The book attempts a thorough analysis of the concept of processing personal data in civil trials and when it is considered unlawful, starting with a thorough analysis of electronic communication and online posts as mechanical representations under the Civil Procedure Code, proceeding to the fundamentally important delineation of the concept of public space, and concluding with the finding that it is not always clear in advance when information is public on the internet.

In this context, based on the theoretical and jurisprudential approaches to date, it analyzes when electronic communication and online posts can be used as evidence without violating the principles of personal data protection and what criteria should be considered for characterizing information on the internet as "public" or "private."
