In 2020, the Eurоpeаn Uniоn’s COVID-19 cоntаct-trаcing apps faced public concern over privacy.

In contrast, others used a decentralized model (where data remained locally on users’ devices and only anonymized tokens were exchanged). Both systems aimed to alert users to exposure, but privacy experts argued that the centralized model posed structural risks of surveillance and misuse. From a Privacy by Design standpoint, which principle best explains why the decentralized architecture was preferred?
