报告摘要：
In the digital age, anonymity is critically important since individuals' lifestyles, habits, whereabouts, and associations can be inferred from their online transactions. Anonymity can help activists and whistleblowers to safely report on abuses and corruption. Unfortunately, anonymity is a double-edged
sword that can be abused. Some users may misbehave under the cover of anonymity, e.g., by defacing web pages on Wikipedia or posting vulgar comments on YouTube. Some people believe decreased privacy is an unavoidable consequence to ensure accountability.
In this talk, we discuss how existing anonymous authentication techniques from the cryptographic community provide various balances among security, anonymity and accountability. We also present some of our recent results.
