Question

Quizplus · Accepted Answer

Digital signatures are electronic security marks that can be added to files. They identify the publisher of a file and verify that the file has not had its integrity compromised. Digital watermarks are a similar concept, but they are more commonly used for copyright and ownership identification purposes rather than security and integrity verification. Data readers and web certificates are not directly related to electronic security marks.
