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!

That said, this Bill of Rights is not a document “carved in stone” (or written on paper). It is a blog post, and it is intended to spur conversation and debate, which will naturally lead to tweaks of the language. So, let’s get the dialogue going and get as many of the major stakeholders on board as we can! A Bill of Rights for Users of the Social Web We publicly assert that all users of the social web are entitled to certain fundamental rights, specifically: Ownership of their own personal information, including: • their own profile data • the list of people they are connected to • the activity stream of content they create; • Control of whether and how such personal information is shared with others; and • Freedom to grant persistent access to their personal information to trusted external sites. -

Federated Systems
Federated Systems Jeremy Rubin [email protected] December 9, 2015 Abstract Federation is an amazingly powerful tool in a system designer’s tool belt. This work provides a unifying definition for federated. In abbrevia- tion: a system is federated when there are multiple providers of an iden- tical (or nearly identical), interoperable service. The federated paradigm o↵ers much improved fault tolerance, liberty, and privacy over centralized alternatives. The federated paradigm applies to all sorts of systems, from governmental to web services. However, this paradigm seems to be unsus- tainable, either devolving into centralized systems or being outpaced by them. In this paper, I will delve into multiple examples of federated sys- tems, exploring their successes and failures, as well as delving into what caused the decay of these systems. In reflection, I will also provide sev- eral suggestions on how system developers might harden their use of this paradigm. 1 Contents 1 Introduction: 3 2 Defining Federation: 5 2.1 Governmental Federations . 6 2.2 ComputerScience .......................... 8 2.2.1 Simple Sharded Database . 8 2.2.2 Federated Byzantine Agreement . 8 2.2.3 Federated Cryptography . 9 2.3 FederatedIdentity .......................... 9 2.4 TheDefinition ............................ 10 3 Case Studies 11 3.1 E-Mail................................. 12 3.2 Blog.................................. 14 3.3 XMPP................................. 15 3.4 DNS.................................. 16 3.5 Security Assertion Markup Language . 17 3.6 McDonald’s . 18 3.7 Social Networks . 18 3.7.1 Failures in Centralized Social Networks . 18 3.7.2 Hope in Federation? . 20 4 Conclusion 21 4.1 The Federated System Designer’s Handbook . -

Network Working Group C. Kalt Request for Comments: 2813 April 2000 Updates: 1459 Category: Informational Internet Relay Chat: Server Protocol Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2000). All Rights Reserved. Abstract While based on the client-server model, the IRC (Internet Relay Chat) protocol allows servers to connect to each other effectively forming a network. This document defines the protocol used by servers to talk to each other. It was originally a superset of the client protocol but has evolved differently. First formally documented in May 1993 as part of RFC 1459 [IRC], most of the changes brought since then can be found in this document as development was focused on making the protocol scale better. Better scalability has allowed existing world-wide networks to keep growing and reach sizes which defy the old specification.

Leadership and Legacy
Leadership and Legacy Upstanding in a Time of Crisis: Leadership Toward Solutions and Embracing Opportunities Presentation by Ross C. “Rocky” Anderson Former Salt Lake City Mayor and President, High Road for Human Rights ICLEI Local Action Summit Albuquerque Convention Center Albuquerque, New Mexico May 15, 2008 Leadership. People who will stand up. Never before has our nation, and our world, been in greater need of competent, principled, knowledgeable, far-sighted, non-partisan, inspiring leadership. And never before have we been in such need of what Samantha Power calls “upstanders” – people who will stand up and fight effectively and honestly for solutions, rather than cower in fear of rocking the boat. Our nation invaded and attacked a country that posed absolutely no security threat to us – all on the basis of a gargantuan fraud. And it did so without a plan as to what we would do after the invasion. (Sounds like our nation’s energy policy!). At a time when the US is investing only $5 billion per year in research and development of alternative energy sources, we are pouring $12 billion per month into the big, black hole of disastrous military occupation in Iraq – creating more hostility, more hatred, more terrorism every day we are viewed by the Muslim world as an occupying force. It’s bad enough that we have such a dismal lack of leadership in the White House, but what do the so-called “leaders” in Congress do? These traitors to our Constitution and the rule of law snipe, they complain, they play the worst sorts of politics, but they don’t stand up. -

A Tool for Internet Chatroom Surveillance
A Tool for Internet Chatroom Surveillance Ahmet C¸amtepe, Mukkai S. Krishnamoorthy, and B¨ulent Yener ? Department of Computer Science, RPI, Troy, NY 12180, USA. {camtes, moorthy, yener}@cs.rpi.edu Abstract. Internet chatrooms are common means of interaction and communications, and they carry valuable information about formal or ad-hoc formation of groups with diverse objectives. This work presents a fully automated surveillance system for data collection and analysis in Internet chatrooms. The system has two components: First, it has an eavesdropping tool which collects statistics on individual (chatter) and chatroom behavior. This data can be used to profile a chatroom and its chatters. Second, it has a computational discovery algorithm based on Singular Value Decomposition (SVD) to locate hidden communities and communication patterns within a chatroom. The eavesdropping tool is used for fine tuning the SVD-based discovery algorithm which can be deployed in real-time and requires no semantic information processing. The evaluation of the system on real data shows that (i) statistical prop- erties of different chatrooms vary significantly, thus profiling is possible, (ii) SVD-based algorithm has up to 70-80% accuracy to discover groups of chatters. 1 Introduction and Background Internet chatrooms provide for an interactive and public forum of communica- tion for participants with diverse objectives. Two properties of chatrooms make them particularly vulnerable for exploitation by malicious parties. First, the real identity of participants are decoupled from their chatroom nicknames. Second, multiple threads of communication can co-exists concurrently. Although human- monitoring of each chatroom to determine who-is-chatting-with-whom is possible, it is very time consuming hence not scalable. -
