Which aspect of data security deals with ensuring that personal information is used ethically?

The correct choice centers on information privacy, which is focused specifically on the ethical use and protection of personal information. This concept emphasizes the right of individuals to control their own data, ensuring that it is collected, stored, and shared in a manner that aligns with ethical standards and respects individual rights.

Information privacy encompasses various practices, such as obtaining consent before handling personal data, implementing measures to protect data from unauthorized access, and ensuring that individuals are informed about how their data will be used. This is critical in today's digital landscape, where personal information can be easily collected and misused.

In contrast, the other concepts relate to different aspects of data management. Data integrity refers to the accuracy and consistency of data over its lifecycle, focusing on ensuring that the data is reliable and free of corruption. Data availability relates to ensuring that information is accessible to authorized users when needed, emphasizing the uptime and accessibility of systems. Data security is a broader term encompassing measures taken to protect data from breaches and unauthorized access but does not specifically address the ethical considerations surrounding personal information use.

Thus, the focus on ethical usage within the framework of personal information clearly aligns with the principles of information privacy.
