What defines data that cannot be intercepted or modified while being transmitted?

The term defining data that cannot be intercepted or modified while being transmitted is best understood as "encrypted data." Encryption involves converting information into a coded format that can only be accessed or understood by someone who has the correct decryption key. This process ensures that even if data is intercepted during transmission, it will appear as gibberish or unreadable content to an unauthorized user, protecting the integrity and confidentiality of the original information.

Secure data generally refers to data protected by various means, which could include encryption, but it does not specifically address the transmission aspect. Compressed data involves reducing the size of the data for efficiency in storage or transmission, but that process does not inherently secure the data. Accessible data means that the data can be easily retrieved or utilized, which does not correlate with interception or modification during transmission. Thus, "encrypted data" more accurately describes the situation where interception or modification cannot occur effectively.
