What is the role of encryption in data integration?

Encryption plays a critical role in data integration by ensuring that sensitive data remains secure during transmission between systems. When data is transferred across networks or between different applications, the risk of interception and unauthorized access increases. Encryption addresses this concern by converting the original data (plaintext) into a coded format (ciphertext) that can only be read by an authorized party possessing the correct decryption key. This method protects the confidentiality and integrity of the data, making it unreadable to anyone who might try to intercept it, thus maintaining security and compliance with data protection regulations.

The other options do not accurately represent the primary function of encryption. For instance, while data compression can improve transmission speeds, it is not related to encryption. Creating backups pertains to data recovery and preservation rather than securing data in transit. Enhancing visibility across platforms focuses on accessibility and usability of data, rather than protecting it from unauthorized access. Therefore, the correct answer emphasizes the protective function of encryption in the context of data integration.
