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.

C’est mois, in the first of a series for the iovation blog:

Given our commitment to responsible data stewardship, as well as the invalidation of Safe Harbor and the advent of the GDPR, we saw an opportunity to reduce these modest but very real risks without impacting the efficacy of our services. A number of methodologies for data protection exist, including encryption, strict access control, and tokenization. We undertook the daunting task to determine which approaches best address data privacy compliance requirements and work best to protect customers and users — without unacceptable impact on service performance, cost to maintain infrastructure, or loss of product usability.

The post covers encryption, access control, and tokenization.
