Pseudo-anonymous data

Share data

Labelling data in such a way that is hard to traced back to a specific person – rather than using a name, a random unique identifier is used.

If data needs to be re-identified, the random identifier can be cross-referenced with data held elsewhere.

Advantages

  • Data can be processed without revealing who it relates to

  • Gives people plausible deniability by not directly relating data and a person together

Limitations

  • Sometimes possible to find patterns that identify a person
