There’s no question the data that organizations collect and share about users is valuable. Whether it’s content created by users or metadata about users, that information could be used to streamline healthcare or corporate operations, prevent fraud, or increase marketing opportunities. Data sharing by ad networks or data brokers is commonplace, yet users have virtually no visibility or control over it. At the same time, in situations where user data sharing among organizations could benefit society, it’s limited by a lack of technologies and standards to support user privacy.
