Until a few years ago, however, Scattered Castles, the database containing security clearance applications for the US Intelligence Community, was not connected to the OPM database. But in 2010, new legislation aiming to eliminate the growing backlog in processing security-clearance applications required that Scattered Castles be merged with the OPM database. The proposed move, which aimed to create a unified system for processing security clearances made sense in terms of eliminating bureaucratic overlap and reducing duplication within the federal apparatus.
But, According to the Daily Beast, US intelligence officials expressed concerns about the merging of the databases as early as 2010. The website said that security experts from the Intelligence Community expressed “concerns related to privacy, security and data ownership” emerging from the impending merge. One official told the Daily Beast that there were fears that the “names, Social Security numbers, and personal information for covert operatives would be exposed to hackers”.
