N. Title Advantage Disadvantage
1 Digital Image forgery
detection using SIFT
feature
IEEE,2015
Reduce the require time to
detect forgery.
Less accuracy as
compare to other system.
2 Copy Move Forgery
Detection
using SIFT and
GMM
IEEE,2015
This system use the
Gaussian Mixture Model to
identify the image forgery.
The system is time
consuming.
3 Reflective SIFT for
Improving the
Detection of Copy-
Move Image Forgery
IEEE,2016
This system uses the new
technique is mirror-
reflection invariant feature
transform (MRIFT)
Less Accuracy as
compare to other system.

Title Advantage Disadvantage
4 Image Forgery
Detection based on
SIFT and k-means
IEEE,2015
This system uses the k-
means++ technique to
identify the image
forgery or duplication.
The similarity is less as
compare to others
system.
5 Copy-Move
Forgery Detection
in Digital Images
Using Affine-SIFT
IEEE,2016
This is system is uses the
affine scale invariant
feature transform
(ASIFT)
Forgery detection
performance is low than
proposed method.
