Token Dimensions

C’est mois, in my second post on Tokenization for the iovation blog:

These requirements demonstrate the two dimensions of tokenization: reversibility and determinism. Reversible tokens may be detokenized to recover their original values. Deterministic tokens are always the same given the same inputs.

The point is to evaluate the fields private data fields to be tokenized in order to determine where in along these dimensions they fall, so that one can make informed choices when evaluating tokenization products and services.
