Data sharing involves the disclosure and transfer of various types of data, including personal identifiers, financial information, behavioral data, location data, biometric and health data, social media and communications, and employment and education data.
Data can be used in a devious way to target individuals, including microtargeting and manipulation, digital stalking and surveillance, price discrimination, denial of opportunities based on shared data, covert harassment and digital policing, reputation attacks, and the creation of data brokers and shadow profiles.
Unethical use of data can involve creating psychological profiles to manipulate beliefs or behavior, real-time tracking of movements and habits, showing different pricing based on personal data, denying coverage or services based on health or behavioral data, digitally targeting and discrediting individuals, undermining reputations through data leaks or smearing, and the buying and selling of data for profiling and manipulation.
