Which of the following is generally used to ensure that information transmitted over the Internet is
authentic and actually transmitted by the named sender?

A.
Biometric authentication

B.
Embedded steganographic

C.
Two-factor authentication

D.
Embedded digital signature

Explanation:

Digital signatures ensure that transmitted information can be attributed to the named sender; this
provides nonrepudiation. Steganographic techniques are used to hide messages or data within

other files. Biometric and two-factor authentication is not generally used to protect internet data
transmissions.
