In some embodiments, the methods and systems generate a cookie based on a confirmed user purchase, and record the user identity contained in the cookie at a block chain to identify the user as a verified purchaser. The methods and systems may later retrieve the cookie and search the block chain using the user identity contained in the cookie. By locating the user identity in the block chain, the methods and systems know that the user is a verified purchaser, indicating the user to be a person, as robots cannot make purchases.
