The objective of this work is to spread academic research on the recent transformations experienced by traditional civil law institutions ––ownership and liability–– within the field of right to privacy. The evolution of the data privacy that belongs to a person is checked. The notion of the right to privacy and its evolution towards a personal data protection right from a comparative law perspective in order to discover the advances of the Italian and the American law. This work also proposes to review the traditional postulates of property and civil liability to find solutions regarding data security as a person’s heritage. And whose infringement causes damage that have to be reviewed from public liability. Additionally, there is the possibility that with the protection of personal data, a way may be opened to protect the right to privacy and achieve a balance between it and the right to the circulation of information. Italian data protection law is a great example. It allows the content of the privacy to shape the privacy regulations, and has specified both preventive and compensatory protection of the damages derived from the infringement of personal data. The comparative look makes it easier to check the valid legislation in Colombia and the current status of a possible compensation for damages due to the violation of personal data. This allows considering the contributions of comparative law to structure a better articulated protection in Colombia.
