Abstract
Use rules are included within tokenized data either before or after tokenization. The use rules can be appended to the data before or after tokenization, can be used to modify the data before or after tokenization, and can be used to select or generate token tables for use in tokenizing the data. The use rules limit how, where, and when the tokenized data can be used, who can use the tokenized data, and the like. In addition, data can be tokenized such that the tokenized data can be identified as tokenized based on the tokenized data failing a validation test. The data is tokenized using one or more token tables, and the validation test is applied to the tokenized data. If the tokenized data passes the validation test, the data is modified with formatting rules or re-tokenized with additional token tables until the tokenized data fails the validation test.
