How is data encryption defined?

Data encryption is defined as a process of converting information into code. This technique involves transforming readable data into an encoded version that can only be read or processed by those who possess the correct decryption key or password. This ensures the confidentiality and security of sensitive information during transmission or storage, as it prevents unauthorized access.

The focus on encryption as a coding process highlights its primary role in protecting data integrity and privacy, particularly in the digital world where information can be vulnerable to interception by malicious actors. By converting data into an unreadable format, encryption serves as a critical defense mechanism against cyber threats, ensuring that even if data is intercepted, it remains secure and unrecognizable without the appropriate decryption tools.
