Stasi / Facebook / Big Data DAAD Day 17 – Stasi networks and Facebook Social Graph

Similar to how Facebook uses a user’s connections to determine information about them, the Stasi considered all information they could gather about a person in their intelligence campaigns. They incorporated not only the contents of a target’s mail, but information about professional and personal relationships, love affairs, and organizations to which they belonged. (Reinicke, 106)

This attention to not only the contents of a person’s postal communications, but their social connections can be evidenced in this hand-made graphic discovered at the BStU by Julia Angwin. The graphic shows forty-six connections, linking a targeted citizen to other potentially interesting persons (e.g. an aunt), places (e.g. “church”), and meetings (e.g. post, phone). Through whichever means necessary the Stasi made and utilized these connections in order to gain additional insights and institute methods of control.

This image reinforces the notion that the Stasi’s work was mostly a manual, often experimental, labor. It also tells us their work in surveillance and control, which is seen as a miserable, tyrannical sort, is now standard business practice among the software-automated surveillance capitalist models of the internet used by Facebook, Google, and others. Just as Department M workers like Gerd Reinicke mined the post for intelligence and PiD, the same basic processes the Stasi developed, now used as software by Facebook, are also at work in China, Iran, and other countries to filter and control what people can say and read through elaborate censorship software systems.
