In this thesis examines the transformations in the digital environment circumscribed to the intersections between new marketing practices and the protection of the consumer-data subjects. The main drive is the strengthening of information as an important asset in contemporary consumer society. From the perspective of surveillance capitalism, it analyzes the central phenomena that contributes to the establishment of a structure of stimuli and controls that permeate, imperceptibly to the consumer s eyes, his journey. It is verified that digital advertising, especially the so-called behavioral advertising, directed according to the consumer s profile, despite being target of criticism by the doctrine and of interest by the legislation, is only the visible part of an architecture of choices permeated by dark patterns that hinder consumer protection in the digital environment. In this scenario, the research investigates the sufficiency of personal data protection mechanisms, as well as the existence of a new and universal consumer vulnerability. Which is the digital vulnerability that gives rise as well to a universal state of consumer hyposufficiency before commercial practices in the digital environment.
