A Fragile Zero Watermarking Scheme to Detect and Characterize Malicious Modifications in Database Relations

Table 3

Detection of malicious deletion of tuples with different attack rates (𝜂=10⁶).

Deletion attack rate	WAR	WDR	Temper detection
10%	24.32	75.68	Yes (High)
30%	17.88	82.12	Yes (High)
50%	20.95	79.05	Yes (High)
70%	13.08	86.92	Yes (High)
90%	14.14	85.86	Yes (High)
