Which principle emphasizes the need for information regarding personal data processing to be easy to access and understand?

The principle that emphasizes the need for information regarding personal data processing to be easy to access and understand is transparency. This principle is vital in the context of data protection because it fosters trust between individuals and organizations that handle personal data. Transparency ensures that data subjects are well-informed about how their data is being collected, used, stored, and shared, allowing them to make informed decisions regarding their personal information.

By prioritizing transparency, organizations are required to provide clear and comprehensible information about their data practices, which includes the purpose of data collection, the entities involved in processing, and the rights of the individuals. This openness helps mitigate concerns regarding privacy violations and promotes accountability within organizations.

In contrast, the other principles focus on different aspects of data handling. For instance, the legitimate purpose principle relates to collecting data only for specific, legitimate reasons. Proportionality refers to ensuring that the amount of personal data collected is appropriate and relevant for the intended purpose. Sensitivity addresses the protection of more vulnerable data types, such as health-related information. Each of these principles plays a critical role in data privacy, but it is transparency that specifically highlights the importance of accessible and understandable information for data subjects.
