Preserving Privacy in Personal Data Processing

Nowadays, the spread of information systems and the operation of service sectors through digital applications such as data mining, data analysis, recommendation systems, and digital marketing have brought the need to store and process large amounts of personal data in the systems of organizations. Although it is beneficial to process these data within the scope of the services provided, it may cause victimization and loss of rights if unauthorized persons take over. Therefore, the protection methods to be applied to these personal data have become a necessity for all organizations. Ensuring privacy during the processing, storage and publishing (sharing) of data is an important concern. In recent years, privacy measures have gained more importance due to national and international regulations for the protection of personal data as well. Consequently, there are certain rules that organizations should follow in their information systems, where large volumes of personal data are processed, stored and shared. In this work, some of the techniques, which are used for preserving privacy while processing personal data, are reviewed.
