Texas’s approach to ‘Pseudonymous Data’ differs from what we’ve seen with other state privacy laws, and the EU’s GDPR.
Pseudonymous Data is defined as “personal data that cannot be attributed to a specific individual without the use of additional information, provided that the additional information is kept separately and is subject to appropriate technical and organizational measures to ensure that the personal data is not attributed to an identified or identifiable individual.”
Texas departs from GDPR in that TDPSA excludes Pseudonymous Data from many of the requirements applicable to Personal Data so long as it remains pseudonymized.
Whereas other state laws—including, to varying degrees, Virginia, Utah, and Indiana—make certain exceptions for de-identified and pseudonymous data, Texas goes a step further by implicitly excluding Pseudonymous Data from the definition of Personal Data.
To put a fine point on it, GDPR includes Pseudonymous Data (called “Pseudonymised Data” in EU parlance) within the definition and under the umbrella of Personal Data, applying all requirements and restrictions applicable to Personal Data to Pseudonymous Data because of the potential for it to be re-identified. For most of the requirements of TDPSA, this is not the case.
This exclusion may provide an exciting opportunity for many businesses: because if a business has processes for which direct identifiers are not necessary (e.g., name, contact information, customer number, etc.), removing these identifiers from businesses processes and the systems could result in said data being outside the purview of the TDPSA.
To reiterate: Pseudonymous Data on its own is not considered Personal Data for many of the requirements under the TDPSA.
Like recent state privacy laws in Virginia and some other states, under TDPSA, a business does not need to include pseudonymous data in its response to Individual Rights Requests.
One of the most common uses of pseudonymous data is in the clinical trial context, where each trial participant is assigned a random ID that stands in for their actual identity (their actual identity is only known to medical staff and not the sponsor/manufacturing company, labs, and other supporting entities).
