Thank you to this week's sponsor Trail of Bits

Trail of bit recently released a blog post that might be interesting for our listeners who are concerned about privacy. The post is about the concept of 'Safe browsing'. Safe browsing claims to protect users by providing them with something called k-anonymity.

Recent security news suggests that the k-anonymity has failed at protecting user privacy in certain circumstances. This is the topic that Trail of Bits explores in the blog post. Find out more about how k-anonymity works and why it is insufficient here: https://blog.trailofbits.com/2019/10/30/how-safe-browsing-fails-to-protect-user-privacy/
