Part II. Are you a public or private organisation assessing your technology for the GDPR?

In this series, Trilateral Research analyses key risk assessment areas for the GDPR implementation. This second week, we are looking into the assessment of data storage, retention, and deletion.  This series is an opportunity to share insights into technical areas we often analyse for our clients in the private and public sector, such as:

Assessment of data storage, retention, and deletion
Data is generally stored using a combination of different database technologies such as

  • in-memory
  • disk-based
  • cache
  • buffer

Typically, the design of these databases are based on the business purpose such as:

  • processing requirements (real-time/batch)
  • access speed (read/write)
  • storage requirements (permanent/temporarily)

Another element is data management in terms of backup, retention, and deletion which could be made either time-dependent (minutes, hourly, daily, monthly, yearly) or rule-based (consent, opt-in/opt-out, receiving of updated data).

Information on such storage, retention and deletion requirements are required for completion of Data Protection Impact Assessments when producing the systematic description of the system under examination. It is also valuable information when assessing complex questions around the linkability of data which feeds into the ability to de-anonymise individuals by combining datum stored in disparate databases.
