Vaultless tokenization
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.

shuffling each character of the alphanumeric user information through a different alphanumeric table of the plurality of randomly generated alphanumeric tables, wherein each different alphanumeric table is identified for each character based on the table index; and
generating an alphanumeric token based on the shuffled characters of the alphanumeric user information;
determining a numeric value indicative of an amount of numeric characters of the numeric user information; and

determining a numeric value indicative of an amount of numeric characters of the numeric user information; and
modifying the generated alphanumeric token to include an alphabetic value, wherein the alphabetic value is determined based on an alphabetic representation of the numeric value that is shuffled through a plurality of randomly generated alphabetic tables.
8. The non-transitory computer-readable medium of claim 7 , the operations further comprising padding the alphanumeric token with a randomly generated numeric character based on an indication that a numeric character of the numeric user information is removed according to the numeric user information being shuffled through the plurality of randomly generated numeric tables.
9. The non-transitory computer-readable medium of claim 7 , the operations further comprising padding the alphanumeric token with the alphanumeric values.
10. The non-transitory computer-readable medium of claim 7 , the operations further comprising:
