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.
