		Our approach	Khan and Husain et al. approach
Insertion, deletion, alteration attacks		Detect and localize the; tampering at group; level and may detect the tampered tuples	Detect and characterize; malicious modification; made to the database; and characterize the; tamper attack
Database partitioning		Partition based technique	No partitioning
Multifaceted attack	Tuples insertion-deletion attacks	Resilient to such kind of attack	Resilient to such kind of attack
	Attributes substitution attacks	Resilient to such kind of attack	Not resilient to such kind of attack
