The Chilean Congress is discussing a bill that will modify the current leg- islation on personal data protection. The General Data Protection Regulation of the European Union inspires the bill, but in some matters the legislator has decided to innovate by means of modifications that move it away from the European model. This work focuses on those aspects related to compliance with the standard of protection of personal data that was originally proposed to be achieved. This paper aims to contribute to the legislative discussion and to give an account of some of the main tools the European legislator has sought to provide data subjects for the protection of their right to informational self-determination.
