Q91.
What is the Secure Audio Path Model?

a.

A method to encrypt audio files

b.

A way to control the flow of unencrypted copyrighted audio within Windows

c.

A system to protect the decryption key for audio files

d.

None of the above

Discuss
Answer: (b).A way to control the flow of unencrypted copyrighted audio within Windows Explanation:The Secure Audio Path Model attempts to control the flow of copyrighted, unencrypted audio within Windows.
Q92.
Why is the Secure Audio Path Model necessary?

a.

To encrypt audio files

b.

To control the flow of unencrypted copyrighted audio within Windows

c.

To protect the decryption key for audio files

d.

None of the above

Discuss
Answer: (b).To control the flow of unencrypted copyrighted audio within Windows Explanation:The problem is that anyone can write a simulated audio device driver that would just steal the decrypted content while the media playback software is sending it to the sound card. The Secure Audio Path ensures that the copyrighted audio remains in the kernel and is only transmitted to audio drivers that were signed by a trusted authority.
Q93.
What is the purpose of the Secure Audio Path Model?

a.

To prevent unauthorized access to copyrighted audio

b.

To encrypt audio files

c.

To limit the number of authorized users for audio files

d.

None of the above

Discuss
Answer: (a).To prevent unauthorized access to copyrighted audio Explanation:The Secure Audio Path Model attempts to control the flow of copyrighted, unencrypted audio within Windows to prevent unauthorized access to the copyrighted audio.
Q94.
What is watermarking?

a.

A process of adding an additional channel of visible data

b.

A process of adding an additional channel of audible data

c.

A process of adding an additional channel of imperceptible data

d.

A process of adding an additional channel of encrypted data

Discuss
Answer: (c).A process of adding an additional channel of imperceptible data Explanation:Watermarking is the process of adding an additional channel of imperceptible data alongside a visible stream of data.
Q95.
What are the basic properties of a good watermarking scheme?

a.

Difficult to remove, contains as much information as possible, imperceptible, easy to detect, unencrypted, non-robust

b.

Easy to remove, contains little information, perceptible, difficult to detect, encrypted, robust

c.

Difficult to remove, contains as much information as possible, imperceptible, difficult to detect, encrypted, robust

d.

Easy to remove, contains as little information as possible, perceptible, easy to detect, unencrypted, non-robust

Discuss
Answer: (c).Difficult to remove, contains as much information as possible, imperceptible, difficult to detect, encrypted, robust Explanation:The basic properties of a good watermarking scheme are that it is difficult to remove, contains as much information as possible, imperceptible, difficult to detect, encrypted, and robust.
Q96.
What is the purpose of software watermarking?

a.

To modify a program's functionality

b.

To hide a program's binary code

c.

To add a hidden data storage channel within a program's binary code

d.

To make a program unreadable

Discuss
Answer: (c).To add a hidden data storage channel within a program's binary code Explanation:Software watermarking is the process of modifying a program's binary code in a way that doesn't affect its functionality but allows for a hidden data storage channel within the binary code.
Q97.
What are the applications of watermarking?

a.

Enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and modifying a program's functionality

b.

Enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and hiding a program's binary code

c.

Enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and adding a hidden data storage channel within a program's binary code

d.

Enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and making a program unreadable

Discuss
Answer: (c).Enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and adding a hidden data storage channel within a program's binary code Explanation:The applications of watermarking include enabling authors to embed identifying information in their intellectual property, identifying the specific owner of an individual copy, identifying the original, unmodified data, and adding a hidden data storage channel within a program's binary code.
