Cutting through the noise: Explaining differential privacy and why it matters
The IAPP has published an explainer on differential privacy, a mathematical technique designed to let organizations analyze data about groups of people without exposing information about any individual in those groups.
Why this matters: Differential privacy sounds technical, but the idea behind it is simple: you can learn things from a dataset without learning things about the people in it. That matters because most privacy promises today rely on trust. Differential privacy relies on math. If it works as advertised, it limits what even the organization holding your data can extract about you personally. The catch is implementation. Done badly, it offers the label without the protection.
