For a person to be considered "identified" requires that he/she be distinguished from other members of that community while in a community.

Personal data has gained importance with the importance of the Big Data concept. It has become mandatory to take precautions especially for the protection of personal data. With the developing age, easy access to information includes positive developments as well as major risks.

Personal data refers to all kinds of information regarding an identified or identifiable natural person. In this context, not only the information that provides a definitive diagnosis such as the name, surname, date of birth and place of birth of the individual, but also information about the physical, familial, economic, social and other characteristics of the person is personal data. The fact that a person is specific or identifiable means making that person identifiable by associating the existing data with a real person in any way.

For a person to be considered “identified” requires that he/she be distinguished from other members of that community while in a community. Accordingly, the phrase “identifiable” will mean that it is possible to determine the identity of the person even though the identity of the person has not been determined yet. As can be understood, the lower threshold for the fulfilment of this element is to be “identifiable”.
