Which type of verification consists of using tools to compute the message digest of the original and copied data, then comparing the similarity of the digests?
The correct answer is B. data integrity. Data integrity verification aims to ensure that the data has remained unchanged and unaltered during the copying or transfer process. Calculating the message digest (often using hash functions like MD5, SHA-1, SHA-256) generates a unique checksum or hash value for the original…

Explanation
Data integrity verification aims to ensure that the data has remained unchanged and unaltered during the copying or transfer process. Calculating the message digest (often using hash functions like MD5, SHA-1, SHA-256) generates a unique checksum or hash value for the original and copied data. By comparing these digests, one can verify if the data's integrity has been maintained or if any alterations occurred during the copying process. This process helps in ensuring the consistency and reliability of the data being transferred or preserved.
