Fast-paced technological development of the recent years has resulted in the abuse of personal data and an increasing concern pertaining to privacy issues. To tackle current challenges, the General Data Protection Regulation (GDPR) was introduced in 2018, with the goal of establishing a modern and comprehensive framework for personal data protection in the European Union. GDPR constitutes a relatively complex legal act; therefore, the implementation of its rules presents a considerable challenge for the organisations. In light of this, the organisations clearly need a lot of time, resources and guidelines to coordinate with the GDPR. Hence, a number of organisations have turned to independent experts for help, resulting in considerable expenses. For some, the financial burden is too big, as is the case with the Municipality of Dobrna, the organisation in question. The diploma thesis presents the entire procedure of the reform of the system of personal data protection in correspondence with the GDPR, with the aim of saving time and financial resources of the Municipality of Dobrna. Based on the qualitative analysis, the theoretical part examines the field of personal data protection and determines which new rules are introduced by GDPR in the practical sense. With the help of foreign and domestic literature, the process of coordination with the GDPR was established and the key documents for the successful reform of the system of personal data protection were determined. Based on these findings, the empirical part of the thesis presents the entire procedure of the coordination of the operations of the Municipality of Dobrna with the GDPR, consisting of a number of key activities. However, it is important to recognise, that the personal data protection is a never-ending process, necessitating regular activities such as routine monitoring and rapid reaction to real-time changes in the field of personal data protection.
