09:30 The ethics of mass surveillance

Professor Rogaway, a cryptographer and computer scientist from the University of California argues that mass surveillance is abuse prone, anti democratic and is likely to engender a dystopian future. He believes cryptographers and computer scientists like himself must have a stronger sense of social responsibility.

He is speaking at the Asiacrypt Conference tomorrow and says:

"The Snowden revelations have provided a glimpse into a new political reality: the existence of global systems for mass surveillance. This threatens democracy and violates fundamental human rights. Yet the technology is the handiwork of computer scientists like me. How did this happen? Why is there not a stronger sense of social responsibility among scientists and engineers? I will explore such questions, drawing on my experience as a cryptographer and my years teaching a course on ethics to computer scientists and engineers".

10:05 The Political Origins of Banking Crises - Why do banks go bust?

Financial Economics Professor Stephen Haber argues that banking crises are not the product of 'unforeseen shocks', but rather of politics, and we get the banking systems that our political systems allow. This is why American banks go bust so often, (the US has had 12 systemic banking crises since 1840), while Canada and Australia have had none.

Stephen Haber has been described as "one of Stanford's most distinguished teachers" as he has been awarded every teaching prize offered at the American university currently ranked third in the world by Times Higher Education. His current research focuses on three areas: the creation of regulatory barriers to entry in finance; the economic and political consequences of holdup problems created by different systems of agricultural production; and the comparative development of patent systems. He is a regular consultant to the World Bank .

He recently co-authored, 'Fragile by Design: The Political Origins of Banking Crises and Scarce Credit' with Dr Charles Calomiris of Columbia Business School.
