Which of the following is a function of data authentication?

Data authentication is a crucial process intended to ensure the integrity and accuracy of data during its transmission. The primary function of data authentication involves verifying that the data received by one party matches the data that was originally sent by another party. This helps to ascertain that the data has not been altered, tampered with, or corrupted during the transmission process. By confirming that received data is consistent with what was sent, organizations can trust the information being used for decision-making or other operational purposes.

The other choices do not pertain directly to the concept of data authentication. Enhancing data storage capabilities involves improving how data is saved and accessed but does not directly relate to verifying data integrity. Converting data into a different format may be necessary for various applications, but it does not serve the function of ensuring that the original data remains unchanged. Compiling data from multiple sources is about aggregation and does not involve the verification process that is central to data authentication. Therefore, the focus of option B accurately encapsulates the essence of data authentication.
