An IS auditor reviewing digital rights management (DRM) applications should expect to find an extensive use
for which of the following technologies?

A.
Digitalized signatures

B.
Hashing

C.
Parsing

D.
Steganography

Explanation:
Steganography is a technique for concealing the existence of messages or information. An increasingly
important steganographical technique is digital watermarking, which hides data within data, e.g., by encoding
rights information in a picture or music file without altering the picture or music’s perceivable aesthetic qualities.
Digitalized signatures are not related to digital rights management. Hashing creates a message hash or digest,
which is used to ensure the integrity of the message; it is usually considered a part of cryptography. Parsing is
the process of splitting up a continuous stream of characters for analytical purposes, and is widely applied in
the design of programming languages or in data entry editing.
