What is the purpose of data encryption in information systems?

The purpose of data encryption in information systems is to secure sensitive information. Encryption is a process that transforms readable data into a coded format, which ensures that only authorized users can access and decode the data. This is essential in protecting personal information, financial records, and other confidential data from unauthorized access and breaches, thereby maintaining confidentiality and integrity in information systems.

For example, when data is transmitted over the internet, encryption helps safeguard it from cyber threats, ensuring that even if the data is intercepted, it remains unreadable to unauthorized parties. In today's digital landscape, where data breaches are increasingly common, encryption plays a crucial role in building trust with users and complying with various regulations related to data protection.

The other options, while important aspects of information systems, do not pertain to the specific function of data encryption. Enhancing user experience focuses on usability and design rather than security, speeding up processing is related to efficiency and performance, and organizing databases deals with data management and retrieval rather than protecting data from access.
