What is the role of encryption in data privacy?

• A. To make data accessible to everyone
• B. To transform data into a secure format that can only be read by authorized users
• C. To develop data redundancy procedures
• D. To ensure faster data retrieval

Answer: (B)

Encryption plays a critical role in data privacy by transforming data into a secure format that can only be read by authorized users. This process involves using algorithms to scramble the original information, making it unreadable to anyone who does not possess the correct decryption key. By ensuring that only authorized individuals can access and interpret the data, encryption safeguards sensitive information from unauthorized access and potential breaches.

The ability to protect data in transit and at rest is vital in maintaining confidentiality and integrity in various environments, such as cloud storage, online communications, and database management. This secure handling of data helps organizations comply with data protection regulations and builds trust with customers and stakeholders by prioritizing privacy.

Other options present roles that do not align with the primary purpose of encryption. For instance, making data accessible to everyone contradicts the concept of security and privacy. Developing data redundancy procedures pertains to data backup and recovery rather than securing data. Ensuring faster data retrieval is typically related to optimization techniques rather than security measures. Thus, the essential function of encryption in data privacy is its ability to secure information by restricting access to authorized parties only.
