Distributed tokenization authentication

A system comprising:

• one or more processors;
• at least one memory device coupled with the one or more processors;
• and
• a data communications interface operably associated with the one or more processors, wherein the at least one memory device contains a plurality of program instructions that, when executed by the one or more processors, cause the one or more processors to:
• receive, by a node, an encrypted token comprising a first set of sensitive data, wherein the encrypted token was generated by a randomization service based on a mapping structure;
• determine, based on the encrypted token, a second set of sensitive data using a detokenization process;
• generate, based on the second set of sensitive data, a rebuilt token using a retokenization process;
• determine whether the encrypted token is validated by comparing the encrypted token and the rebuilt token;
• and
• in response to determine that the encrypted token is validated, provide the first set of sensitive data to an application interface of a first process executing using a first set of computing resources that are isolated from a second set of computing resources that the node allocates to the randomization service.

A computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• program code stored on the non-transitory computer-readable storage medium that, when executed by one or more processors, causes the one or more processors to:
• receive, by a node, an encrypted token comprising a first set of sensitive data, wherein the encrypted token was generated by a randomization service based on a mapping structure;
• determine, based on the encrypted token, a second set of sensitive data using a detokenization process;
• generate, based on the second set of sensitive data, a rebuilt token using a retokenization process;
• determine whether the encrypted token is validated by comparing the encrypted token and the rebuilt token;
• and
• in response to determine that the encrypted token is validated, provide the first set of sensitive data to an application interface of a first process executing using a first set of computing resources that are isolated from a second set of computing resources that the node allocates to the randomization service.
