AIGP Understanding How Laws, Standards and Frameworks Apply to AI Medium

  1. Collect all available profiles, then encrypt the recommendation dataset
    Encryption supports security but does not cure excessive collection unrelated to the specified recommendation purpose.
  2. Collect only data necessary for the recommendation purpose ✓
    Data minimization requires limiting collection to information necessary and relevant for the stated personalization objective.
  3. Collect biographies first, then remove addresses during deployment
    Removing unnecessary fields later does not justify collecting excessive personal data initially under the minimization principle.
  4. Collect complete histories because broader data improves personalization
    More data need not improve fitness and cannot override purpose-based necessity and minimization requirements.
The trap
Identify the minimum fields needed for the stated purpose before considering security or model performance.

How to remember it

The stated objective needs limited fields, so collection should exclude biographies, addresses, and unrelated social histories.
