Correct Answer - Option 1 : Encryption

The correct answer is Encryption.

  • Encryption is the process of encoding data in cryptography.
  • This procedure converts plaintext, or the original representation of the data, into ciphertext, or an alternative representation of the data.
  • Only authorized parties should be able to decipher a ciphertext back to plaintext and access the original data.
  • Encryption does not prevent interference in and of itself, but it does hinder a would-be interceptor from understanding the material.
  • The act of verifying an assertion, such as a computer system user's identity, is known as authentication.
