Abstract
Methods and systems of data de-tokenization are described herein to provide solutions to utilizing tokenized data files. A de-tokenization service controller may extract instances of tokenized data by determining a schema associated with a tokenized file, wherein the schema identifies which fields contain tokenized data. A decryption system may decrypt the tokens and send decrypted sensitive values to the de-tokenization service controller. The de-tokenization service controller may then generate a de-tokenized data file comprising a plurality of records corresponding to the plurality of original tokenized records, using the decrypted sensitive values in place of the instances of tokenized data. In some embodiments, the methods may further comprise generating a validated file by adding one or more fields indicating the results of validation based on a set of validation rules. The methods may further comprise re-tokenizing the de-tokenized data file, before storing the data files again in a re-tokenized data storage.
