Claim One:
1. A computer-implemented method for retokenizing data, comprising: accessing, by an input module of a tokenization system, tokenized data comprising data tokenized using a single-use token value such that a portion of the tokenized data comprises the single-use token value; accessing, by a token mapping module of the tokenization system, a tokenization domain table mapping each of a plurality of single-use token values to an associated multi-use token value, wherein for each single-use token value mapped to a multi-use token value, a single-use token table maps the single-use token value to a clear text value, and a multi-use token table maps the multi-use token value to the same clear text value; querying, by a tokenization engine of the tokenization system, the accessed tokenization domain table using the single-use token value to identify a multi-use token value mapped to the single-use token value; retokenizing, by the tokenization engine of the tokenization system, the tokenized data by replacing the portion of the tokenized data comprising the single-use token value with the multi-use token value; and outputting, by an output module of the tokenization system, the retokenized data to a target entity.
