Quizplus · Accepted Answer

A digital signature is designed to authenticate the identity of a user and verify the integrity of a message transmitted by that user. The other options listed do not provide both of these functions. Coding schemes may provide some level of authentication or verification, but they do not typically ensure both. Preformatted screens and check digit verification are used for data entry and verification, but they do not authenticate a user's identity or verify message integrity.
