Verifiable tokenization

A system for tokenizing data comprising:

• a non-transitory computer-readable storage medium comprising executable computer instructions configured to:
• receive 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;
• query 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, generate 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
• store 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;
• and
• a processor configured to execute computer instructions.

A non-transitory computer-readable storage medium storing executable computer instructions for tokenizing data, the instructions, when executed, configured to perform steps comprising:

• receiving 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.
