How the Data Privacy Periodic Table works

This project is designed to make the cloudy and complicated world of Data Privacy easier to understand. The first step of that is to decipher the language and technical terminology.

Therefore, just as with the real periodic table, we have ordered the “elements of data privacy” into suitable categories according to their traits. We also regularly update it as the data privacy landscape changes and new elements come to light.

Our table’s categories mimic the characteristics of the original scientific version’s categories. For example, the far right of the original periodic table is reserved for the “noble gases” – stable, inert and neutral. This seemed an ideal match for the independent legislative or regulatory bodies.

Similarly, the column on the far left usually dedicated to the alkali metals, with their characteristic volatility, was a fitting location for the universal rights of the data subject. If meddled with, both are likely to cause an explosion!

The grid below sets out the detail of how and why we have set out the table in the way we have.

How the Data Privacy Periodic Table has evolved

The data privacy world is constantly moving. And every time we update the table to reflect recent changes, it triggers debate!

There are only 118 boxes available to us, and the data privacy world is far too complex to be encapsulated in such a small number of elements, so we always have to make some hard – and sometimes controversial – decisions. But with every update, we have explained our thinking in the blogs below.

This is intended to be a collaborative, cross-industry initiative, so we would welcome any comments or suggestions for new additions or changes – contact our Privacy lead here with any recommendations.

  • Original Launch: Including explanatory notes on the position of Ethics, the myth of Compliance, how we represented Data Subjects and others
  • Update 1: Including changes to the Independent Bodies section, addition of KYC and a debate over the Right to be Informed
  • Update 2: Especially for Data Protection Day 2019. Changes to the Future Developments and Core Legislation sections to reflect new regulations, such as moving the position of the California Consumer Privacy Act and adding Brazil and Bahrain’s new legislation.
  • Update 3: Changes made to ensure the included elements are more representative of Privacy generally, and not too GDPR-centric, plus some amends to Future Developments to include US States’ legislation.
