Minimization

nounverified·updated May 18, 2026

(Part of the ICO framework for auditing AI) AI systems generally require large amounts of data. However, organisations must comply with the minimisation principle under data protection law if using personal data. This means ensuring that any personal data is adequate, relevant and limited to what is necessary for the purposes for which it is processed. […] The default approach of data scientists in designing and building AI systems will not necessarily take into account any data minimisation constraints. Organisations must therefore have in place risk management practices to ensure that data minimisation requirements, and all relevant minimisation techniques, are fully considered from the design phase, or, if AI systems are bought or operated by third parties, as part of the procurement process due diligence

Data Minimization

a data controller should limit the collection of personal information to what is directly relevant and necessary to accomplish a specified purpose. They should also retain the data only for as long as is necessary to fulfil that purpose. In other words, data controllers should collect only the personal data they really need, and should keep it only for as long as they need it. The data minimisation principle is expressed in Article 5(1)(c) of the GDPR and Article 4(1)(c) of Regulation (EU) 2018/1725, which provide that personal data must be "adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed".
