Allegedly using word surveillance and stylometry the effort took less than a month. Apparently using encryption and complex obfuscation methods is not a defence when the “seeker” has access to trillions of writing samples from a billion or so people across the globe.
“By taking Satoshi’s texts and finding the 50 most common words, the NSA was able to break down his text into 5,000 word chunks and analyse each to find the frequency of those 50 words. This would result in a unique 50-number identifier for each chunk. The NSA then placed each of these numbers into a 50-dimensional space and flatten them into a plane using principal components analysis. The result is a ‘fingerprint’ for anything written by Satoshi that could easily be compared to any other writing.”
It is worth noting that the original post is littered with comments that request more details on the source of the information that informed the post or some other such proof of the veracity of the claims being made but the author declared in response:
“Many readers have asked that I provide third party citations to ‘prove’ the NSA identified Satoshi using stylometry. Unfortunately, I cannot as I haven’t read this anywhere else — hence the reason I wrote this post. I’m not trying to convince the reader of anything, instead my goal is to share the information I received and make the reader aware of the possibility that the NSA can easily determine the authorship of any email through the use of their various sources, methods, and resources.”
“Many readers have asked who Satoshi is and I’ve made it clear that information wasn’t shared with me. Based on my conversation I got the impression (never confirmed) that he might have been more than one person. This made me think that perhaps the Obama administration was right that Bitcoin was created by a state actor. One person commented on this post that Satoshi was actually four people. Again, I have no idea.”
If it is true then “The moral of the story? You can’t hide on the internet anymore. Your sentence structure and word use is MORE unique than your own fingerprint. If an organization, like the NSA, wants to find you [sic] they will.”
