Which principle requires organizations to ensure that personal information is relevant and not excessive for its purposes?

The principle that requires organizations to ensure that personal information is relevant and not excessive for its purposes is known as "Limiting Collection." This principle emphasizes that when an organization collects personal information, it should only gather what is necessary to fulfill the specific purposes for which it is being collected. This means that organizations must assess their needs carefully and avoid accumulating information that does not directly relate to their intended use.

By adhering to this principle, organizations can help protect individuals' privacy by minimizing the amount of personal data they hold. It ensures that only appropriate and pertinent information is collected, reducing the risk of misuse or unnecessary exposure of sensitive data. In essence, focusing on limiting collection aligns with responsible data management practices and supports compliance with privacy laws and regulations.

The other principles, such as accuracy, identifying purposes, and consent, play significant roles in overall privacy protection but pertain to different aspects of data handling. Accuracy relates to ensuring that the information collected is correct and up to date. Identifying purposes involves informing individuals why their information is being collected, while consent focuses on obtaining permission from individuals before collecting or using their personal information.
