Table 6

Performance comparisons with MSB-based schemes.

Watermarking scheme	PSNR of watermarked image (dB)	PSNR of recovered content (dB)	Condition of successful restoration
Scheme 1 in [19]	38	40.7	Tampering rate ≤24%
Scheme 2 in [19]	38	[22, 40]	Tampering rate ≤66%
Scheme in [33]	38	[31, 42]	Tampering rate ≤50%
Proposed scheme	38	[22, 41]	Tampering rate ≤80%
