A method for distributed tokenization of sensitive strings of characters in a local server, said method comprising the steps: receiving from a central server at least one static token lookup table; receiving a sensitive string of characters; substituting a first substring of characters with a corresponding first token from said at least one token lookup table to form a first tokenized string of characters, said first substring of characters being a substring of said sensitive string of characters; and substituting a second substring of characters with a corresponding second token from said at least one token lookup table to form a second tokenized string of characters, said second substring of characters being a substring of said first tokenized string of characters.
