Future Hindsight

Shafi Goldwasser is an award-winning mathematician and computer scientist and the Director of the Simons Institute for the Theory of Computing at UC Berkeley. Her most notable work is in cryptography and zero knowledge proof. We discuss the promise of cryptography to make our society more secure.  Data privacy and you:  Cryptography is the field that deals with the privacy and correctness of how our information is used. It makes our data more secure, with a range of tools such as encryption, authentication, and verification. Every time we are online, we need to be vigilant about what private information we share and with whom. We should use the tools of cryptography and be careful about giving permissions for apps to access our data.   Algorithmic Fairness and Data Bias:  We have an idea that algorithms are fair because they are machine computations. However, algorithms do no account for actual individuals, so the data is trained with existing societal norms, which can perpetuate unfairness. Data can also be
