Explanation: Hash functions are a nice example of a metric that may be used to guarantee the integrity of data. If you generate a hash value, which is a string of characters with a set length, depending on the contents of the data, you will be able to determine whether or not the data has been changed. If there is any manipulation of the data, the hash value will shift, which is an indication that there may have been a breach of integrity. Checksums and digital signatures are two examples of procedures that often make use of this.
