Speakers and abstracts

David Chaum: Chaum, LLC

Search, Ads and Everything: Shifting Online Paradigms Again

Abstract: The web has gone through a series of transitions between successive commerce models. The next model promises to be more participatory and egalitarian, more open to competition, and less subject to manipulation — yet more privacy protecting. Some new technologies and approaches to business that may catalyze the transition will be described.

David Chaum

Biography: Widely recognized as the inventor of eCash (electronic cash), he is also known for first proposing cryptographic techniques (including untraceable communication and credential mechanisms) that more generally allow individuals to protect their identity and related information. David has over 50 original publications in the area of cryptography and dozens of patents issued and pending. With Ph.D in Computer Science from Berkeley, he taught at several universities, established one of the leading crypto research groups, and founded DigiCash and the International Association for Cryptologic Research (IACR). Currently he is affiliated with several companies, universities and international projects. David was elected Fellow of the IACR in 2004.

Brian O'Higgins: Chief Technology Officer, Third Brigade Inc.

Mitigating the Current Biggest Security and Privacy Headache — Targeted Attacks on Web Applications

Abstract: Hackers are extremely innovative, and continue to launch new attacks. Recently, the biggest threat has been targeted attacks on vulnerabilities in software that make up web applications. These attacks go through firewalls, and as they are not viruses, they are not picked up by virus scanners. Even intrusion detection technology is not sufficient. A new layer of defence is necessary, and this is intrusion prevention.

This talk will outline various approaches to intrusion prevention, with a discussion on the effectiveness of these approaches.

Brian O'Higgins

Biography: Mr. O'Higgins is seasoned professional in the security industry, and is best known for his role in introducing PKI (Public Key Infrastructure) technology and products to the security landscape. He is also a recognized speaker on IT and Internet security.

Prior to joining Third Brigade as a member of the founding executive team, Mr. O'Higgins was the co-Founder and Chief Technology Officer of Entrust, a leading Internet Security company. While at Entrust he had overall responsibility for the technology vision and direction for the company. He was previously with Nortel where he established the Secure Networks group in 1993, and was instrumental in spinning-out this group as an independent company, Entrust. Prior to this, Mr. O'Higgins was with Bell-Northern Research (BNR) where he was involved in a variety of technology development programs including public key security systems, technology for new telephone products, in-building wireless communications systems and high-performance computing architectures for digital telephone switches.

Mr. O'Higgins' current list of affiliations includes advisory board positions with Defence R&D Canada, Information Technology Association of Canada, Communications and Information Technology Ontario, Algonquin College, and the Armed Forces Communications and Electronics Association. In addition, he currently serves on the boards of Recognia and Fischer International.

Sandeep Krishnamurthy: Associate Professor of E-Commerce and Marketing, University of Washington, Bothell

Michelle's Web-side Story

Abstract: Michelle loves the World Wide Web. She regularly visits many sites to read the news and to check her email. She even goes to to buy her family and friends presents during the holiday season. A professor recently educated her about how much information is collected on the Internet. Michelle was very surprised that operators of Web sites knew when she logged on, how long she was connected, which sites she visited and even knew which software she ran on her computer. Her surprise soon turned to outrage. She wanted to know why these vendors were collecting this information without telling her. She soon realized that there was a privacy policy that she could have read to learn about such matters. She really tried to read the policy. But, after encountering the fifth "hitherto" and the seventh "heretofore", she became quite muddled and confused. She did not know what to think. "Was this a good guy or a bad guy?", she wondered when she visited the next web site. She could not tell and that started to bother her. Michelle then started to ask her friends if they had educated themselves about privacy — most had not. She knew that something had to be done about educating consumers about privacy matters. But, what? (to be continued at the talk.... see you there)

Vie privée et sécurité nationale : les enjeux de la surveillance dans les environnements électroniques

Résumé : Le Canada a ratifié la Convention du Conseil de l'Europe sur le cybercrime. Le ministère fédéral de la Justice propose de modifier les dispositions du Code criminel notamment afin d'accroître les pouvoirs de surveilance des autorités policières dans les environnements électroniques afin, prétend-il, de se conformer à la Convention sur le cybercrime. Cette proposition législative (Lawful Access) présente des menaces sérieuses au droit à la vie privée et à la liberté de «circulation» sur Internet.
