Personal data refers to any information that can be used to identify an individual, such as their name, address, phone number, or email. This type of data is crucial for businesses and organizations to provide personalized services and maintain customer relationships. However, it also raises significant privacy concerns, as unauthorized access or misuse of personal data can lead to identity theft and other security issues. In today's digital age, personal data is often collected through various means, including online forms, social media, and mobile applications. Individuals must be aware of how their data is used and take steps to protect their privacy, such as using strong passwords and being cautious about sharing information online.
