What does "Opt Out" refer to in the context of data sharing?

In the context of data sharing, "Opt Out" refers to the practice where data is shared automatically by default, unless individuals specifically choose to decline or forbid that sharing. This means that if an individual does not take any action to opt out, their data is shared without their explicit consent. Opting out allows individuals to exercise their rights over their personal data by informing the data collector that they do not wish for their information to be shared.

This approach is often contrasted with "Opt In," where individuals must take a proactive step to consent to data sharing before it occurs. Consequently, in systems that use an opt-out model, consent is assumed unless an individual indicates otherwise. Understanding this distinction is vital for privacy professionals as it has implications for compliance with various privacy laws and regulations that govern data sharing practices.
