Answer : 1. "encryption"
Explanation :

1. Encryption is the process of encoding data in cryptography.

2. This process transforms the plaintext or original representation of data into ciphertext or alternative representation of the data.

3. Only authorized parties should be able to decipher the ciphertext back into plaintext and access the original data.

4. Encryption in itself does not prevent interference, but it hinders interceptors from deciphering the content.
