https://en.bitcoin.it/wiki/Satoshi_NakamotoInvestigations into the real identity of Satoshi Nakamoto have been attempted by The New Yorker and Fast Company. The New Yorker arrived at Michael Clear, a young graduate student in cryptography at Trinity College in Dublin, who was named the top computer-science undergraduate at Trinity in 2008. The next year, he was hired by Allied Irish Banks to improve its currency-trading software, and he co-authored an academic paper on peer-to-peer technology.[1]
Fast Company's investigation brought up circumstantial evidence that indicated a link between an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August 2008, and the bitcoin.org domain name which was registered 72 hours later. The patent application contained networking and encryption technologies similar to Bitcoin's. After textual analysis, the phrase "...computationally impractical to reverse" was found in both the patent application and bitcoin's whitepaper.[2] All three inventors explicitly denied being Satoshi Nakamoto.[3][4]
