Promising Privacy Tech

July 08, 2024

We’re generating a ridiculous amount of data every day. Much of it is highly personal and that’s dangerous. But there are actually several Privacy Enhancing Technologies that may allow us to use this personal data to improve our collective quality of life without ruining the privacy of the data subjects. I’ll be discussing these PETs with Irene Knapp who spent five years working in the privacy department at Google. I will also spend a good bit of time asking them about what it’s like working at Google and get some insights about the company’s approach to privacy from the inside. (Spoiler: it’s not good.)
