Digital Trust Architecture: Data Protection and PETs

The text analyzes the transition from data centralization to the 'Visit The Data' model, where computations are moved directly to the information sources instead of gathering them in one database. The author emphasizes the difference between the right to a resource and the right to an operation, which allows for analytics to be performed without original data holders losing control over their data. A key element of this architecture is the principle of exposure minimization, implemented through technologies such as differential privacy and query-only models. In contrast to simple anonymization, the modern approach protects against the re-identification of individuals based on quasi-identifiers by introducing controlled randomness and technical access restrictions, forming the foundation of digital trust in the AI era.
