Question 1

What problem does the paper address in audio steganography?

Accepted Answer

It addresses the security weakness of classic LSB audio steganography, where added noise in embedded LSBs can be detected due to the human auditory system’s sensitivity.

Question 2

How does the proposed XORing of LSBs method improve security?

Accepted Answer

It improves security by randomly selecting pairs of LSBs to XOR, enhancing unpredictability while preserving the core characteristics of classic LSB methods.

Question 3

How is the method validated for practical use?

Accepted Answer

The method is implemented on a Cirrus Logic DSP to demonstrate efficient operation in a real-time audio environment without interfering with human auditory sensitivity levels.
