Due to the technological development and huge infiltration of the internet, there is an increasing global interest - public and private context - in dealing and manipulating personal data. Thus, the need of developing legal instruments to regulate this process has become the central target of the most relevant democracies of the world. Due to the new coming Brazilian Law of General Data Protection (LGPD), this study aims the perception of trust, privacy and their connections with the new LGPD, regarding designers and users of digital products/services point of view. A consistent bibliographic review upon recent studies, concepts and legislations related to trust and privacy was used to develop and sustain theoretical basis to apply exploratory interviews, interactive groupworks and digital forms. Through the analysis of the collected data was possible to acknowledge that designers and users considered that a reciprocal relationship is based on trust and privacy is one of the main trust builders. Also, the boundaries between both concepts, trust and privacy, are not easily perceived, as well as the materialization of laws related to the digital environment. This is the scenario of a large field for future researches to promote the creation of tools and processes that will insert privacy into the digital world, increasing the trust perception, and to create law instruments for the implementation of the LGPD in the digital context.
