1. A computer-implemented method for tokenizing data comprising:

  • generating, by a central token management system, a unique set of values for each of a plurality of clients communicatively coupled to the central token management system, wherein each unique set of values is generated by the central token management system for the plurality of clients to avoid collisions between token values generated by the plurality of clients based on the unique sets of values;

    providing, by the central token management system, each generated unique set of values to a corresponding client of the plurality of clients, each client configured to generate one or more token values based on a value within the unique set of values corresponding to the client and to store the generated token values in a token table mapping the generated token values to corresponding input values;

    receiving, by the central token management system, a request from a requesting client of the plurality of clients for an additional unique set of values;

    generating, by the central token management system, the additional unique set of values to avoid collisions with the previously generated unique sets of values; and

    providing, by the central token management, the additional unique set of values to the requesting client.
