Abstract
A non-tokenized string is received. For example, a non-tokenized string could be a credit card number. The non-tokenized string is partitioned into a plurality of non-tokenized substrings. For example, if the credit card number is 16 digits long, it may be partitioned into substrings that are three, six, and seven digits in length. The non-tokenized substrings are used as an index into a plurality of lookup tables. As a result of the indexing, a plurality of tokenized substrings are retrieved. The plurality of tokenized substrings are combined into a tokenized string. The tokenized string is used as a token that represents the credit card number without disclosing the actual credit card number. The reverse of the above process can also occur.
