Abstract
A tokenization environment includes a first tokenization system in a first token domain and a second tokenization system in a second token domain. A token mapper accesses a first token from the first tokenization system and maps it to a second token from the second tokenization system. The first token can be a single-use or SLT token mapped to a clear text value within a single-use token table in the first tokenization system. The token mapper can identify the clear text value, and can query a multi-use token table in the second tokenization system with the clear text value to identify a multi-use token (the second token) mapped to the same clear text value. The token mapper can store the association between the first token and the second token in a token map.
