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. -

Helpful Definitions
HELPFUL DEFINITIONS Internet – an immense, global network that connects computers via telephone lines and/or fiber networks to storehouses of electronic information. With only a computer, a modem, a telephone line and a service provider, people from all over the world can communicate and share information with little more than a few keystrokes. Bulletin Board Systems (BBSs) – electronic networks of computers that are connected by a central computer setup and operated by a system administrator or operator and are distinguishable from the internet by their “dial up” accessibility. BBS users link their individual computers to the central BBS computer by a modem which allows them to post messages, read messages left by others, trade information, or hold direct conversations. Access to a BBS can, and often is, privileged and limited to those users who have access privileges granted by the systems operator. Commercial Online Service (COS) – examples of COSs are America Online, Prodigy, CompuServe and Microsoft Network, which provide access to their service for a fee. COSs generally offer limited access to the internet as part of their total service package. Internet Service Provider (ISP) – These services offer direct, full access to the internet at a flat, monthly rate and often provide electronic mail service for their customers. ISPs often provide space on their servers for their customers to maintain World Wide Web (WWW) sites. Not all ISPs are commercial enterprises. Educational, governmental and nonprofit organizations also provide internet access to their members. Public Chat Rooms – created, maintained, listed and monitored by the COS and other public domain systems such as Internet Relay Chat. -
