Claim Text:
1. A computer-implemented method for tokenizing data comprising: receiving, by a computing device, data to be tokenized, the received data configured to pass a validation test that determines data validity based on a result of an operation performed on all or part of the received data; querying a token table with a portion of the received data, the token table mapping each of a plurality of input values to a different token value; in response to the token table not including a token value mapped to a value of the portion of the received data, generating a token value such that replacing the portion of the received data with the generated token value produces tokenized data that does not pass the validation test; and storing the generated token value within the token table such that the generated token value is mapped to the value of the portion of the received data.
