Personal data refers to any information that can be used to identify an individual, either on its own or in combination with other data. This can include a person’s name, address, date of birth, social security number, email address, phone number, financial information, and even their IP address. Personal data is often collected and processed by organizations for various purposes, such as providing services, conducting market research, or for legal and regulatory compliance. It is important to protect personal data and ensure its confidentiality, as it can be used for identity theft or other malicious purposes if it falls into the wrong hands.
