Description: User data sharing refers to the practice of allowing access to an individual’s personal and behavioral data by other individuals or systems. This concept is fundamental in the digital age, where information has become a valuable resource. Data sharing can include information such as purchasing preferences, browsing history, geographical location, and demographic data. The relevance of this practice lies in its ability to enhance service personalization, optimize user experience, and facilitate informed decision-making for both businesses and consumers. However, it also raises significant issues related to privacy and data protection, as unauthorized access or misuse of this information can lead to privacy violations and exposure to security risks. Therefore, it is essential for organizations to implement appropriate measures to ensure that data sharing is conducted ethically and securely, respecting user rights and complying with relevant regulations.
