This article aimed to map the academic production in the area of privacy in Big Data, for the Administration domain, raising the state of the art on the subject and some research opportunities from the gaps in the academic literature. Privacy is a question still open and increasingly threatened by the ubiquitous effect of data-generating devices such as mobile phones, sensors and computers, and new analytical techniques such as Big Data. The extensive bibliometric survey of academic production on the subject was carried out in the main reference databases and analysis of content allied to text mining, using R language. The results pointed not only to areas of concentration and research topics but also new alternatives of research in the area.
