What does the process of encryption aim to achieve?

• A. Data compression
• B. Data confidentiality
• C. Data deletion
• D. Data validation

Answer: (B)

The process of encryption aims to achieve data confidentiality by transforming readable data (plaintext) into an unreadable format (ciphertext) through the use of algorithms and encryption keys. This transformation ensures that unauthorized individuals cannot access or understand the information, even if they intercept it. By securing data in this way, organizations can protect sensitive information from being disclosed or misused, thus maintaining privacy compliance and safeguarding the trust of customers and stakeholders.

Data compression focuses on reducing the size of data for storage efficiency, while data deletion involves permanently removing data from a system. Data validation ensures the accuracy and quality of data but does not involve making it unreadable. In contrast, encryption directly safeguards the integrity of the data itself by preventing unauthorized access, making data confidentiality its primary goal.
