The processing of such data may, however, be excluded from the scope of Regulation (EU) 2016/679 if it constitutes the processing of personal data carried out by a natural person in the course of a purely personal or household activity. Nevertheless, even if such exception is not fulfilled, this does not automatically determine the illegality of the processing that did not observe the principles and rules concerning the protection of personal data. In this assessment, legitimate interests are considered and, specifically according to the portuguese law, the safeguard of ‘sensitive data’ is imperative. Recent portuguese case-law indicates that the digital age, which encourages public exposure, raises debate on the permeability of the private sphere boundaries, demonstrating that a purely personal activity involving the processing of personal data could represent an activity whose exercise may be legally preventable.engData protectionProcessing of personal dataPersonal or household activityLegitimate interestsLimits of private lifePortuguese case-lawconference object
