Your writing style is your fingerprint:
The ‘creator’ of Bitcoin, Satoshi Nakamoto, is the world’s most elusive billionaire. Very few people outside of the Department of Homeland Security know Satoshi’s real name. In fact, DHS will not publicly confirm that even THEY know the billionaire’s identity. Satoshi has taken great care to keep his identity secret employing the latest encryption and obfuscation methods in his communications. Despite these efforts (according to my source at the DHS) Satoshi Nakamoto gave investigators the only tool they needed to find him — his own words.
Using stylometry one is able to compare texts to determine authorship of a particular work. Throughout the years Satoshi wrote thousands of posts and emails and most of which are publicly available. According to my source, the NSA was able to the use the ‘writer invariant’ method of stylometry to compare Satoshi’s ‘known’ writings with trillions of writing samples from people across the globe. […]
The NSA then took bulk emails and texts collected from their mass surveillance efforts. First through PRISM (a court-approved front-door access to Google and Yahoo user accounts) and then through MUSCULAR (where the NSA copies the data flows across fiber optic cables that carry information among the data centers of Google, Yahoo, Amazon, and Facebook) the NSA was able to place trillions of writings from more than a billion people in the same plane as Satoshi’s writings to find his true identity. The effort took less than a month and resulted in positive match.
Creepy if true.
