Shafi\\xa0Goldwasser\\xa0is an award-winning mathematician and computer scientist and\\xa0the Director of the Simons Institute for the Theory of Computing at UC Berkeley.\\u202fHer most\\xa0notable work is\\xa0in cryptography and zero knowledge proof. We discuss the promise of cryptography to make our society more secure.\\xa0

Data privacy and you:\\xa0

Cryptography\\xa0is the field that deals with the privacy and correctness of how our\\xa0information is used. It makes\\xa0our 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.\\xa0\\xa0

Algorithmic Fairness and Data Bias:\\xa0

We have an idea that algorithms are fair because they are machine computations. However, algorithms do no account\\xa0for actual individuals, so the data is trained with existing societal norms, which can perpetuate unfairness.\\xa0Data can also be poisoned\\xa0once people figure out what algorithms are used by tweaking the information in order to get the desired outcome.\\xa0

Demand accountability:\\xa0

We must demand that our personal information is only used in ways that can keep our identity private. There are already collaborative platforms using various encryption methods that are effective for governments and companies to use.\\xa0\\u201cIf companies get into trouble because of fiascos having to do with private data you don\'t just blindly continue supporting them.\\u201d\\xa0
