[10] Suppose we want to provide data privacy using block cipher modes of operation when data is sent over the public Internet, and our notion for privacy in this context, more specifically, is that any information about encrypted data/cipherterts cannot be inferred in addition to confidentiality, given ciphertexts. We have seen ECB and CBC encryption modes in the class. Given these two modes, explain which mode provides privacy and which mode not, following the above notion. You can use examples to justify your answer.
