It includes all data, including sensitive personal data such as biometric data, health information, and religious or political beliefs. The law sets out data processing principles such as purpose limitation, data minimization, accuracy, storage limitation, privacy, and personal data security.
The principles of personal data protection in Turkey and confidentiality are fundamental principles that must be followed, particularly with regard to the processing and use of personal data. The following principles are based on general data protection regulations and privacy standards accepted worldwide and GDPR in Turkey:
- Principle of lawfulness and fairness: Personal data processing must be done in compliance with a legal basis and the principle of fairness.
- Principle of purpose limitation: Personal data must be collected and used for specific, clear, and legitimate purposes. Collected data should not be used for purposes other than those intended.

By following these steps, you can protect your personal data and control the processing process of data protection in Turkey in compliance with data protection and data privacy in Turkey regulations.
VIOLATION OF PERSONAL DATA PRIVACY
Personal data protection in Turkey can be violated in many situations. For example, a company may be in violation of the KVKK if it collects personal data without the consent of the data subject or fails to implement appropriate security measures to protect the data. Other types of violations include sharing personal data with third parties without consent, failure to respond to a data subject’s access or deletion requests, and excessive retention of personal data.
Personal data protection and privacy can be violated in many different situations. Some examples include:
- Data breaches: Personal data being acquired or disclosed through unauthorized access, alteration, or destruction.
- Fraudulent activity: Personal data being obtained through deceptive or fraudulent activity, such as scams or phishing.
- Misuse of data for processing purposes: Personal data being used for purposes other than those for which it was collected, even if consent was obtained for the original purpose.
- Data security vulnerabilities: Insufficient systems or methods used for processing and storing personal data, or existence of data security vulnerabilities.
- Data loss: Accidental deletion, destruction, or loss of personal data.
- Lack of information and consent: Processing of personal data without adequate information provided about how it is collected, processed, and used or without obtaining consent from the data subject.
In such cases, personal data protection in Turkey and data privacy in Turkey can be compromised and legal sanctions may be required. Therefore, it is important to be careful when processing and protecting personal data under GDPR in Turkey.
LEGAL PROCESS FOR UNAUTHORIZED SHARING OF PERSONAL DATA
When personal data is shared without the consent of the data owner, the affected individual can file a complaint with the Personal Data Protection Authority (KVKK) in Turkey. The Authority has the power to investigate and penalize companies that act in violation of the KVKK regulations. Depending on the severity of the violation, companies can be fined, ordered to stop processing personal data, or even face criminal sanctions. Data owners can also file a compensation claim against companies that violate GDPR in Turkey regulations, seeking compensation for any damages caused by the violation.
In the case of unauthorized sharing of personal data, the legal process works as follows:
- Complaint: If a data owner realizes that their personal data has been shared without consent, they should first file a complaint. The complaint can be made in writing to the data controller or to the KVKK institution or other authorized bodies.
- Investigation: Upon receiving the complaint, the data controller will start an investigation if they acknowledge that the personal data has been shared without consent. The investigation is conducted by KVKK institutions or other authorized bodies.
- Sanction: If the investigation finds that the unauthorized sharing of data has indeed taken place, sanctions can be imposed. These sanctions may include fines, temporary or permanent suspension of the data controller’s activities, revocation of the data controller’s authorization certificate, and other legal sanctions under GDPR in Turkey.
- Compensation: If the data owner has suffered damages as a result of the unauthorized sharing of personal data, they can seek compensation. This compensation can be sought from the data controller or from other liable parties determined by court order.
In conclusion, the unauthorized sharing of personal data is a serious violation that is addressed through legal processes. Data controllers must process data in accordance with the KVKK requirements and must not share data without the consent of data owners. Otherwise, they may face legal sanctions.
