METHOD AND SYSTEM FOR DEANOMYMIZING CRYPTOCURRENCY USERS BY ANALYZING BANK TRANSFERS TO A CRYPTOCURRENCY EXCHANGE

Abstract:

A computerized method for deanonymizing cryptocurrency users by analyzing bank transfers to a cryptocurrency exchange may include receiving data from a currency transfer made by a user at a bank to a cryptocurrency exchange. Candidate currency exchange transactions made by the user may be identified from the currency exchange transactions completed by the cryptocurrency exchange within a predefined time interval. A set of anonymous transactions in blockchain cryptocurrency ledger in the predefined time interval may be identified where the cryptocurrency value in transactions of anonymous users in a blockchain cryptocurrency ledger matches a currency transfer amount made by the user in the candidate currency exchange transactions. Anonymous transactions in the set may be identified as being made by the user based on the probability assigned to each anonymous transaction in the set.
