Blind Key Based Attack Resistant Audio Steganography Using Cocktail Party Effect

Table 1

Advantage and disadvantage of different approaches for solving Cocktail Party Problem.

Approach for solving Cocktail Party Problem	Advantages of the method	Disadvantages of the method
Temporal binding	As shown in [44], this strategy helps	As stated in [45], this strategy results
	✓ robustness against loss of network elements	✘ inflexible refocusing of system onto events rapidly occurring in sequence
	✓ richness of representation
	✓ processing speed enhancement
Cortronic network	As mentioned in [36], in this method	As shown in [36], this technique is
	✓ there is no requirement for having knowledge of background sounds such as static, traffic, and music	✘ costly to implement as it requires a separate artificial neural network
Blind source separation	As shown in [46], in this technique	As reported in [47], in this method
	✓ there is no need for having knowledge of source signals or the process of mixing	✘ convergence speed is slow
	✓ no need for defining a cut-off frequency for separation
	✓ low computational complexity
	✓ helps signal enhancement
