CODE "B": THE COMPUTERIZATION AND DISSEMINATION OF DATA OF WORKERS AND UNIONS AT THE ITAIPU PLANT AFTER 1984

Abstract

The present study describes some alphanumeric codes used by the information communities, which would also be applied as elements for the production of psychosocial information about entities and workers at the Itaipu Binacional Hydroelectric Power Plant, in the second half of the 1980s. The approach is based on the hypothesis that systematic computerization, resulting from the advancement of information technology, would give rise to more complex identification mechanisms, which would replace the traditional protocols previously used for the identification of documents exchanged between information communities in the period prior to 1984. In this sense, analyses were carried out of several documents produced by the Security and Information Advisory (AESI) of Itaipu Binacional. From the documents accessed at the Itaipu Documentation Center (CDI), in 2014, it was found that the new forms of identification of CADA/SARDI did not exist before the unionization of the workers, starting to be used specifically in the production of data on the new direction of the Civil Construction Union, whose board of directors was mostly composed of workers from the plant. Therefore, this article has as its main objective to present the new elements of identification of entities and people considered investigated, or already investigated, by the repression agency in certain historical moments.
