “produsers” of digital media, their participation is generally considered in terms of content production. The case of Internet Relay Chat (IRC) shows that users can be fully involved in the design process, a co-construction in the sense of Science and Technology Studies (STS): a collective, simultaneous, and mutual construction of actors and artifacts. A case study of the early de - velopment of two IRC networks sheds light on that process and shows that “ordinary users” managed to invite themselves as co-designers of the socio-technical device. The article con - cludes by suggesting that IRC openness to user agency is not an intrinsic property of software- based media and has more to do with its architecture and governance structure. Keywords Digital media; Communication technology; Co-construction; Design process; Ordinary user résumé Il est devenu banal de présenter l’usager comme cocréateur ou « produtilisateur » des médias numériques, mais sa participation est généralement envisagée comme une production de contenus. Le cas d’IRC (Internet Relay Chat) montre que les usagers des médias à support logiciel peuvent s’engager pleinement dans le processus de conception, une co-construction au sens des Science and Technology Studies : une construction collective, simultanée et mutuelle des acteurs et des artefacts. Une étude de cas portant sur le développement de deux réseaux IRC éclaire ce processus et montre que les « usagers ordinaires » sont parvenus à s’inviter comme co-concepteurs du dispositif. -
