Abstract
Disclosed herein are system, method, and computer program product embodiments for vaultless tokenization. Alphanumeric values may be determined based on numeric values generated from a hash of numeric user information shuffled through a plurality of randomly generated alphanumeric tables. The numeric user information and the alphanumeric values may be used to generate a table index. Shuffled numeric user information may be generated based on the table index and a plurality of randomly generated numeric tables, and transformed to alphanumeric user information (e.g., via format-preserving encryption, additive cipher, etc.). Each character of the alphanumeric user information may be shuffled through a different alphanumeric table of the plurality of alphanumeric tables identified for the character based on the table index. Moreover, an alphanumeric token may be generated based on the shuffled characters of the alphanumeric user information.
