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

Table 2

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

Insertion attack rate	WAR	WDR	Temper detection
10%	18.14	81.86	Yes (High)
30%	18.56	81.44	Yes (High)
50%	20.41	79.59	Yes (High)
70%	16.67	83.33	Yes (High)
90%	16.32	83.68	Yes (High)
