What aspect does data privacy emphasize?

Data privacy emphasizes the protection of sensitive information from unauthorized access and misuse. This concept is crucial in today's digital landscape, where vast amounts of personal data are collected, stored, and processed. By prioritizing data privacy, organizations aim to safeguard individuals' personal details, such as names, addresses, financial information, and health records, ensuring that this information is only accessed by individuals or systems that have the right to do so.

The focus on protecting sensitive information includes implementing measures such as encryption, access controls, and compliance with legal regulations (like GDPR or HIPAA) to ensure that data is handled responsibly. In contrast, other options diverge from this core principle. Performance of code execution, how data is stored in memory, and speed of data transmission are all factors related to computing efficiency and technical processes, but they do not directly address the critical issue of safeguarding individual privacy rights.
